2006-04-24 Matthias Clasen <mclasen@redhat.com> * gtk/gtk.symbols: * gtk/gtkprintoperation.c (gtk_print_operation_run_async): Refactor the gtk_print_operation_run() code and add an _async version. * gtk/gtkprintoperation-private.h: * gtk/gtkprintoperation-unix.c (_gtk_print_operation_platform_backend_run_dialog_async) (gtk_print_run_page_setup_dialog_async): Variants of the run functions which don't call gtk_dialog_run(), but only show the dialog and return, and handle the response in a signal handler. * gtk/gtkprintoperation-win32.c (gtk_print_run_page_setup_dialog_async) (_gtk_print_operation_platform_backend_run_dialog_async): Implement these by calling the sync versions.
