void Gtk::PrintOperationPreview::end_preview ( )

Ends a preview.

This function must be called to finish a custom print preview.

Since gtkmm 2.10:
virtual void Gtk::PrintOperationPreview::end_preview_vfunc ( )
virtual
GtkPrintOperationPreview* Gtk::PrintOperationPreview::gobj ( )
inline

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gtk::PrintOperation.

const GtkPrintOperationPreview* Gtk::PrintOperationPreview::gobj ( ) const
inline

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gtk::PrintOperation.

bool Gtk::PrintOperationPreview::is_selected ( int  page_nr) const

Returns whether the given page is included in the set of pages that have been selected for printing.

Since gtkmm 2.10:
Parameters:
page_nrA page number.
Returns:
true if the page has been selected for printing.
virtual bool Gtk::PrintOperationPreview::is_selected_vfunc ( int  page_nr) const
virtual
virtual void Gtk::PrintOperationPreview::on_got_page_size ( const Glib::RefPtr< PrintContext >&  context,
const Glib::RefPtr< PageSetup >&  page_setup 
)
protectedvirtual

This is a default handler for the signal signal_got_page_size().

virtual void Gtk::PrintOperationPreview::on_ready ( const Glib::RefPtr< PrintContext >&  context)
protectedvirtual

This is a default handler for the signal signal_ready().

void Gtk::PrintOperationPreview::render_page ( int  page_nr)

Renders a page to the preview, using the print context that was passed to the Gtk::PrintOperation::signal_preview() handler together with preview.

A custom iprint preview should use this function in its signal_expose() handler to render the currently selected page.

Note that this function requires a suitable cairo context to be associated with the print context.

Since gtkmm 2.10:
Parameters:
page_nrThe page to render.
virtual void Gtk::PrintOperationPreview::render_page_vfunc ( int  page_nr)
virtual
Glib::SignalProxy2< void,const Glib::RefPtr<PrintContext>&,const Glib::RefPtr<PageSetup>& > Gtk::PrintOperationPreview::signal_got_page_size ( )
Slot Prototype:
void on_my_got_page_size(const Glib::RefPtr<PrintContext>& context, const Glib::RefPtr<PageSetup>& page_setup)

The signal_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::PrintContext::set_cairo_context().

Parameters:
contextThe current Gtk::PrintContext.
page_setupThe Gtk::PageSetup for the current page.
Glib::SignalProxy1< void,const Glib::RefPtr<PrintContext>& > Gtk::PrintOperationPreview::signal_ready ( )
Slot Prototype:
void on_my_ready(const Glib::RefPtr<PrintContext>& context)

The signal_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:
contextThe current Gtk::PrintContext.
