set_n_pages

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 [signal@Gtk.PrintOperation: GtkPrintOperation:begin-print] signal handler.

Note that the page numbers passed to the [signal@Gtk.PrintOperation:GtkPrintOperation:request-page-setup] and [ signal@Gtk.PrintOperation: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.
