I'm trying implementing dynamic object creation for a language binding. First of all, I need to be able to simply create objects without specifying attributes, and free them. This seems this works for some types (GtkAction) but not for others (GtkWindow). int main (int argc, char *argv[]){ gtk_init (&argc, &argv); gpointer x = g_object_newv(GTK_TYPE_ACTION, 0, NULL); g_object_unref(x); gpointer y = g_object_newv(GTK_TYPE_WINDOW, 0, NULL); g_object_unref(y); /*** GLib-GObject-WARNING **: invalid unclassed pointer in cast to GtkObject GLib-GObject-WARNING **: instance with invalid (NULL) class pointer GLib-GObject-CRITICAL **: file gsignal.c: line 1767: assertion `G_TYPE_CHECK_INSTANCE (instance)' failed Access violation reading location 0xaaaaaaac ***/ ... } Same happens with gtk_widget_new and gtk_window_new Is it not possible to create a GtkWindow object and trash it right away, or am I doing it the wrong way? _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
