For widgets that can be "activated" (buttons, menu items, etc.) this function activates them. Activation is what happens when you press Enter on a widget during key navigation. If widget isn't activatable, the function returns FALSE.

Returns:

Boolean

Activates the default widget for the window, unless the current focused widget has been configured to receive the default action (see gtk_widget_set_receives_default()), in which case the focused widget is activated.

Returns:

Boolean

Activates the current focused widget within the window.

Returns:

Boolean

Activates mnemonics and accelerators for this GtkWindow. This is normally called by the default ::key_press_event handler for toplevel windows, however in some cases it may be useful to call this directly when overriding the standard key handling for a toplevel window.

Parameters:

Gdk.EventKey event Required (not null)

Returns:

Boolean

Adds widget to container. Typically used for simple containers such as GtkWindow, GtkFrame, or GtkButton; for more complicated layout containers such as GtkBox or GtkTable, this function will pick default packing parameters that may not be correct. So consider functions such as gtk_box_pack_start() and gtk_table_attach() as an alternative to gtk_container_add() in those cases. A widget may be added to only one container at a time; you can't place the same widget inside two different containers.

Parameters:

Gtk.Widget widget Required (not null)

Returns:

none

Associate accel_group with window, such that calling gtk_accel_groups_activate() on window will activate accelerators in accel_group.

Parameters:

Gtk.AccelGroup accel_group Required (not null)

Returns:

none

Parameters:

String accel_signal Required (not null)

Gtk.AccelGroup accel_group Required (not null)

Number accel_key Required (not null)

Gdk.ModifierType accel_mods Required (not null)

Gtk.AccelFlags accel_flags Required (not null)

Returns:

none

Adds a child to buildable. type is an optional string describing how the child should be added.

Parameters:

Gtk.Builder builder Required (not null)

GObject.Object child Required (not null)

String type

kind of child or NULL

Returns:

none

Parameters:

Number xid Required (not null)

Returns:

none

Adds the events in the bitfield events to the event mask for

Parameters:

Number events Required (not null)

Returns:

none

Adds a mnemonic to this window.

Parameters:

Number keyval Required (not null)

Gtk.Widget target Required (not null)

Returns:

none

Adds a widget to the list of mnemonic labels for this widget. (See gtk_widget_list_mnemonic_labels()). Note the list of mnemonic labels for the widget is cleared when the widget is destroyed, so the caller must make sure to update its internal state at this point as well, by using a connection to the GtkWidget::destroy signal or a weak notifier.

Parameters:

Gtk.Widget label Required (not null)

Returns:

none

Starts moving a window. This function is used if an application has window movement grips. When GDK can support it, the window movement will be done using the standard mechanism for the window manager or windowing system. Otherwise, GDK will try to emulate window movement, potentially not all that well, depending on the windowing system.

Parameters:

Number button Required (not null)

Number root_x Required (not null)

Number root_y Required (not null)

Number timestamp Required (not null)

Returns:

none

Starts resizing a window. This function is used if an application has window resizing controls. When GDK can support it, the resize will be done using the standard mechanism for the window manager or windowing system. Otherwise, GDK will try to emulate window resizing, potentially not all that well, depending on the windowing system.

Parameters:

Gdk.WindowEdge edge Required (not null)

Number button Required (not null)

Number root_x Required (not null)

Number root_y Required (not null)

Number timestamp Required (not null)

Returns:

none

Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This is done by emitting the GtkWidget::can-activate-accel signal on widget; if the signal isn't overridden by a handler or in a derived widget, then the default check is that the widget must be sensitive, and the widget and all its ancestors mapped.

Parameters:

Number signal_id Required (not null)

Returns:

Boolean

Returns:

none

This function is used by custom widget implementations; if you're writing an app, you'd use gtk_widget_grab_focus() to move the focus to a particular widget, and gtk_container_set_focus_chain() to change the focus tab order. So you may want to investigate those functions instead. gtk_widget_child_focus() is called by containers as the user moves around the window using keyboard shortcuts. direction indicates what kind of motion is taking place (up, down, left, right, tab forward, tab backward). gtk_widget_child_focus() emits the GtkWidget::focus signal; widgets override the default handler for this signal in order to implement appropriate focus behavior. The default ::focus handler for a widget should return TRUE if moving in direction left the focus on a focusable location inside that widget, and FALSE if moving in direction moved the focus outside the widget. If returning TRUE, widgets normally call gtk_widget_grab_focus() to place the focus accordingly; if returning FALSE, they don't modify the current focus location. This function replaces gtk_container_focus() from GTK+ 1.2. It was necessary to check that the child was visible, sensitive, and focusable before calling gtk_container_focus(). gtk_widget_child_focus() returns FALSE if the widget is not currently in a focusable state, so there's no need for those checks.

Parameters:

Gtk.DirectionType direction Required (not null)

Returns:

Boolean

Gets the value of a child property for child and container.

Parameters:

Gtk.Widget child Required (not null)

String property_name Required (not null)

GObject.Value value Required (not null)

Returns:

none

Emits a GtkWidget::child-notify signal for the child property child_property on widget. This is the analogue of g_object_notify() for child properties.

Parameters:

String child_property Required (not null)

class of widget's parent

Returns:

none

Sets a child property for child and container.

Parameters:

Gtk.Widget child Required (not null)

String property_name Required (not null)

GObject.Value value Required (not null)

Returns:

none

Returns the type of the children supported by the container. Note that this may return G_TYPE_NONE to indicate that no more children can be added, e.g. for a GtkPaned which already has two children.

Returns:

Number

Same as gtk_widget_path(), but always uses the name of a widget's type, never uses a custom name set with gtk_widget_set_name().

Returns:

path_length: Number

path: String

path_reversed: String

Constructs a child of buildable with the name name. GtkBuilder calls this function if a "constructor" has been specified in the UI definition.

Parameters:

Gtk.Builder builder Required (not null)

String name Required (not null)

Returns:

GObject.Object

Creates a new PangoContext with the appropriate font map, font description, and base direction for drawing text for this widget. See also gtk_widget_get_pango_context().

Returns:

Pango.Context

Creates a new PangoLayout with the appropriate font map, font description, and base direction for drawing text for this widget. If you keep a PangoLayout created in this way around, in order to notify the layout of changes to the base direction or font of this widget, you must call pango_layout_context_changed() in response to the GtkWidget::style-set and GtkWidget::direction-changed signals for the widget.

Parameters:

String text Required (not null)

Returns:

Pango.Layout

This is similar to gtk_buildable_parser_finished() but is called once for each custom tag handled by the buildable.

Parameters:

Gtk.Builder builder Required (not null)

GObject.Object child

child object or NULL for non-child tags

String tagname Required (not null)

void* data Required (not null)

Returns:

none

This is called at the end of each custom element handled by the buildable.

Parameters:

Gtk.Builder builder Required (not null)

GObject.Object child

child object or NULL for non-child tags

String tagname Required (not null)

void* data Required (not null)

Returns:

none

This is called for each unknown element under <child>. if it doesn't.

Parameters:

Gtk.Builder builder Required (not null)

GObject.Object child

child object or NULL for non-child tags

String tagname Required (not null)

GLib.MarkupParser parser Required (not null)

void* data Required (not null)

to parser functions

Returns:

Boolean

Asks to deiconify (i.e. unminimize) the specified window. Note that you shouldn't assume the window is definitely deiconified afterward, because other entities (e.g. the user or window manager) could iconify it again before your code which assumes deiconification gets to run. You can track iconification via the "window-state-event" signal on GtkWidget.

Returns:

none

Destroys a widget. Equivalent to gtk_object_destroy(), except that you don't have to cast the widget to GtkObject. When a widget is destroyed, it will break any references it holds to other objects. If the widget is inside a container, the widget will be removed from the container. If the widget is a toplevel (derived from GtkWindow), it will be removed from the list of toplevels, and the reference GTK+ holds to it will be removed. Removing a widget from its container or the list of toplevels results in the widget being finalized, unless you've added additional references to the widget with g_object_ref(). In most cases, only toplevel widgets (windows) require explicit destruction, because when you destroy a toplevel its children will be destroyed as well.

Returns:

none

This function sets *widget_pointer to NULL if widget_pointer != NULL. It's intended to be used as a callback connected to the "destroy" signal of a widget. You connect gtk_widget_destroyed() as a signal handler, and pass the address of your widget variable as user data. Then when the widget is destroyed, the variable will be set to NULL. Useful for example to avoid multiple copies of the same dialog.

Parameters:

Gtk.Widget widget_pointer Required (not null)

address of a variable that contains widget

Returns:

none

In GTK+ 1.2, this function would immediately render the region area of a widget, by invoking the virtual draw method of a widget. In GTK+ 2.0, the draw method is gone, and instead gtk_widget_draw() simply invalidates the specified region of the widget, then updates the invalid region of the widget immediately. Usually you don't want to update the region immediately for performance reasons, so in general gtk_widget_queue_draw_area() is a better choice if you want to draw a region of a widget.

Parameters:

Gdk.Rectangle area Required (not null)

Returns:

none

Ensures that widget has a style (widget->style). Not a very useful function; most of the time, if you want the style, the widget is realized, and realized widgets are guaranteed to have a style already.

Returns:

none

Notifies the user about an input-related error on this widget. If the GtkSettings:gtk-error-bell setting is TRUE, it calls gdk_window_beep(), otherwise it does nothing. Note that the effect of gdk_window_beep() can be configured in many ways, depending on the windowing backend and the desktop environment or window manager that is used.

Returns:

none

Rarely-used function. This function is used to emit the event signals on a widget (those signals should never be emitted without using this function to do so). If you want to synthesize an event though, don't use this function; instead, use gtk_main_do_event() so the event will behave as if it were in the event queue. Don't synthesize expose events; instead, use gdk_window_invalidate_rect() to invalidate a region of the window. the event was handled)

Parameters:

Gdk.Event event Required (not null)

Returns:

Boolean

Invokes callback on each child of container, including children that are considered "internal" (implementation details of the container). "Internal" children generally weren't added by the user of the container, but were added by the container implementation itself. Most applications should use gtk_container_foreach(), rather than gtk_container_forall().

Parameters:

Function (Widget widget, void* data) : none Required (not null)

void* callback_data Required (not null)

Returns:

none

Invokes callback on each non-internal child of container. See gtk_container_forall() for details on what constitutes an "internal" child. Most applications should use gtk_container_foreach(), rather than gtk_container_forall().

Parameters:

Function (Widget widget, void* data) : none Required (not null)

void* callback_data Required (not null)

Returns:

none

Parameters:

Function (Widget widget, void* data) : none Required (not null)

Function (Object object, void* data, Number n_args, Arg args) : none Required (not null)

void* callback_data Required (not null)

Function (void* data) : none Required (not null)

Returns:

none

Stops emission of GtkWidget::child-notify signals on widget. The signals are queued until gtk_widget_thaw_child_notify() is called on widget. This is the analogue of g_object_freeze_notify() for child properties.

Returns:

none

Asks to place window in the fullscreen state. Note that you shouldn't assume the window is definitely full screen afterward, because other entities (e.g. the user or window manager) could unfullscreen it again, and not all window managers honor requests to fullscreen windows. But normally the window will end up fullscreen. Just don't write code that crashes if not. You can track the fullscreen state via the "window-state-event" signal on GtkWidget.

Returns:

none

Gets the value set by gtk_window_set_accept_focus().

Returns:

Boolean

Returns the accessible object that describes the widget to an assistive technology. If no accessibility library is loaded (i.e. no ATK implementation library is loaded via GTK_MODULES or via another application library, such as libgnome), then this AtkObject instance may be a no-op. Likewise, if no class-specific AtkObject implementation is available for the widget instance in question, it will inherit an AtkObject implementation from the first ancestor class for which such an implementation is defined. The documentation of the ATK library contains more information about accessible objects and their uses.

Returns:

Atk.Object the AtkObject associated with widget

Returns the GtkAction that widget is a proxy for. See also gtk_action_get_proxies(). NULL, if it is not attached to an action.

Returns:

Gtk.Action

Returns container's active EphyEmbed.

Returns:

Epiphany.EphyEmbed container's active child

Retrieves the widget's allocation.

Returns:

Gdk.Rectangle

Gets the first ancestor of widget with type widget_type. For example, gtk_widget_get_ancestor (widget, GTK_TYPE_BOX) gets the first GtkBox that's an ancestor of widget. No reference will be added to the returned widget; it should not be unreferenced. See note about checking for a toplevel GtkWindow in the docs for gtk_widget_get_toplevel(). Note that unlike gtk_widget_is_ancestor(), gtk_widget_get_ancestor() considers widget to be an ancestor of itself.

Parameters:

Number widget_type Required (not null)

Returns:

Gtk.Widget the ancestor widget, or NULL if not found

Determines whether the application intends to draw on the widget in an GtkWidget::expose-event handler. See gtk_widget_set_app_paintable()

Returns:

Boolean

Retrieves the border width of the container. See gtk_container_set_border_width().

Returns:

Number

Determines whether widget can be a default widget. See gtk_widget_set_can_default().

Returns:

Boolean

Determines whether widget can own the input focus. See gtk_widget_set_can_focus().

Returns:

Boolean

Gets the child of the GtkBin, or NULL if the bin contains no child widget. The returned widget does not have a reference added, so you do not need to unref it.

Returns:

Gtk.Widget pointer to child of the GtkBin

This function is only for use in widget implementations. Obtains geometry on the widget (e.g. with gtk_widget_set_size_request()), in which case it returns that geometry instead of the widget's requisition. This function differs from gtk_widget_size_request() in that it retrieves the last size request value from widget->requisition, while gtk_widget_size_request() actually calls the "size_request" method on widget to compute the size request and fill in widget->requisition, and only then returns widget->requisition. Because this function does not call the "size_request" method, it can only be used when you know that widget->requisition is up-to-date, that is, gtk_widget_size_request() has been called since the last time a resize was queued. In general, only container implementations have this information; applications should use gtk_widget_size_request().

Parameters:

Gtk.Requisition requisition Required (not null)

Returns:

none

Gets the value set with gtk_widget_set_child_visible(). If you feel a need to use this function, your code probably needs reorganization. This function is only useful for container implementations and never should be called by an application.

Returns:

Boolean

Returns the container's non-internal children. See gtk_container_forall() for details on what constitutes an "internal" child.

Returns:

Array a newly-allocated list of the container's non-internal children.

Returns the EphyWebViewChrome flags indicating the visibility of several parts of the UI.

Returns:

Epiphany.EphyWebViewChrome

Returns the clipboard object for the given selection to be used with widget. widget must have a GdkDisplay associated with it, so must be attached to a toplevel window. clipboard already exists, a new one will be created. Once a clipboard object has been created, it is persistent for all time.

Parameters:

Gdk.Atom selection Required (not null)

to use. GDK_SELECTION_CLIPBOARD gives the default clipboard. Another common value is GDK_SELECTION_PRIMARY, which gives the primary X selection.

Returns:

Gtk.Clipboard the appropriate clipboard object. If no

Gets the colormap that will be used to render widget. No reference will be added to the returned colormap; it should not be unreferenced.

Returns:

Gdk.Colormap the colormap used by widget

Parameters:

Number data_id Required (not null)

Returns:

void*

Returns whether the window has been set to have decorations such as a title bar via gtk_window_set_decorated().

Returns:

Boolean

Gets the default size of the window. A value of -1 for the width or height indicates that a default size has not been explicitly set for that dimension, so the "natural" size of the window will be used.

Returns:

width: Number

height: Number

Returns the default widget for window. See gtk_window_set_default() for more details.

Returns:

Gtk.Widget

Returns whether the window has been set to have a close button via gtk_window_set_deletable().

Returns:

Boolean

Returns whether the window will be destroyed with its transient parent. See gtk_window_set_destroy_with_parent ().

Returns:

Boolean

Gets the reading direction for a particular widget. See gtk_widget_set_direction().

Returns:

Gtk.TextDirection

Get the GdkDisplay for the toplevel window associated with this widget. This function can only be called after the widget has been added to a widget hierarchy with a GtkWindow at the top. In general, you should only create display specific resources when a widget has been realized, and you should free those resources when the widget is unrealized.

Returns:

Gdk.Display the GdkDisplay for the toplevel for this widget.

Determines whether the widget is double buffered. See gtk_widget_set_double_buffered()

Returns:

Boolean

Returns the event mask for the widget (a bitfield containing flags from the GdkEventMask enumeration). These are the events that the widget will receive.

Returns:

Number

Retrieves the extension events the widget will receive; see gdk_input_set_extension_events().

Returns:

Gdk.ExtensionMode

Retrieves the current focused widget within the window. Note that this is the widget that would have the focus if the toplevel window focused; if the toplevel window is not focused then gtk_widget_has_focus (widget) will not be TRUE for the widget.

Returns:

Gtk.Widget the currently focused widget, or NULL if there is none.

Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores NULL in has been set explicitly.

Boolean

Retrieves the vertical focus adjustment for the container. See gtk_container_set_focus_vadjustment(). none has been set.

Returns:

Gtk.Adjustment the vertical focus adjustment, or NULL if

framebuffer port; see gtk_window_set_has_frame(). It will not return the size of the window border drawn by the window manager, which is the normal case when using a windowing system. See gdk_window_get_frame_extents() to get the standard window border extents.) Retrieves the dimensions of the frame window for this toplevel. See gtk_window_set_has_frame(), gtk_window_set_frame_dimensions().

Returns:

left: Number

Returns:

Boolean

Determines whether widget has a GdkWindow of its own. See gtk_widget_set_has_window().

Returns:

GdkPixbuf.Pixbuf icon for window

Retrieves the list of icons set by gtk_window_set_icon_list(). The list is copied, but the reference count on each member won't be incremented.

String childname Required (not null)

Returns:

GObject.Object

Returns whether this embed container is a popup.

Returns:

Boolean

Whether the widget is mapped.

Returns:

Boolean

Returns the mnemonic modifier for this window. See gtk_window_set_mnemonic_modifier(). mnemonics on this window.

Returns:

Gdk.ModifierType

Returns:

Boolean

Returns whether the window is modal. See gtk_window_set_modal(). establishes a grab when shown

Returns:

Boolean

Returns the current modifier style for the widget. (As set by gtk_widget_modify_style().) If no style has previously set, a new GtkRcStyle will be created with all values unset, and set as the modifier style for the widget. If you make changes to this rc style, you must call gtk_widget_modify_style(), passing in the returned rc style, to make sure that your changes take effect. normally end up destroying it, because gtk_widget_modify_style() copies the passed-in style and sets the copy as the new modifier style, thus dropping any reference to the old modifier style. Add a reference to the modifier style if you want to keep it alive. owned by the widget. If you want to keep a pointer to value this around, you must add a refcount using g_object_ref().

Returns:

Gtk.RcStyle the modifier style for the widget. This rc style is

Retrieves the name of a widget. See gtk_widget_set_name() for the significance of widget names. should not be modified or freed

Returns:

String

Returns the current value of the GtkWidget:no-show-all property, which determines whether calls to gtk_widget_show_all() and gtk_widget_hide_all() will affect this widget.

Returns:

Boolean

Fetches the requested opacity for this window. See gtk_window_set_opacity().

Returns:

Number

Gets a PangoContext with the appropriate font map, font description, and base direction for this widget. Unlike the context returned by gtk_widget_create_pango_context(), this context is owned by the widget (it can be used until the screen for the widget changes or the widget is removed from its toplevel), and will be updated to match any changes to the widget's attributes. If you create and keep a PangoLayout using this context, you must deal with changes to the context by calling pango_layout_context_changed() on the layout in response to the GtkWidget::style-set and GtkWidget::direction-changed signals for the widget.

Returns:

Pango.Context the PangoContext for the widget.

Returns the parent container of widget.

Returns:

Gtk.Widget the parent container of widget, or NULL

Gets widget's parent window.

Returns:

Gdk.Window the parent window of widget.

Obtains the location of the mouse pointer in widget coordinates. Widget coordinates are a bit odd; for historical reasons, they are defined as widget->window coordinates for widgets that are not GTK_NO_WINDOW widgets, and are relative to widget->allocation.x,

Returns:

x: Number

y: Number

This function returns the position you need to pass to gtk_window_move() to keep window in its current position. This means that the meaning of the returned value varies with window gravity. See gtk_window_move() for more details. If you haven't changed the window gravity, its gravity will be GDK_GRAVITY_NORTH_WEST. This means that gtk_window_get_position() gets the position of the top-left corner of the window manager frame for the window. gtk_window_move() sets the position of this same top-left corner. gtk_window_get_position() is not 100% reliable because the X Window System does not specify a way to obtain the geometry of the decorations placed on a window by the window manager. Thus GTK+ is using a "best guess" that works with most window managers. Moreover, nearly all window managers are historically broken with respect to their handling of window gravity. So moving a window to its current position as returned by gtk_window_get_position() tends to result in moving the window slightly. Window managers are slowly getting better over time. If a window has gravity GDK_GRAVITY_STATIC the window manager frame is not relevant, and thus gtk_window_get_position() will always produce accurate results. However you can't use static gravity to do things like place a window in a corner of the screen, because static gravity ignores the window manager decorations. If you are saving and restoring your application's window positions, you should know that it's impossible for applications to do this without getting it somewhat wrong because applications do not have sufficient knowledge of window manager state. The Correct Mechanism is to support the session management protocol (see the "GnomeClient" object in the GNOME libraries for example) and allow the window manager to save your window sizes and positions.

Returns:

root_x: Number

root_y: Number

Determines whether widget is realized.

Returns:

Boolean

Determines whether widget is alyways treated as default widget withing its toplevel when it has the focus, even if another widget is the default. See gtk_widget_set_receives_default(). FALSE otherwise

Returns:

Boolean

Retrieves the widget's requisition. This function should only be used by widget implementations in order to figure whether the widget's requisition has actually changed after some internal state change (so that they can call gtk_widget_queue_resize() instead of gtk_widget_queue_draw()). Normally, gtk_widget_size_request() should be used.

Returns:

Gtk.Requisition

Gets the value set by gtk_window_set_resizable().

Returns:

Boolean

Returns the resize mode for the container. See gtk_container_set_resize_mode ().

Returns:

Gtk.ResizeMode

Returns the role of the window. See gtk_window_set_role() for further explanation. returned is owned by the widget and must not be modified or freed.

Returns:

String

Get the root window where this widget is located. This function can only be called after the widget has been added to a widget hierarchy with GtkWindow at the top. The root window is useful for such purposes as creating a popup GdkWindow associated with the window. In general, you should only create display specific resources when a widget has been realized, and you should free those resources when the widget is unrealized.

Returns:

Gdk.Window the GdkWindow root window for the toplevel for this widget.

Returns:

Gdk.Screen

Returns the widget's sensitivity (in the sense of returning the value that has been set using gtk_widget_set_sensitive()). The effective sensitivity of a widget is however determined by both its own and its parent widget's sensitivity. See gtk_widget_is_sensitive().

Returns:

Boolean

Gets the settings object holding the settings (global property settings, RC file information, etc) used for this widget. Note that this function can only be called when the GtkWidget is attached to a toplevel, since the settings object is specific to a particular GdkScreen.

Returns:

Gtk.Settings the relevant GtkSettings object

Obtains the current size of window. If window is not onscreen, it returns the size GTK+ will suggest to the window manager for the initial window size (but this is not reliably the same as the size the window manager will actually select). The size obtained by gtk_window_get_size() is the last size received in a GdkEventConfigure, that is, GTK+ uses its locally-stored size, rather than querying the X server for the size. As a result, if you call gtk_window_resize() then immediately call gtk_window_get_size(), the size won't have taken effect yet. After the window manager processes the resize request, GTK+ receives notification that the size has changed via a configure event, and the size of the window gets updated. because the size of the window may change between the time that you get the size and the time that you perform some action assuming that size is the current size. To avoid race conditions, connect to "configure-event" on the window and adjust your size-dependent state to match the size delivered in the GdkEventConfigure. size of the window manager decorations (aka the window frame or border). Those are not drawn by GTK+ and GTK+ has no reliable method of determining their size. the window onscreen, there may be a better way. The preferred way is to simply set the window's semantic type with gtk_window_set_type_hint(), which allows the window manager to e.g. center dialogs. Also, if you set the transient parent of dialogs with gtk_window_set_transient_for() window managers will often center the dialog over its parent window. It's much preferred to let the window manager handle these things rather than doing it yourself, because all apps will behave consistently and according to user prefs if the window manager handles it. Also, the window manager can take the size of the window decorations/border into account, while your application cannot. In any case, if you insist on application-specified window positioning, there's still a better way than doing it yourself - gtk_window_set_position() will frequently handle the details for you.

Returns:

width: Number

height: Number

Gets the size request that was explicitly set for the widget using gtk_widget_set_size_request(). A value of -1 stored in width or and the natural requisition of the widget will be used intead. See gtk_widget_set_size_request(). To get the size a widget will actually use, call gtk_widget_size_request() instead of this function.

Returns:

width: Number

height: Number

Gets the value set by gtk_window_set_skip_pager_hint().

Returns:

Boolean

Gets the value set by gtk_window_set_skip_taskbar_hint()

Returns:

Boolean

Create a GdkPixmap of the contents of the widget and its children. Works even if the widget is obscured. The depth and visual of the resulting pixmap is dependent on the widget being snapshot and likely differs from those of a target widget displaying the pixmap. The function gdk_pixbuf_get_from_drawable() can be used to convert the pixmap to a visual independant representation. The snapshot area used by this function is the widget's allocation plus any extra space occupied by additional windows belonging to this widget (such as the arrows of a spin button). Thus, the resulting snapshot pixmap is possibly larger than the allocation. If clip_rect is non-NULL, the resulting pixmap is shrunken to match the specified clip_rect. The (x,y) coordinates of clip_rect are interpreted widget relative. If width or height of clip_rect are 0 or negative, the width or height of the resulting pixmap will be shrunken by the respective amount. For instance a clip_rect { +5, +5, -10, -10 } will chop off 5 pixels at each side of the snapshot pixmap. If non-NULL, clip_rect will contain the exact widget-relative snapshot coordinates upon return. A clip_rect of { -1, -1, 0, 0 } can be used to preserve the auto-grown snapshot area and use clip_rect as a pure output parameter. The returned pixmap can be NULL, if the resulting clip_area was empty.

Parameters:

Gdk.Rectangle clip_rect

a GdkRectangle or NULL

Returns:

Gdk.Pixmap

Returns the widget's state. See gtk_widget_set_state().

Returns:

Gtk.StateType

Simply an accessor function that returns widget->style.

Returns:

Gtk.Style the widget's GtkStyle

Retrieves the title of the window. See gtk_window_set_title(). been set explicitely. The returned string is owned by the widget and must not be modified or freed.

Returns:

String

Gets the contents of the tooltip for widget. returned string with g_free() when done.

Returns:

String

Gets the contents of the tooltip for widget. returned string with g_free() when done.

Returns:

String

Returns the GtkWindow of the current tooltip. This can be the GtkWindow created by default, or the custom tooltip window set using gtk_widget_set_tooltip_window().

Returns:

Gtk.Window The GtkWindow of the current tooltip.

This function returns the topmost widget in the container hierarchy returned as the topmost widget. No reference will be added to the returned widget; it should not be unreferenced. Note the difference in behavior vs. gtk_widget_get_ancestor(); gtk_widget_get_ancestor (widget, GTK_TYPE_WINDOW) would return NULL if widget wasn't inside a toplevel window, and if the window was inside a GtkWindow-derived widget which was in turn inside the toplevel GtkWindow. While the second case may seem unlikely, it actually happens when a GtkPlug is embedded inside a GtkSocket within the same application. To reliably find the toplevel GtkWindow, use gtk_widget_get_toplevel() and check if the TOPLEVEL flags is set on the result. |[ GtkWidget *toplevel = gtk_widget_get_toplevel (widget); if (gtk_widget_is_toplevel (toplevel)) { /* Perform action on toplevel. */ } ]| if there's no ancestor.

Returns:

Gtk.Widget the topmost ancestor of widget, or widget itself

Fetches the transient parent for this window. See gtk_window_set_transient_for(). if no transient parent has been set.

Returns:

Gtk.Window the transient parent for this window, or NULL

Gets the type hint for this window. See gtk_window_set_type_hint().

Returns:

Gdk.WindowTypeHint

Gets the value set by gtk_window_set_urgency_hint()

Returns:

Boolean

Returns:

void*

Determines whether the widget is visible. Note that this doesn't take into account whether the widget's parent is also visible or the widget is obscured in any way. See gtk_widget_set_visible().

Returns:

Boolean

Gets the visual that will be used to render widget.

Returns:

Gdk.Visual the visual for widget

Returns the widget's window if it is realized, NULL otherwise

Returns:

Gdk.Window

Gets the type of the window. See GtkWindowType.

Returns:

Gtk.WindowType

Causes widget to become the default widget. widget must have the GTK_CAN_DEFAULT flag set; typically you have to set this flag yourself by calling gtk_widget_set_can_default (widget, TRUE). The default widget is activated when the user presses Enter in a window. Default widgets must be activatable, that is, gtk_widget_activate() should affect them.

Returns:

none

Causes widget to have the keyboard focus for the GtkWindow it's inside. widget must be a focusable widget, such as a GtkEntry; something like GtkFrame won't work. More precisely, it must have the GTK_CAN_FOCUS flag set. Use gtk_widget_set_can_focus() to modify that flag.

Returns:

none

Determines whether widget is the current default widget within its toplevel. See gtk_widget_set_can_default(). its toplevel, FALSE otherwise

Returns:

Boolean

Determines if the widget has the global input focus. See gtk_widget_is_focus() for the difference between having the global input focus, and only having the focus within a toplevel.

Returns:

Boolean

Determines whether the widget is currently grabbing events, so it is the only widget receiving input events (keyboard and mouse). See also gtk_grab_add().

Returns:

Boolean

Determines if the widget style has been looked up through the rc mechanism. mechanism, FALSE otherwise.

Returns:

Boolean

Checks whether there is a GdkScreen is associated with this widget. All toplevel widgets have an associated screen, and all widgets added into a hierarchy with a toplevel window at the top. with the widget.

Returns:

Boolean

Returns whether the input focus is within this GtkWindow. For real toplevel windows, this is identical to gtk_window_is_active(), but for embedded windows, like GtkPlug, the results will differ.

Returns:

Boolean

Reverses the effects of gtk_widget_show(), causing the widget to be hidden (invisible to the user).

Returns:

none

Recursively hides a widget and any child widgets.

Returns:

none

Utility function; intended to be connected to the GtkWidget::delete-event signal on a GtkWindow. The function calls gtk_widget_hide() on its argument, then returns TRUE. If connected to ::delete-event, the result is that clicking the close button for a window (on the window frame, top right corner usually) will hide but not destroy the window. By default, GTK+ destroys windows when ::delete-event is received.

Returns:

Boolean

Asks to iconify (i.e. minimize) the specified window. Note that you shouldn't assume the window is definitely iconified afterward, because other entities (e.g. the user or window manager) could deiconify it again, or there may not be a window manager in which case iconification isn't possible, etc. But normally the window will end up iconified. Just don't write code that crashes if not. It's permitted to call this function before showing a window, in which case the window will be iconified before it ever appears onscreen. You can track iconification via the "window-state-event" signal on GtkWidget.

Returns:

none

Sets an input shape for this widget's GDK window. This allows for windows which react to mouse click in a nonrectangular region, see gdk_window_input_shape_combine_mask() for more information.

Parameters:

Gdk.Bitmap shape_mask

shape to be added, or NULL to remove an existing shape

Number offset_x Required (not null)

Number offset_y Required (not null)

Returns:

none

Computes the intersection of a widget's area and area, storing the intersection in intersection, and returns TRUE if there was an intersection. intersection may be NULL if you're only interested in whether there was an intersection.

Parameters:

Gdk.Rectangle area Required (not null)

Gdk.Rectangle intersection Required (not null)

Returns:

Boolean

Returns whether the window is part of the current active toplevel. (That is, the toplevel window receiving keystrokes.) The return value is TRUE if the window is active toplevel itself, but also if it is, say, a GtkPlug embedded in the active toplevel. You might use this function if you wanted to draw a widget differently in an active window from a widget in an inactive window. See gtk_window_has_toplevel_focus()

Returns:

Boolean

Determines whether widget is somewhere inside ancestor, possibly with intermediate containers. grandchild, great grandchild, etc.

Parameters:

Gtk.Widget ancestor Required (not null)

Returns:

Boolean

Whether widget can rely on having its alpha channel drawn correctly. On X11 this function returns whether a compositing manager is running for widget's screen. Please note that the semantics of this call will change in the future if used on a widget that has a composited window in its hierarchy (as set by gdk_window_set_composited()). channel being drawn correctly.

Returns:

Boolean

Determines whether widget can be drawn to. A widget can be drawn to if it is mapped and visible.

Returns:

Boolean

Determines if the widget is the focus widget within its toplevel. (This does not mean that the HAS_FOCUS flag is necessarily set; HAS_FOCUS will only be set if the toplevel widget additionally has the global input focus.)

Returns:

Boolean

Returns the widget's effective sensitivity, which means it is sensitive itself and also its parent widget is sensntive

Returns:

Boolean

Determines whether widget is a toplevel widget. Currently only GtkWindow and GtkInvisible are toplevel widgets. Toplevel widgets have no parent widget.

Returns:

Boolean

This function should be called whenever keyboard navigation within a single widget hits a boundary. The function emits the GtkWidget::keynav-failed signal on the widget and its return value should be interpreted in a way similar to the return value of gtk_widget_child_focus(): When TRUE is returned, stay in the widget, the failed keyboard navigation is Ok and/or there is nowhere we can/should move the focus to. When FALSE is returned, the caller should continue with keyboard navigation outside the widget, e.g. by calling gtk_widget_child_focus() on the widget's toplevel. The default ::keynav-failed handler returns TRUE for GTK_DIR_TAB_FORWARD and GTK_DIR_TAB_BACKWARD. For the other values of GtkDirectionType, it looks at the GtkSettings:gtk-keynav-cursor-only setting and returns FALSE if the setting is TRUE. This way the entire user interface becomes cursor-navigatable on input devices such as mobile phones which only have cursor keys but no tab key. Whenever the default handler returns TRUE, it also calls gtk_widget_error_bell() to notify the user of the failed keyboard navigation. A use case for providing an own implementation of ::keynav-failed (either by connecting to it or by overriding it) would be a row of GtkEntry widgets where the user should be able to navigate the entire row with the cursor keys, as e.g. known from user interfaces that require entering license keys. if the emitting widget should try to handle the keyboard navigation attempt in its parent container(s).

Parameters:

Gtk.DirectionType direction Required (not null)

Returns:

Boolean

Returns a newly allocated list of the widgets, normally labels, for which this widget is a the target of a mnemonic (see for example, gtk_label_set_mnemonic_widget()). The widgets in the list are not individually referenced. If you want to iterate through the list and perform actions involving callbacks that might destroy the widgets, you must call g_list_foreach (result, (GFunc)g_object_ref, NULL) first, and then unref all the widgets afterwards. mnemonic labels; free this list with g_list_free() when you are done with it.

Returns:

Array the list of

This function is only for use in widget implementations. Causes a widget to be mapped if it isn't already.

Returns:

none

Asks to maximize window, so that it becomes full-screen. Note that you shouldn't assume the window is definitely maximized afterward, because other entities (e.g. the user or window manager) could unmaximize it again, and not all window managers support maximization. But normally the window will end up maximized. Just don't write code that crashes if not. It's permitted to call this function before showing a window, in which case the window will be maximized when it appears onscreen initially. You can track maximization via the "window-state-event" signal on GtkWidget.

Returns:

none

Activates the targets associated with the mnemonic.

Parameters:

Number keyval Required (not null)

Gdk.ModifierType modifier Required (not null)

Returns:

Boolean

Sets the base color for a widget in a particular state. All other style values are left untouched. The base color is the background color used along with the text color (see gtk_widget_modify_text()) for widgets such as GtkEntry and GtkTextView. See also gtk_widget_modify_style(). Note that "no window" widgets (which have the GTK_NO_WINDOW flag set) draw on their parent container's window and thus may not draw any background themselves. This is the case for e.g. GtkLabel. To modify the background of such widgets, you have to set the base color on their parent; if you want to set the background of a rectangular area around a label, try placing the label in a GtkEventBox widget and setting the base color on that.

Parameters:

Gtk.StateType state Required (not null)

Gdk.Color color

or NULL to undo the effect of previous calls to of gtk_widget_modify_base().

Returns:

none

Sets the background color for a widget in a particular state. All other style values are left untouched. See also gtk_widget_modify_style(). Note that "no window" widgets (which have the GTK_NO_WINDOW flag set) draw on their parent container's window and thus may not draw any background themselves. This is the case for e.g. GtkLabel. To modify the background of such widgets, you have to set the background color on their parent; if you want to set the background of a rectangular area around a label, try placing the label in a GtkEventBox widget and setting the background color on that.

Parameters:

Gtk.StateType state Required (not null)

Gdk.Color color

or NULL to undo the effect of previous calls to of gtk_widget_modify_bg().

Returns:

none

Sets the cursor color to use in a widget, overriding the GtkWidget:cursor-color and GtkWidget:secondary-cursor-color style properties. All other style values are left untouched. See also gtk_widget_modify_style().

Parameters:

Gdk.Color primary Required (not null)

allocated), or NULL to undo the effect of previous calls to of gtk_widget_modify_cursor().

Gdk.Color secondary Required (not null)

allocated), or NULL to undo the effect of previous calls to of gtk_widget_modify_cursor().

Returns:

none

Sets the foreground color for a widget in a particular state. All other style values are left untouched. See also gtk_widget_modify_style().

Parameters:

Gtk.StateType state Required (not null)

Gdk.Color color

or NULL to undo the effect of previous calls to of gtk_widget_modify_fg().

Returns:

none

Sets the font to use for a widget. All other style values are left untouched. See also gtk_widget_modify_style().

Parameters:

Pango.FontDescription font_desc

the font description to use, or NULL to undo the effect of previous calls to gtk_widget_modify_font().

Returns:

none

Modifies style values on the widget. Modifications made using this technique take precedence over style values set via an RC file, however, they will be overriden if a style is explicitely set on the widget using gtk_widget_set_style(). The GtkRcStyle structure is designed so each field can either be set or unset, so it is possible, using this function, to modify some style values and leave the others unchanged. Note that modifications made with this function are not cumulative with previous calls to gtk_widget_modify_style() or with such functions as gtk_widget_modify_fg(). If you wish to retain previous values, you must first call gtk_widget_get_modifier_style(), make your modifications to the returned style, then call gtk_widget_modify_style() with that style. On the other hand, if you first call gtk_widget_modify_style(), subsequent calls to such functions gtk_widget_modify_fg() will have a cumulative effect with the initial modifications.

Parameters:

Gtk.RcStyle style Required (not null)

Returns:

none

Sets the text color for a widget in a particular state. All other style values are left untouched. The text color is the foreground color used along with the base color (see gtk_widget_modify_base()) for widgets such as GtkEntry and GtkTextView. See also gtk_widget_modify_style().

Parameters:

Gtk.StateType state Required (not null)

Gdk.Color color

or NULL to undo the effect of previous calls to of gtk_widget_modify_text().

Returns:

none

Asks the window manager to move this; most window managers ignore requests for initial window positions (instead using a user-defined placement algorithm) and honor requests after the window has already been shown. reference point for the window. The gravity determines two things: first, the location of the reference point in root window coordinates; and second, which point on the window is positioned at the reference point. By default the gravity is GDK_GRAVITY_NORTH_WEST, so the reference point is simply the x, y supplied to gtk_window_move(). The top-left corner of the window decorations (aka window frame or border) will be placed at x, y. Therefore, to position a window at the top left of the screen, you want to use the default gravity (which is GDK_GRAVITY_NORTH_WEST) and move the window to 0,0. To position a window at the bottom right corner of the screen, you would set GDK_GRAVITY_SOUTH_EAST, which means that the reference point is at x + the window width and y + the window height, and the bottom-right corner of the window border will be placed at that reference point. So, to place a window in the bottom right corner you would first set gravity to south east, then write: gtk_window_move (window, gdk_screen_width () - window_width, gdk_screen_height () - window_height) (note that this example does not take multi-head scenarios into account). The Extended Window Manager Hints specification at http://www.freedesktop.org/Standards/wm-spec has a nice table of gravities in the "implementation notes" section. The gtk_window_get_position() documentation may also be relevant.

Parameters:

Number x Required (not null)

Number y Required (not null)

Returns:

none

Parameters:

String address Required (not null)

Epiphany.EphyEmbed embed Required (not null)

Epiphany.EphyLinkFlags flags Required (not null)

Returns:

Epiphany.EphyEmbed

Parses a standard X Window System geometry string - see the manual page for X (type 'man X') for details on this. gtk_window_parse_geometry() does work on all GTK+ ports including Win32 but is primarily intended for an X environment. If either a size or a position can be extracted from the geometry string, gtk_window_parse_geometry() returns TRUE and calls gtk_window_set_default_size() and/or gtk_window_move() to resize/move the window. If gtk_window_parse_geometry() returns TRUE, it will also set the GDK_HINT_USER_POS and/or GDK_HINT_USER_SIZE hints indicating to the window manager that the size/position of the window was user-specified. This causes most window managers to honor the geometry. Note that for gtk_window_parse_geometry() to work as expected, it has to be called when the window has its "final" size, i.e. after calling gtk_widget_show_all() on the contents and gtk_window_set_geometry_hints() on the window. |[ include static void fill_with_content (GtkWidget *vbox) { /* fill with content... */ } int main (int argc, char *argv[]) { GtkWidget *window, *vbox; GdkGeometry size_hints = { 100, 50, 0, 0, 100, 50, 10, 10, 0.0, 0.0, GDK_GRAVITY_NORTH_WEST }; gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); vbox = gtk_vbox_new (FALSE, 0); gtk_container_add (GTK_CONTAINER (window), vbox); fill_with_content (vbox); gtk_widget_show_all (vbox); gtk_window_set_geometry_hints (GTK_WINDOW (window), window, &size_hints, GDK_HINT_MIN_SIZE | GDK_HINT_BASE_SIZE | GDK_HINT_RESIZE_INC); if (argc > 1) { if (!gtk_window_parse_geometry (GTK_WINDOW (window), argv[1])) fprintf (stderr, "Failed to parse 's'\n", argv[1]); } gtk_widget_show_all (window); gtk_main (); return 0; } ]|

Parameters:

String geometry Required (not null)

Returns:

Boolean

Called when the builder finishes the parsing of a GtkBuilder UI definition. Note that this will be called once for each time gtk_builder_add_from_file() or gtk_builder_add_from_string() is called on a builder.

Parameters:

Gtk.Builder builder Required (not null)

Returns:

none

Obtains the full path to widget. The path is simply the name of a widget and all its parents in the container hierarchy, separated by periods. The name of a widget comes from gtk_widget_get_name(). Paths are used to apply styles to a widget in gtkrc configuration files. Widget names are the type of the widget by default (e.g. "GtkButton") or can be set to an application-specific value with gtk_widget_set_name(). By setting the name of a widget, you allow users or theme authors to apply styles to that specific widget in their gtkrc file. path_reversed_p fills in the path in reverse order, i.e. starting with widget's name instead of starting with the name of widget's outermost ancestor.

Returns:

path_length: Number

path: String

path_reversed: String

Presents a window to the user. This may mean raising the window in the stacking order, deiconifying it, moving it to the current desktop, and/or giving it the keyboard focus, possibly dependent on the user's platform, window manager, and preferences. If window is hidden, this function calls gtk_widget_show() as well. This function should be used when the user tries to open a window that's already open. Say for example the preferences dialog is currently open, and the user chooses Preferences from the menu a second time; use gtk_window_present() to move the already-open dialog where the user can see it. If you are calling this function in response to a user interaction, it is preferable to use gtk_window_present_with_time().

Returns:

none

Presents a window to the user in response to a user interaction. If you need to present a window without a timestamp, use gtk_window_present(). See gtk_window_present() for details.

Parameters:

Number timestamp Required (not null)

button or key press event) which triggered this call

Returns:

none

When a container receives an expose event, it must send synthetic expose events to all children that don't have their own GdkWindows. This function provides a convenient way of doing this. A container, when it receives an expose event, calls gtk_container_propagate_expose() once for each child, passing in the event the container received. gtk_container_propagate_expose() takes care of deciding whether an expose event needs to be sent to the child, intersecting the event's area with the child area, and sending the event. In most cases, a container can simply either simply inherit the GtkWidget::expose implementation from GtkContainer, or, do some drawing and then chain to the ::expose implementation from GtkContainer.

Parameters:

Gtk.Widget child Required (not null)

Gdk.EventExpose event Required (not null)

Returns:

none

Propagate a key press or release event to the focus widget and up the focus container chain until a widget handles event. This is normally called by the default ::key_press_event and ::key_release_event handlers for toplevel windows, however in some cases it may be useful to call this directly when overriding the standard key handling for a toplevel window.

Parameters:

Gdk.EventKey event Required (not null)

Returns:

Boolean

This function does the same as gtk_widget_queue_draw().

Returns:

none

This function is no longer different from gtk_widget_queue_draw_area(), though it once was. Now it just calls gtk_widget_queue_draw_area(). Originally gtk_widget_queue_clear_area() would force a redraw of the background for GTK_NO_WINDOW widgets, and gtk_widget_queue_draw_area() would not. Now both functions ensure the background will be redrawn.

Parameters:

Number x Required (not null)

Number y Required (not null)

Number width Required (not null)

Number height Required (not null)

Returns:

none

Equivalent to calling gtk_widget_queue_draw_area() for the entire area of a widget.

Returns:

none

Invalidates the rectangular area of widget defined by x, y, widget's window and all its child windows. Once the main loop becomes idle (after the current batch of events has been processed, roughly), the window will receive expose events for the union of all regions that have been invalidated. Normally you would only use this function in widget implementations. You might also use it, or gdk_window_invalidate_rect() directly, to schedule a redraw of a GtkDrawingArea or some portion thereof. Frequently you can just call gdk_window_invalidate_rect() or gdk_window_invalidate_region() instead of this function. Those functions will invalidate only a single window, instead of the widget and all its children. The advantage of adding to the invalidated region compared to simply drawing immediately is efficiency; using an invalid region ensures that you only have to redraw one time.

Parameters:

Number x Required (not null)

Number y Required (not null)

Number width Required (not null)

Number height Required (not null)

Returns:

none

This function is only for use in widget implementations. Flags a widget to have its size renegotiated; should be called when a widget for some reason has a new size request. For example, when you change the text in a GtkLabel, GtkLabel queues a resize to ensure there's enough space for the new text.

Returns:

none

This function works like gtk_widget_queue_resize(), except that the widget is not invalidated.

Returns:

none

Creates the GDK (windowing system) resources associated with a widget. For example, widget->window will be created when a widget is realized. Normally realization happens implicitly; if you show a widget and all its parent containers, then the widget will be realized and mapped automatically. Realizing a widget requires all the widget's parent widgets to be realized; calling gtk_widget_realize() realizes the widget's parents in addition to when you realize it, bad things will happen. This function is primarily used in widget implementations, and isn't very useful otherwise. Many times when you think you might need it, a better approach is to connect to a signal that will be called after the widget is realized automatically, such as GtkWidget::expose-event. Or simply g_signal_connect () to the GtkWidget::realize signal.

Returns:

none

Gets a reference to an object's AtkObject implementation, if the object implements AtkObjectIface

Returns:

Atk.Object

Computes the intersection of a widget's area and region, returning the intersection. The result may be empty, use gdk_region_empty() to check.

Parameters:

Gdk.Region region Required (not null)

Returns:

Gdk.Region and region. The coordinates of the return value are relative to widget->window for NO_WINDOW widgets, and relative to the parent window of widget->window for widgets with their own window.

Removes widget from container. widget must be inside container. Note that container will own a reference to widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use widget again, you need to add a reference to it while it's not inside a container, using g_object_ref(). If you don't want to use widget again it's usually more efficient to simply destroy it directly using gtk_widget_destroy() since this will remove it from the container and help break any circular reference count cycles.

Parameters:

Gtk.Widget widget Required (not null)

Returns:

none

Reverses the effects of gtk_window_add_accel_group().

Parameters:

Gtk.AccelGroup accel_group Required (not null)

Returns:

none

Removes an accelerator from widget, previously installed with gtk_widget_add_accelerator().

Parameters:

Gtk.AccelGroup accel_group Required (not null)

Number accel_key Required (not null)

Gdk.ModifierType accel_mods Required (not null)

Returns:

Boolean

Removes child from container.

Parameters:

Epiphany.EphyEmbed child Required (not null)

Returns:

none

Parameters:

String key Required (not null)

Returns:

none

Parameters:

Number data_id Required (not null)

Returns:

none

Parameters:

Number xid Required (not null)

Returns:

none

Removes a mnemonic from this window.

Parameters:

Number keyval Required (not null)

Gtk.Widget target Required (not null)

Returns:

none

Removes a widget from the list of mnemonic labels for this widget. (See gtk_widget_list_mnemonic_labels()). The widget must have previously been added to the list with gtk_widget_add_mnemonic_label().

Parameters:

Gtk.Widget label Required (not null)

Returns:

none

Parameters:

String key Required (not null)

Returns:

none

Parameters:

Number key_id Required (not null)

Returns:

none

A convenience function that uses the theme engine and RC file settings for widget to look up stock_id and render it to a pixbuf. stock_id should be a stock icon ID such as GTK_STOCK_OPEN or GTK_STOCK_OK. size should be a size such as GTK_ICON_SIZE_MENU. detail should be a string that identifies the widget or code doing the rendering, so that theme engines can special-case rendering for that widget or code. The pixels in the returned GdkPixbuf are shared with the rest of the application and should not be modified. The pixbuf should be freed after use with g_object_unref().

Parameters:

String stock_id Required (not null)

Number size Required (not null)

1 means render at the size of the source and don't scale (if there are multiple source sizes, GTK+ picks one of the available sizes).

String detail

render detail to pass to theme engine

Returns:

GdkPixbuf.Pixbuf

Moves a widget from one GtkContainer to another, handling reference count issues to avoid destroying the widget.

Parameters:

Gtk.Widget new_parent Required (not null)

Returns:

none

Reset the styles of widget and all descendents, so when they are looked up again, they get the correct values for the currently loaded RC file settings. This function is not useful for applications.

Returns:

none

Recursively resets the shape on this widget and its descendants.

Returns:

none

Hides window, then reshows it, resetting the default size and position of the window. Used by GUI builders only.

Returns:

none

Resizes the window as if the user had done so, obeying geometry constraints. The default geometry constraint is that windows may not be smaller than their size request; to override this constraint, call gtk_widget_set_size_request() to set the window's request to a smaller value. If gtk_window_resize() is called before showing a window for the first time, it overrides any default size set with gtk_window_set_default_size(). Windows may not be resized smaller than 1 by 1 pixels.

Parameters:

Number width Required (not null)

Number height Required (not null)

Returns:

none

Returns:

none

Very rarely-used function. This function is used to emit an expose event signals on a widget. This function is not normally used directly. The only time it is used is when propagating an expose event to a child NO_WINDOW widget, and that is normally done using gtk_container_propagate_expose(). If you want to force an area of a window to be redrawn, use gdk_window_invalidate_rect() or gdk_window_invalidate_region(). To cause the redraw to be done immediately, follow that call with a call to gdk_window_process_updates(). the event was handled)

Parameters:

Gdk.Event event Required (not null)

Returns:

Number

Sends the focus change event to widget This function is not meant to be used by applications. The only time it should be used is when it is necessary for a GtkWidget to assign focus to a widget that is semantically owned by the first widget even though it's not a direct child - for instance, a search entry in a floating window similar to the quick search in GtkTreeView. An example of its usage is: |[ GdkEvent *fevent = gdk_event_new (GDK_FOCUS_CHANGE); fevent->focus_change.type = GDK_FOCUS_CHANGE; fevent->focus_change.in = TRUE; fevent->focus_change.window = gtk_widget_get_window (widget); if (fevent->focus_change.window != NULL) g_object_ref (fevent->focus_change.window); gtk_widget_send_focus_change (widget, fevent); gdk_event_free (event); ]| if the event was handled, and FALSE otherwise

Parameters:

Gdk.Event event Required (not null)

Returns:

Boolean

Given an accelerator group, accel_group, and an accelerator path, key binding that is defined for accel_path is pressed, widget will be activated. This removes any accelerators (for any accelerator group) installed by previous calls to gtk_widget_set_accel_path(). Associating accelerators with paths allows them to be modified by the user and the modifications to be saved for future use. (See gtk_accel_map_save().) This function is a low level function that would most likely be used by a menu creation system like GtkUIManager. If you use GtkUIManager, setting up accelerator paths will be done automatically. Even when you you aren't using GtkUIManager, if you only want to set up accelerators on menu items gtk_menu_item_set_accel_path() provides a somewhat more convenient interface. Note that accel_path string will be stored in a GQuark. Therefore, if you pass a static string, you can save some memory by interning it first with g_intern_static_string().

Parameters:

String accel_path

path used to look up the accelerator

Gtk.AccelGroup accel_group

a GtkAccelGroup.

Returns:

none

Windows may set a hint asking the desktop environment not to receive the input focus. This function sets this hint.

Parameters:

Boolean setting Required (not null)

Returns:

none

Sets child as container's active child.

Parameters:

Epiphany.EphyEmbed child Required (not null)

Returns:

none

Sets the widget's allocation. This should not be used directly, but from within a widget's size_allocate method.

Parameters:

Gdk.Rectangle allocation Required (not null)

Returns:

none

Sets whether the application intends to draw on the widget in an GtkWidget::expose-event handler. This is a hint to the widget and does not affect the behavior of the GTK+ core; many widgets ignore this flag entirely. For widgets that do pay attention to the flag, such as GtkEventBox and GtkWindow, the effect is to suppress default themed drawing of the widget's background. (Children of the widget will still be drawn.) The application is then entirely responsible for drawing the widget background. Note that the background is still drawn when the widget is mapped. If this is not suitable (e.g. because you want to make a transparent window using an RGBA visual), you can work around this by doing: |[ gtk_widget_realize (window); gdk_window_set_back_pixmap (window->window, NULL, FALSE); gtk_widget_show (window); ]|

Parameters:

Boolean app_paintable Required (not null)

Returns:

none

Sets the border width of the container. The border width of a container is the amount of space to leave around the outside of the container. The only exception to this is GtkWindow; because toplevel windows can't leave space outside, they leave the space inside. The border is added on all sides of the container. To add space to only one side, one approach is to create a GtkAlignment widget, call gtk_widget_set_size_request() to give it a size, and place it on the side of the container as a spacer.

Parameters:

Number border_width Required (not null)

the container. Valid values are in the range 0-65535 pixels.

Returns:

none

Sets the property name name to value on the buildable object.

Parameters:

Gtk.Builder builder Required (not null)

String name Required (not null)

GObject.Value value Required (not null)

Returns:

none

Specifies whether widget can be a default widget. See gtk_widget_grab_default() for details about the meaning of "default".

Parameters:

Boolean can_default Required (not null)

Returns:

none

Specifies whether widget can own the input focus. See gtk_widget_grab_focus() for actually setting the input focus on a widget.

Parameters:

Boolean can_focus Required (not null)

Returns:

none

Sets whether widget should be mapped along with its when its parent is mapped and widget has been shown with gtk_widget_show(). The child visibility can be set for widget before it is added to a container with gtk_widget_set_parent(), to avoid mapping children unnecessary before immediately unmapping them. However it will be reset to its default state of TRUE when the widget is removed from a container. Note that changing the child visibility of a widget does not queue a resize on the widget. Most of the time, the size of a widget is computed from all visible children, whether or not they are mapped. If this is not the case, the container can queue a resize itself. This function is only useful for container implementations and never should be called by an application.

Parameters:

Boolean is_visible Required (not null)

Returns:

none

Sets the colormap for the widget to the given value. Widget must not have been previously realized. This probably should only be used from an init() function (i.e. from the constructor for the widget).

Parameters:

Gdk.Colormap colormap Required (not null)

Returns:

none

Sets a widgets composite name. The widget must be a composite child of its parent; see gtk_widget_push_composite_child().

Parameters:

String name Required (not null)

Returns:

none

Parameters:

String key Required (not null)

void* data Required (not null)

Returns:

none

Parameters:

Number data_id Required (not null)

void* data Required (not null)

Returns:

none

Parameters:

Number data_id Required (not null)

void* data Required (not null)

Function (void* data) : none Required (not null)

Returns:

none
