Re: Using GtkFileChooserWidget

[Nikolaj Thygesen <nikolaj thygesen diamondbox dk>]

Hi,

   I'll just reply to my own post with an example on how to reproduce 
the error-dump. This is no pretty program which simply either inserts or 
removes the same widget every other time the window close widget is 
clicked - just to keep it brief. Who might I contact regarding this issue??

GtkWidget *window;
GtkWidget *file_widget;
gboolean delete_event(GtkWidget *widget, GdkEvent *event, WindowThread 
*_this)
{
   if(GtkWidget *sub = gtk_bin_get_child(GTK_BIN(window)))
       gtk_container_remove(GTK_CONTAINER(window), sub);
   else
       gtk_container_add(GTK_CONTAINER(window), file_widget);
   return TRUE;
}


int main()
{
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
file_widget = gtk_file_chooser_widget_new(GTK_FILE_CHOOSER_ACTION_SAVE);
g_object_ref(file_widget);
g_signal_connect(G_OBJECT(window), "delete_event", 
G_CALLBACK(delete_event), 0);
gtk_container_add(GTK_CONTAINER(window), file_widget);
gtk_widget_show_all(window);
gtk_main();
return 0;
}

   br - N :o)
