Properties
Properties		Defined By
	allow_async : Boolean Determines whether the print operation may run asynchronously or not. Determines whether the print operation may run asynchronously or not. Some systems don't support asynchronous printing, but those that do will return GTK_PRINT_OPERATION_RESULT_IN_PROGRESS as the status, and emit the GtkPrintOperation::done signal when the operation is actually done. The Windows port does not support asynchronous operation at all (this is unlikely to change). On other platforms, all actions except for GTK_PRINT_OPERATION_ACTION_EXPORT support asynchronous operation.	Gtk.PrintOperation
	current_page : Number The current page in the document. The current page in the document. If this is set before gtk_print_operation_run(), the user will be able to select to print only the current page. Note that this only makes sense for pre-paginated documents.	Gtk.PrintOperation
	custom_tab_label : String Used as the label of the tab containing custom widgets. Used as the label of the tab containing custom widgets. Note that this property may be ignored on some platforms. If this is NULL, GTK+ uses a default label.	Gtk.PrintOperation
	default_page_setup : Gtk.PageSetup The GtkPageSetup used by default. The GtkPageSetup used by default. This page setup will be used by gtk_print_operation_run(), but it can be overridden on a per-page basis by connecting to the GtkPrintOperation::request-page-setup signal.	Gtk.PrintOperation
	embed_page_setup : Boolean If TRUE, page size combo box and orientation combo box are embedded into page setup page. If TRUE, page size combo box and orientation combo box are embedded into page setup page.	Gtk.PrintOperation
	export_filename : String The name of a file to generate instead of showing the print dialog. The name of a file to generate instead of showing the print dialog. Currently, PDF is the only supported format. The intended use of this property is for implementing "Export to PDF" actions. "Print to PDF" support is independent of this and is done by letting the user pick the "Print to PDF" item from the list of printers in the print dialog.	Gtk.PrintOperation
	has_selection : Boolean Determines whether there is a selection in your application. Determines whether there is a selection in your application. This can allow your application to print the selection. This is typically used to make a "Selection" button sensitive.	Gtk.PrintOperation
	job_name : String A string used to identify the job (e.g. A string used to identify the job (e.g. in monitoring applications like eggcups). If you don't set a job name, GTK+ picks a default one by numbering successive print jobs.	Gtk.PrintOperation
	n_pages : Number The number of pages in the document. The number of pages in the document. This must be set to a positive number before the rendering starts. It may be set in a GtkPrintOperation::begin-print signal hander. Note that the page numbers passed to the GtkPrintOperation::request-page-setup and GtkPrintOperation::draw-page signals are 0-based, i.e. if the user chooses to print all pages, the last ::draw-page signal will be for page n_pages - 1.	Gtk.PrintOperation
	n_pages_to_print : Number read only The number of pages that will be printed. The number of pages that will be printed. Note that this value is set during print preparation phase (GTK_PRINT_STATUS_PREPARING), so this value should never be get before the data generation phase (GTK_PRINT_STATUS_GENERATING_DATA). You can connect to the GtkPrintOperation::status-changed signal and call gtk_print_operation_get_n_pages_to_print() when print status is GTK_PRINT_STATUS_GENERATING_DATA. This is typically used to track the progress of print operation.	Gtk.PrintOperation
	parent_instance : GObject.Object read only	Gtk.PrintOperation
	print_settings : Gtk.PrintSettings The GtkPrintSettings used for initializing the dialog. The GtkPrintSettings used for initializing the dialog. Setting this property is typically used to re-establish print settings from a previous print operation, see gtk_print_operation_run().	Gtk.PrintOperation
	priv : Gtk.PrintOperationPrivate read only	Gtk.PrintOperation
	show_progress : Boolean Determines whether to show a progress dialog during the print operation. Determines whether to show a progress dialog during the print operation.	Gtk.PrintOperation
	status : Gtk.PrintStatus read only The status of the print operation. The status of the print operation.	Gtk.PrintOperation
	status_string : String read only A string representation of the status of the print operation. A string representation of the status of the print operation. The string is translated and suitable for displaying the print status e.g. in a GtkStatusbar. See the GtkPrintOperation:status property for a status value that is suitable for programmatic use.	Gtk.PrintOperation
	support_selection : Boolean If TRUE, the print operation will support print of selection. If TRUE, the print operation will support print of selection. This allows the print dialog to show a "Selection" button.	Gtk.PrintOperation
	track_print_status : Boolean If TRUE, the print operation will try to continue report on the status of the print job in the printer queues and printer. If TRUE, the print operation will try to continue report on the status of the print job in the printer queues and printer. This can allow your application to show things like "out of paper" issues, and when the print job actually reaches the printer. However, this is often implemented using polling, and should not be enabled unless needed.	Gtk.PrintOperation
	unit : Gtk.Unit The transformation for the cairo context obtained from GtkPrintContext is set up in such a way that distances are measured in units of unit. The transformation for the cairo context obtained from GtkPrintContext is set up in such a way that distances are measured in units of unit.	Gtk.PrintOperation
	use_full_page : Boolean If TRUE, the transformation for the cairo context obtained from GtkPrintContext puts the origin at the top left corner of the page (which may not be the top left corner of the sheet, depending on page orientation and the number of pages per sheet). If TRUE, the transformation for the cairo context obtained from GtkPrintContext puts the origin at the top left corner of the page (which may not be the top left corner of the sheet, depending on page orientation and the number of pages per sheet). Otherwise, the origin is at the top left corner of the imageable area (i.e. inside the margins).	Gtk.PrintOperation

	is_finished () : Boolean A convenience function to find out if the print operation is finished, either successfully (GTK_PRINT_STATUS_FINISHED) or unsuccessfully (GTK_PRINT_STATUS_FINISHED_ABORTED). A convenience function to find out if the print operation is finished, either successfully (GTK_PRINT_STATUS_FINISHED) or unsuccessfully (GTK_PRINT_STATUS_FINISHED_ABORTED). can be in a non-finished state even after done has been called, as the operation status then tracks the print job status on the printer. Returns: Boolean	Gtk.PrintOperation
	is_selected (Number *page_nr) : Boolean Returns whether the given page is included in the set of pages that have been selected for printing. Returns whether the given page is included in the set of pages that have been selected for printing. Parameters: Number page_nr* Required (not null) Returns: Boolean	Gtk.PrintOperationPreview

Renders a page to the preview, using the print context that was passed to the GtkPrintOperation::preview handler together with preview. A custom iprint preview should use this function in its ::expose handler to render the currently selected page. Note that this function requires a suitable cairo context to be associated with the print context. Parameters: Number page_nr* Required (not null) Returns: none	Gtk.PrintOperationPreview
	run (PrintOperationAction *action, Window parent) : Gtk.PrintOperationResult Runs the print operation, by first letting the user modify print settings in the print dialog, and then print the document. Runs the print operation, by first letting the user modify print settings in the print dialog, and then print the document. Normally that this function does not return until the rendering of all pages is complete. You can connect to the GtkPrintOperation::status-changed signal on op to obtain some information about the progress of the print operation. Furthermore, it may use a recursive mainloop to show the print dialog. If you call gtk_print_operation_set_allow_async() or set the GtkPrintOperation:allow-async property the operation will run asynchronously if this is supported on the platform. The GtkPrintOperation::done signal will be emitted with the result of the operation when the it is done (i.e. when the dialog is canceled, or when the print succeeds or fails). \|[ if (settings != NULL) gtk_print_operation_set_print_settings (print, settings); if (page_setup != NULL) gtk_print_operation_set_default_page_setup (print, page_setup); g_signal_connect (print, "begin-print", G_CALLBACK (begin_print), &data); g_signal_connect (print, "draw-page", G_CALLBACK (draw_page), &data); res = gtk_print_operation_run (print, GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG, parent, &error); if (res == GTK_PRINT_OPERATION_RESULT_ERROR) { error_dialog = gtk_message_dialog_new (GTK_WINDOW (parent), GTK_DIALOG_DESTROY_WITH_PARENT, GTK_MESSAGE_ERROR, GTK_BUTTONS_CLOSE, "Error printing file:\ns", error->message); g_signal_connect (error_dialog, "response", G_CALLBACK (gtk_widget_destroy), NULL); gtk_widget_show (error_dialog); g_error_free (error); } else if (res == GTK_PRINT_OPERATION_RESULT_APPLY) { if (settings != NULL) g_object_unref (settings); settings = g_object_ref (gtk_print_operation_get_print_settings (print)); } ]\| Note that gtk_print_operation_run() can only be called once on a given GtkPrintOperation. GTK_PRINT_OPERATION_RESULT_APPLY* indicates that the printing was completed successfully. In this case, it is a good idea to obtain the used print settings with gtk_print_operation_get_print_settings() and store them for reuse with the next print operation. A value of GTK_PRINT_OPERATION_RESULT_IN_PROGRESS means the operation is running asynchronously, and will emit the GtkPrintOperation::done signal when done. Parameters: Gtk.PrintOperationAction action Required (not null) Gtk.Window parent Transient parent of the dialog Returns: Gtk.PrintOperationResult	Gtk.PrintOperation
	set_allow_async (Boolean *allow_async) : none Sets whether the gtk_print_operation_run() may return before the print operation is completed.

Parameters: Gtk.PageSetup default_page_setup a GtkPageSetup, or NULL Returns: none	Gtk.PrintOperation
	set_defer_drawing () : none Sets up the GtkPrintOperation to wait for calling of gtk_print_operation_draw_page_finish() from application. Sets up the GtkPrintOperation to wait for calling of gtk_print_operation_draw_page_finish() from application. It can be used for drawing page in another thread. This function must be called in the callback of "draw-page" signal. Returns: none	Gtk.PrintOperation
	set_embed_page_setup (Boolean *embed) : none Embed page size combo box and orientation combo box into page setup page. Embed page size combo box and orientation combo box into page setup page.

	set_job_name (String *job_name) : none Sets the name of the print job. Sets the name of the print job. The name is used to identify the job (e.g. in monitoring applications like eggcups). If you don't set a job name, GTK+ picks a default one by numbering successive print jobs. Parameters: String job_name* Required (not null) Returns: none	Gtk.PrintOperation
	set_n_pages (Number *n_pages) : none Sets the number of pages in the document. Sets the number of pages in the document. This must be set to a positive number before the rendering starts. It may be set in a GtkPrintOperation::begin-print signal hander. Note that the page numbers passed to the GtkPrintOperation::request-page-setup and GtkPrintOperation::draw-page signals are 0-based, i.e. if the user chooses to print all pages, the last ::draw-page signal will be for page n_pages* - 1. Parameters: Number n_pages Required (not null) Returns: none	Gtk.PrintOperation

	set_track_print_status (Boolean *track_status) : none If track_status is TRUE, the print operation will try to continue report on the status of the print job in the printer queues and printer. If track_status is TRUE, the print operation will try to continue report on the status of the print job in the printer queues and printer. This can allow your application to show things like "out of paper" issues, and when the print job actually reaches the printer. This function is often implemented using some form of polling, so it should not be enabled unless needed. Parameters: Boolean track_status* Required (not null) Returns: none	Gtk.PrintOperation

Events - usage syntax: this.signals.EVENTNAME.connect( Function )
Event		Defined By
	begin_print (PrintOperation *self, PrintContext context) : none Emitted after the user has finished changing print settings in the dialog, before the actual rendering starts. Emitted after the user has finished changing print settings in the dialog, before the actual rendering starts. A typical use for ::begin-print is to use the parameters from the GtkPrintContext* and paginate the document accordingly, and then set the number of pages with gtk_print_operation_set_n_pages(). Parameters: Gtk.PrintOperation self Gtk.PrintContext context Returns: {none}	Gtk.PrintOperation
	create_custom_widget (PrintOperation *self) : GObject.Object Emitted when displaying the print dialog. Emitted when displaying the print dialog. If you return a widget in a handler for this signal it will be added to a custom tab in the print dialog. You typically return a container widget with multiple widgets in it. The print dialog owns the returned widget, and its lifetime is not controlled by the application. However, the widget is guaranteed to stay around until the GtkPrintOperation::custom-widget-apply signal is emitted on the operation. Then you can read out any information you need from the widgets. or NULL* Parameters: Gtk.PrintOperation self Returns: {GObject.Object}	Gtk.PrintOperation
	custom_widget_apply (PrintOperation *self, Widget widget) : none Emitted right before GtkPrintOperation::begin-print if you added a custom widget in the GtkPrintOperation::create-custom-widget handler. Emitted right before GtkPrintOperation::begin-print if you added a custom widget in the GtkPrintOperation::create-custom-widget handler. When you get this signal you should read the information from the custom widgets, as the widgets are not guaraneed to be around at a later time. Parameters: Gtk.PrintOperation self* Gtk.Widget widget Returns: {none}	Gtk.PrintOperation
	done (PrintOperation *self, PrintOperationResult result) : none Emitted when the print operation run has finished doing everything required for printing. Emitted when the print operation run has finished doing everything required for printing. If result* is GTK_PRINT_OPERATION_RESULT_ERROR then you can call gtk_print_operation_get_error() for more information. If you enabled print status tracking then gtk_print_operation_is_finished() may still return FALSE after GtkPrintOperation::done was emitted. Parameters: Gtk.PrintOperation self Gtk.PrintOperationResult result Returns: {none}	Gtk.PrintOperation
	draw_page (PrintOperation *self, PrintContext context, Number page_nr) : none Emitted for every page that is printed. Emitted for every page that is printed. The signal handler must render the page_nr's page onto the cairo context obtained from context* using gtk_print_context_get_cairo_context(). \|[ static void draw_page (GtkPrintOperation operation, GtkPrintContext context, gint page_nr, gpointer user_data) { cairo_t cr; PangoLayout layout; gdouble width, text_height; gint layout_height; PangoFontDescription desc; cr = gtk_print_context_get_cairo_context (context); width = gtk_print_context_get_width (context); cairo_rectangle (cr, 0, 0, width, HEADER_HEIGHT); cairo_set_source_rgb (cr, 0.8, 0.8, 0.8); cairo_fill (cr); layout = gtk_print_context_create_pango_layout (context); desc = pango_font_description_from_string ("sans 14"); pango_layout_set_font_description (layout, desc); pango_font_description_free (desc); pango_layout_set_text (layout, "some text", -1); pango_layout_set_width (layout, width PANGO_SCALE); pango_layout_set_alignment (layout, PANGO_ALIGN_CENTER); pango_layout_get_size (layout, NULL, &layout_height); text_height = (gdouble)layout_height / PANGO_SCALE; cairo_move_to (cr, width / 2, (HEADER_HEIGHT - text_height) / 2); pango_cairo_show_layout (cr, layout); g_object_unref (layout); } ]\| Use gtk_print_operation_set_use_full_page() and gtk_print_operation_set_unit() before starting the print operation to set up the transformation of the cairo context according to your needs. Parameters: Gtk.PrintOperation self Gtk.PrintContext context Number page_nr Returns: {none}	Gtk.PrintOperation
	end_print (PrintOperation *self, PrintContext context) : none Emitted after all pages have been rendered. Emitted after all pages have been rendered. A handler for this signal can clean up any resources that have been allocated in the GtkPrintOperation::begin-print handler. Parameters: Gtk.PrintOperation self* Gtk.PrintContext context Returns: {none}	Gtk.PrintOperation
	got_page_size (PrintOperationPreview *self, PrintContext context, PageSetup page_setup) : none The ::got-page-size signal is emitted once for each page that gets rendered to the preview. The ::got-page-size signal is emitted once for each page that gets rendered to the preview. A handler for this signal should update the context* according to page_setup and set up a suitable cairo context, using gtk_print_context_set_cairo_context(). Parameters: Gtk.PrintOperationPreview self Gtk.PrintContext context Gtk.PageSetup page_setup Returns: {none}	Gtk.PrintOperationPreview
	paginate (PrintOperation *self, PrintContext context) : Boolean Emitted after the GtkPrintOperation::begin-print signal, but before the actual rendering starts. Emitted after the GtkPrintOperation::begin-print signal, but before the actual rendering starts. It keeps getting emitted until a connected signal handler returns TRUE. The ::paginate signal is intended to be used for paginating a document in small chunks, to avoid blocking the user interface for a long time. The signal handler should update the number of pages using gtk_print_operation_set_n_pages(), and return TRUE* if the document has been completely paginated. If you don't need to do pagination in chunks, you can simply do it all in the ::begin-print handler, and set the number of pages from there. Parameters: Gtk.PrintOperation self Gtk.PrintContext context Returns: {Boolean}	Gtk.PrintOperation
	preview (PrintOperation *self, PrintOperationPreview preview, PrintContext context, Window parent) : Boolean Gets emitted when a preview is requested from the native dialog. Gets emitted when a preview is requested from the native dialog. The default handler for this signal uses an external viewer application to preview. To implement a custom print preview, an application must return TRUE* from its handler for this signal. In order to use the provided context for the preview implementation, it must be given a suitable cairo context with gtk_print_context_set_cairo_context(). The custom preview implementation can use gtk_print_operation_preview_is_selected() and gtk_print_operation_preview_render_page() to find pages which are selected for print and render them. The preview must be finished by calling gtk_print_operation_preview_end_preview() (typically in response to the user clicking a close button). Parameters: Gtk.PrintOperation self Gtk.PrintOperationPreview preview Gtk.PrintContext context Gtk.Window parent Returns: {Boolean}	Gtk.PrintOperation
	ready (PrintOperationPreview *self, PrintContext context) : none The ::ready signal gets emitted once per preview operation, before the first page is rendered. The ::ready signal gets emitted once per preview operation, before the first page is rendered. A handler for this signal can be used for setup tasks. Parameters: Gtk.PrintOperationPreview self* Gtk.PrintContext context Returns: {none}	Gtk.PrintOperationPreview
	request_page_setup (PrintOperation *self, PrintContext context, Number page_nr, PageSetup setup) : none Emitted once for every page that is printed, to give the application a chance to modify the page setup. Emitted once for every page that is printed, to give the application a chance to modify the page setup. Any changes done to setup* will be in force only for printing this page. Parameters: Gtk.PrintOperation self Gtk.PrintContext context Number page_nr Gtk.PageSetup setup Returns: {none}	Gtk.PrintOperation
	status_changed (PrintOperation *self) : none Emitted at between the various phases of the print operation. Emitted at between the various phases of the print operation. See GtkPrintStatus* for the phases that are being discriminated. Use gtk_print_operation_get_status() to find out the current status. Parameters: Gtk.PrintOperation self Returns: {none}	Gtk.PrintOperation
	update_custom_widget (PrintOperation *self, Widget widget, PageSetup setup, PrintSettings settings) : none Emitted after change of selected printer. Emitted after change of selected printer. The actual page setup and print settings are passed to the custom widget, which can actualize itself according to this change.
