Detailed Description

PrintOperation is the high-level, portable printing API.

It looks a bit different than other GTK+ dialogs such as the FileChooser, since some platforms don't expose enough infrastructure to implement a good print dialog. On such platforms, PrintOperation uses the native print dialog. On platforms which do not provide a native print dialog, GTK+ uses its own, see PrintUnixDialog.

The typical way to use the high-level printing API is to create a PrintOperation object when the user chooses to print. Then you set some properties on it,such as the page size, any PrintSettings from previous print operations, the number of pages, the current page, etc.

Then you start the print operation by calling run(). It will then show a dialog to let the user select a printer and options. When the user finishes the dialog various signals will be emitted by the PrintOperation for you to handle, the main one being draw_page. You should then render the page on the provided PrintContext using Cairo.

Since gtkmm 2.10:

Member Function Documentation

◆ cancel()

void Gtk::PrintOperation::cancel ( )

Cancels a running print operation.

This function may be called from a signal_begin_print(), signal_paginate() or signal_draw_page() signal handler to stop the currently running print operation.

◆ create()

static Glib::RefPtr<PrintOperation> Gtk::PrintOperation::create ( )
static

◆ draw_page_finish()

void Gtk::PrintOperation::draw_page_finish ( )

Signal that drawing of particular page is complete.

It is called after completion of page drawing (e.g. drawing in another thread). If set_defer_drawing() was called before, then this function has to be called by application. Otherwise it is called by GTK itself.

◆ get_default_page_setup() [1/2]

Glib::RefPtr<PageSetup> Gtk::PrintOperation::get_default_page_setup ( )

Returns the default page setup.

Returns
The default page setup.

◆ get_default_page_setup() [2/2]

Glib::RefPtr<const PageSetup> Gtk::PrintOperation::get_default_page_setup ( ) const

Returns the default page setup.

Returns
The default page setup.

◆ get_embed_page_setup()

bool Gtk::PrintOperation::get_embed_page_setup ( ) const

Gets whether page setup selection combos are embedded.

Returns
Whether page setup selection combos are embedded.

◆ get_has_selection()

bool Gtk::PrintOperation::get_has_selection ( ) const

Gets whether there is a selection.

Returns
Whether there is a selection.

◆ get_n_pages_to_print()

int Gtk::PrintOperation::get_n_pages_to_print ( ) const

Returns the number of pages that will be printed.

Note that this value is set during print preparation phase (Gtk::PrintStatus::PREPARING), so this function should never be called before the data generation phase (Gtk::PrintStatus::GENERATING_DATA). You can connect to the signal_status_changed() signal and call get_n_pages_to_print() when print status is Gtk::PrintStatus::GENERATING_DATA.

This is typically used to track the progress of print operation.

Returns
The number of pages that will be printed.

◆ get_print_settings() [1/2]

Glib::RefPtr<PrintSettings> Gtk::PrintOperation::get_print_settings ( )

Returns the current print settings.

Note that the return value is nullptr until either set_print_settings() or run() have been called.

Returns
The current print settings of op.

◆ get_print_settings() [2/2]

Glib::RefPtr<const PrintSettings> Gtk::PrintOperation::get_print_settings ( ) const

Returns the current print settings.

Note that the return value is nullptr until either set_print_settings() or run() have been called.

Returns
The current print settings of op.

◆ get_status()

PrintStatus Gtk::PrintOperation::get_status ( ) const

Returns the status of the print operation.

Also see get_status_string().

Returns
The status of the print operation.

◆ get_status_string()

Glib::ustring Gtk::PrintOperation::get_status_string ( ) const

Returns 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 Gtk::Statusbar.

Use get_status() to obtain a status value that is suitable for programmatic use.

Returns
A string representation of the status of the print operation.

◆ get_support_selection()

bool Gtk::PrintOperation::get_support_selection ( ) const

Gets whether the application supports print of selection.

Returns
Whether the application supports print of selection.

◆ get_type()

static GType Gtk::PrintOperation::get_type ( )
static

Get the GType for this class, for use with the underlying GObject type system.

◆ gobj() [1/2]

GtkPrintOperation* Gtk::PrintOperation::gobj ( )
inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GtkPrintOperation* Gtk::PrintOperation::gobj ( ) const
inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GtkPrintOperation* Gtk::PrintOperation::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

◆ is_finished()

bool Gtk::PrintOperation::is_finished ( ) const

A convenience function to find out if the print operation is finished.

a print operation is finished if its status is either Gtk::PrintStatus::FINISHED or Gtk::PrintStatus::FINISHED_ABORTED.

Note
when you enable print status tracking the print operation 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
true, if the print operation is finished.

◆ run() [1/2]

Result Gtk::PrintOperation::run ( Action  action,
Window parent 
)

Runs the print operation.

Normally that this function does not return until the rendering of all pages is complete. You can connect to the signal_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 set the [Gtk.PrintOperation:allow-async] property, the operation will run asynchronously if this is supported on the platform. The signal_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).

[C example ellipted]

Note that run() can only be called once on a given Gtk::PrintOperation.

Parameters
actionThe action to start.
parentTransient parent of the dialog.
Returns
The result of the print operation. A return value of Gtk::PrintOperation::Result::APPLY indicates that the printing was completed successfully. In this case, it is a good idea to obtain the used print settings with get_print_settings() and store them for reuse with the next print operation. A value of Gtk::PrintOperation::Result::IN_PROGRESS means the operation is running asynchronously, and will emit the signal_done() signal when done.
Exceptions
Glib::Error

Flags: Run Last

Emitted after the user has finished changing print settings in the dialog, before the actual rendering starts.

A typical use for signal_begin_print() is to use the parameters from the Gtk::PrintContext and paginate the document accordingly, and then set the number of pages with Gtk::PrintOperation::set_n_pages().

Parameters
contextThe Gtk::PrintContext for the current operation.

◆ signal_create_custom_widget()

Glib::SignalProxy<Widget*()> Gtk::PrintOperation::signal_create_custom_widget ( )
Slot Prototype:
Widget* on_my_create_custom_widget()

Flags: Run Last

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 signal_custom_widget_apply() signal is emitted on the operation. Then you can read out any information you need from the widgets.

Returns
A custom widget that gets embedded in the print dialog.

◆ signal_custom_widget_apply()

Glib::SignalProxy<void(Widget*)> Gtk::PrintOperation::signal_custom_widget_apply ( )
Slot Prototype:
void on_my_custom_widget_apply(Widget* widget)

Flags: Run Last

Emitted right before signal_begin_print() if you added a custom widget in the signal_create_custom_widget() handler.

When you get this signal you should read the information from the custom widgets, as the widgets are not guaranteed to be around at a later time.

Parameters
widgetThe custom widget added in signal_create_custom_widget().

◆ signal_done()

Glib::SignalProxy<void(Result)> Gtk::PrintOperation::signal_done ( )
Slot Prototype:
void on_my_done(Result result)

Flags: Run Last

Emitted when the print operation run has finished doing everything required for printing.

result gives you information about what happened during the run. If result is Gtk::PrintOperation::Result::ERROR then you can call Gtk::PrintOperation::get_error() for more information.

If you enabled print status tracking then Gtk::PrintOperation::is_finished() may still return false after the signal_done() signal was emitted.

Parameters
resultThe result of the print operation.

◆ signal_draw_page()

Glib::SignalProxy<void(const Glib::RefPtr<PrintContext>&, int)> Gtk::PrintOperation::signal_draw_page ( )
Slot Prototype:
void on_my_draw_page(const Glib::RefPtr<PrintContext>& context, int page_nr)

Flags: Run Last

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::PrintContext::get_cairo_context().

[C example ellipted]

Use Gtk::PrintOperation::set_use_full_page() and Gtk::PrintOperation::set_unit() before starting the print operation to set up the transformation of the cairo context according to your needs.

Parameters
contextThe Gtk::PrintContext for the current operation.
page_nrThe number of the currently printed page (0-based).

◆ signal_end_print()

Glib::SignalProxy<void(const Glib::RefPtr<PrintContext>&)> Gtk::PrintOperation::signal_end_print ( )
Slot Prototype:
void on_my_end_print(const Glib::RefPtr<PrintContext>& context)

Flags: Run Last

Emitted after all pages have been rendered.

A handler for this signal can clean up any resources that have been allocated in the signal_begin_print() handler.

Parameters
contextThe Gtk::PrintContext for the current operation.

◆ signal_paginate()

Glib::SignalProxy<bool(const Glib::RefPtr<PrintContext>&)> Gtk::PrintOperation::signal_paginate ( )
Slot Prototype:
bool on_my_paginate(const Glib::RefPtr<PrintContext>& context)

Flags: Run Last

Emitted after the signal_begin_print() signal, but before the actual rendering starts.

It keeps getting emitted until a connected signal handler returns true.

The signal_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::PrintOperation::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 signal_begin_print() handler, and set the number of pages from there.

Parameters
contextThe Gtk::PrintContext for the current operation.
Returns
true if pagination is complete.

◆ signal_preview()

Glib::SignalProxy<bool(const Glib::RefPtr<PrintOperationPreview>&, const Glib::RefPtr<PrintContext>&, Window*)> Gtk::PrintOperation::signal_preview ( )
Slot Prototype:
bool on_my_preview(const Glib::RefPtr<PrintOperationPreview>& preview, const Glib::RefPtr<PrintContext>& context, Window* parent)

Flags: Run Last

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::PrintContext::set_cairo_context().

The custom preview implementation can use Gtk::PrintOperationPreview::is_selected() and Gtk::PrintOperationPreview::render_page() to find pages which are selected for print and render them. The preview must be finished by calling Gtk::PrintOperationPreview::end_preview() (typically in response to the user clicking a close button).

Parameters
previewThe Gtk::PrintOperationPreview for the current operation.
contextThe Gtk::PrintContext that will be used.
parentThe Gtk::Window to use as window parent.
Returns
true if the listener wants to take over control of the preview.

void on_my_request_page_setup(const Glib::RefPtr<PrintContext>& context, int page_no, const Glib::RefPtr<PageSetup>& setup)

Flags: Run Last

Emitted once for every page that is printed.

This gives the application a chance to modify the page setup. Any changes done to setup will be in force only for printing this page.

Parameters
contextThe Gtk::PrintContext for the current operation.
page_noThe number of the currently printed page (0-based).
setupThe Gtk::PageSetup.

◆ signal_status_changed()

Glib::SignalProxy<void()> Gtk::PrintOperation::signal_status_changed ( )
Slot Prototype:
void on_my_status_changed()
