gtkPrintOperationGetNPagesToPrint {RGtk2} | R Documentation |
Returns the number of pages that will be printed.
gtkPrintOperationGetNPagesToPrint(object)
|
Note that this value is set during print preparation phase
(GTK_PRINT_STATUS_PREPARING
), so this function should never be
called before the data generation phase (GTK_PRINT_STATUS_GENERATING_DATA
).
You can connect to the
"status-changed"signal and call
gtkPrintOperationGetNPagesToPrint
when
print status is GTK_PRINT_STATUS_GENERATING_DATA
.
This is typically used to track the progress of print operation.
Since 2.18
