Interface Gtk.Editable

Import line:	Gtk = imports.gi.Gtk;
GIR File:	Gtk-3.0.gir
C documentation:	GtkEditable
Interface :	Editable
Implementations:	GWeather.LocationEntry, Gtk.Entry, Gtk.SpinButton

The GtkEditable interface is an interface which should be implemented by
text editing widgets, such as GtkEntry and GtkText. It contains functions
for generically manipulating an editable widget, a large number of action
signals used for key bindings, and several signals that an application can
connect to to modify the behavior of a widget.
As an example of the latter usage, by connecting
the following handler to "insert_text", an application
can convert all entry into a widget into uppercase.

Forcing entry to uppercase.

Methods / Constructors
Method / Constructor		Defined By
	copy_clipboard () : none Copies the contents of the currently selected content in the editable and puts it on the clipboard. Copies the contents of the currently selected content in the editable and puts it on the clipboard. Returns: none	Gtk.Editable
	cut_clipboard () : none Removes the contents of the currently selected content in the editable and puts it on the clipboard. Removes the contents of the currently selected content in the editable and puts it on the clipboard. Returns: none	Gtk.Editable
	delete_selection () : none Deletes the currently selected text of the editable. Deletes the currently selected text of the editable. This call doesn't do anything if there is no selected text. Returns: none	Gtk.Editable
	delete_text (gint32 *start_pos, gint32 end_pos) : none Deletes a sequence of characters. Deletes a sequence of characters. The characters that are deleted are those characters at positions from start_pos* up to, but not including are those from start_pos to the end of the text. Note that the positions are specified in characters, not bytes. Parameters: gint32 start_pos Required (not null) start position gint32 end_pos Required (not null) end position Returns: none	Gtk.Editable
	get_chars (gint32 *start_pos, gint32 end_pos) : String Retrieves a sequence of characters. Retrieves a sequence of characters. The characters that are retrieved are those characters at positions from start_pos* up to, but not including end_pos. If end_pos is negative, then the the characters retrieved are those characters from start_pos to the end of the text. Note that positions are specified in characters, not bytes. string. This string is allocated by the GtkEditable implementation and should be freed by the caller. Parameters: gint32 start_pos Required (not null) start of text gint32 end_pos Required (not null) end of text Returns: String a pointer to the contents of the widget as a	Gtk.Editable
	get_editable () : gboolean Retrieves whether editable is editable. Retrieves whether editable is editable. See gtk_editable_set_editable(). Returns: gboolean TRUE if editable is editable.	Gtk.Editable
	get_position () : gint32 Retrieves the current position of the cursor relative to the start of the content of the editable. Retrieves the current position of the cursor relative to the start of the content of the editable. Note that this position is in characters, not in bytes. Returns: gint32 the cursor position	Gtk.Editable
	get_selection_bounds (Object *out_values) : gboolean Retrieves the selection bound of the editable. Retrieves the selection bound of the editable. start_pos will be filled with the start of the selection and end_pos* with end. If no text was selected both will be identical and FALSE will be returned. Note that positions are specified in characters, not bytes. Parameters: Object out_values gint32 start_pos gint32 end_pos Returns: gboolean TRUE if an area is selected, FALSE otherwise	Gtk.Editable
	insert_text (String *new_text, gint32 new_text_length, gint32 position) : none Inserts new_text_length* bytes of new_text into the contents of the widget, at position position. Inserts new_text_length bytes of new_text into the contents of the widget, at position position. Note that the position is in characters, not in bytes. The function updates position to point after the newly inserted text. Parameters: String new_text Required (not null) the text to append gint32 new_text_length Required (not null) the length of the text in bytes, or -1 gint32 position Required (not null) location of the position text will be inserted at Returns: none	Gtk.Editable
	paste_clipboard () : none Pastes the content of the clipboard to the current position of the cursor in the editable. Pastes the content of the clipboard to the current position of the cursor in the editable. Returns: none	Gtk.Editable
	select_region (gint32 *start_pos, gint32 end_pos) : none Selects a region of text. Selects a region of text. The characters that are selected are those characters at positions from start_pos* up to, but not including end_pos. If end_pos is negative, then the the characters selected are those characters from start_pos to the end of the text. Note that positions are specified in characters, not bytes. Parameters: gint32 start_pos Required (not null) start of region gint32 end_pos Required (not null) end of region Returns: none	Gtk.Editable
	set_editable (gboolean *is_editable) : none Determines if the user can edit the text in the editable widget or not. Determines if the user can edit the text in the editable widget or not. Parameters: gboolean is_editable* Required (not null) TRUE if the user is allowed to edit the text in the widget Returns: none	Gtk.Editable
	set_position (gint32 *position) : none Sets the cursor position in the editable to the given value. Sets the cursor position in the editable to the given value. The cursor is displayed before the character with the given (base 0) index in the contents of the editable. The value must be less than or equal to the number of characters in the editable. A value of -1 indicates that the position should be set after the last character of the editable. Note that position* is in characters, not in bytes. Parameters: gint32 position Required (not null) the position of the cursor Returns: none	Gtk.Editable

Events - usage syntax: this.signals.EVENTNAME.connect( Function )
Event		Defined By
	changed (Editable *self) : none The ::changed signal is emitted at the end of a single user-visible operation on the contents of the GtkEditable. The ::changed signal is emitted at the end of a single user-visible operation on the contents of the GtkEditable. E.g., a paste operation that replaces the contents of the selection will cause only one signal emission (even though it is implemented by first deleting the selection, then inserting the new content, and may cause multiple ::notify::text signals to be emitted). Parameters: Gtk.Editable self* Returns: {none}	Gtk.Editable
	delete_text (Editable *self, gint32 start_pos, gint32 end_pos) : none This signal is emitted when text is deleted from the widget by the user. This signal is emitted when text is deleted from the widget by the user. The default handler for this signal will normally be responsible for deleting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the range of deleted text, or prevent it from being deleted entirely. The start_pos* and end_pos parameters are interpreted as for gtk_editable_delete_text(). Parameters: Gtk.Editable self gint32 start_pos gint32 end_pos Returns: {none}	Gtk.Editable
	insert_text (Editable *self, String new_text, gint32 new_text_length, gint32 position) : none This signal is emitted when text is inserted into the widget by the user. This signal is emitted when text is inserted into the widget by the user. The default handler for this signal will normally be responsible for inserting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the inserted text, or prevent it from being inserted entirely. Parameters: Gtk.Editable self* String new_text gint32 new_text_length gint32 position Returns: {none}	Gtk.Editable
