gboolean paginate ( GtkPrintOperation* self, GtkPrintContext* context, gpointer user_data )
Emitted after the ::begin-print signal, but before the actual rendering starts.
It keeps getting emitted until a connected signal handler returns
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.
|Default handler: |
The default handler is called after the handlers added via
GtkPrintContextfor the current operation.
The data is owned by the caller of the function.
