PrintOperation.setNPages
void setNPages(int nPages)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 gtk.print_operation.PrintOperation.beginPrint signal handler.
Note that the page numbers passed to the gtk.print_operation.PrintOperation.requestPageSetup and gtk.print_operation.PrintOperation.drawPage 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.
Parameters
nPages | the number of pages |
