Signal
Gtk.PrintOperation::paginate
Declaration
gboolean
paginate (
GtkPrintOperation self,
GtkPrintContext* context,
gpointer user_data
)
Description [src]
Emitted after the ::begin-print signal, but before the actual rendering starts.
It keeps getting emitted until a connected signal handler returns TRUE
.
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.
