2008-12-19 Marek Kasik <mkasik@redhat.com> Bug 339318 - Allow page rendering to (optionally) happen in a thread * gtk/gtk.symbols: API change * doc/reference/gtk/gtk-sections.txt: API change * gtk/gtkprintoperation-private.h * gtk/gtkprintoperation.h * gtk/gtkprintoperation.c: Adds 2 new functions gtk_print_operation_set_defer_drawing() - Sets up the GtkPrintOperation to wait for calling of gtk_print_operation_draw_page_finish() from application. It can be used for drawing page in another thread. This function must be called in the callback of "draw-page" signal. gtk_print_operation_draw_page_finish() - Signalize that drawing of particular page is complete. It is called after completion of page drawing (e.g. drawing in another thread). If gtk_print_operation_set_defer_drawing() was called before, then this function has to be called by application. In another case it is called by the library itself. svn path=/trunk/; revision=21913
