Signal

GtkPrintOperation::paginate

since: 2.10

Declaration

gboolean
paginate (
  GtkPrintOperation* self,
  GtkPrintContext* context,
  gpointer user_data
)

Description [src]

Emitted after the GtkPrintOperation::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.

Default handler:

The default handler is called after the handlers added via g_signal_connect().

Available since: 2.10

Parameters

context

Type: GtkPrintContext

The GtkPrintContext for the current operation.

The data is owned by the caller of the function.

Return value

Type: gboolean

TRUE if pagination is complete.
