virtual void Gtk::PrintOperationPreview::on_ready | ( | const Glib::RefPtr< PrintContext >& | context | ) | [protected, virtual] |
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.
page_nr | The page to render. |

Glib::SignalProxy2< void,const Glib::RefPtr<PrintContext>&,const Glib::RefPtr<PageSetup>& > Gtk::PrintOperationPreview::signal_got_page_size | ( | ) |
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_print_context_set_cairo_context().
context | The current Gtk::PrintContext. |
page_setup | The Gtk::PageSetup for the current page. |
Glib::SignalProxy1< void,const Glib::RefPtr<PrintContext>& > Gtk::PrintOperationPreview::signal_ready | ( | ) |
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.
context | The current Gtk::PrintContext. |
Glib::RefPtr< Gtk::PrintOperationPreview > wrap | ( | GtkPrintOperationPreview * | object, |

) | [related] |
A Glib::wrap() method for this object.
object | The C instance. |
take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
