Subject: Random crashes when printing on OS X
Date: Thu, 4 Feb 2010 18:44:10 -0500
I am using the GtkPrint* functions to print. However at what seems to be random
occurrences the application crashes with the following error:
Gdk:ERROR:gdkeventloop-quartz.c:559:select_thread_collect_poll: assertion
failed: (ufds[i].fd == current_pollfds[i].fd)
Abort trap
When the user clicks on the print button a signal is generated and the
application comand function executes based on the following case statement:
...
case ISI_PERM_MENU_COMPONENT_FORMULA_PRINT:
if( isi_app_check_permission(prev_self,
ISI_PERM_MENU_COMPONENT_FORMULA_PRINT) && prev_self->component != NULL){
isi_display_page_setup( prev_self->display,
prev_self->component,FALSE);
isi_display_print(prev_self->display);
} else {
isi_user_message(NULL,"Not Allowed","You do not have
permission to print formulas.",0);
}
break;
...
void isi_display_print(IsiDisplay *self){
GtkPrintOperation *print = NULL;
GtkPrintSettings *printer_settings = NULL;
GtkPageSetup *page_setup = NULL;
GtkPaperSize *paper_size = NULL;
guint ctype;
/* Sanity Check */
g_return_if_fail(self != NULL);
g_return_if_fail(ISI_IS_DISPLAY(self) != FALSE);
g_return_if_fail(self->priv != NULL);
g_return_if_fail(self->priv->dispose_has_run != TRUE);
/* Create a new print operation */
print = gtk_print_operation_new();
/* Create new page setup and paper size */
page_setup = gtk_page_setup_new();
paper_size = gtk_paper_size_new(GTK_PAPER_NAME_LETTER);
gtk_page_setup_set_paper_size(page_setup,paper_size);
/* Set the default to the new page setup */
gtk_print_operation_set_default_page_setup(print,page_setup);
/* Make sure we always do full page printing*/
gtk_print_operation_set_unit(print,GTK_UNIT_INCH);
gtk_print_operation_set_use_full_page(print,TRUE);
gtk_print_operation_set_n_pages (print, self->priv->page_count);
g_signal_connect(print, "draw-page",
G_CALLBACK(isi_display_print_event),(gpointer)self);
/* SOMEWHERE IN THIS FUNCTION THE DIALOG BLOWS UP!! */
gtk_print_operation_run(print,GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG,NULL,NULL);
return;}
Any help would be greatly appreciated.
The problem is pervasive will most printer types, but is exacerbated with the
HP CP3525 Color Laserjet printer.
