Re: [Gtk-osx-users] Random crashes when printing on OS X



I am now also getting this when I print, after having added a cairo_clip() to bound my drawings into a (0,0),(1,1) region. But I do not get it when I am displaying to screen, only printing, and I use the same function for both, one simply gets the cairo_t from the drawing area, the other retrieves it from the printer.

Any ideas?

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.
