Hello, I am getting mysterious and inconsistent crashes in my gtk program (ie it isn't crashing in the same spot every time), and I believe it has something to do with how I am destroying a set of widgets. I have an hbox (HB) packed into a vbox (VB). HB has many widgets packed inside of it, most of which are also created/maintained in their own C++ classes. One of the widgets is a GnomeCanvas, and it itself has many GnomeCanvasItem children, nearly each maintained in seperate C++ classes as well. At times, I need to entirely remove HB and all of it's children including the canvas and all of it's children. I then recreate everything from scratch and pack into VB. Actually the destroy seems to work OK. It is when I try to recreate all the widgets that I get the core dump. I tried having each class destructor first delete it's children (with a 'delete'), then destroy it's own widget (in the case of the GnomeCanvasItems, using GTK_OBJECT_DESTROY and casting the CanvasItem). I thought this made the most sense since you want to delete the children first before you delete the parent or you'll have children pointing to parents that no longer exist. I also tried reversing the order as well but get the same result. I get error messages like this: GLib-GObject-WARNING **: invalid uninstantiatable type `gint64' in cast to `GtkObject' Gtk-CRITICAL **: file gtkobject.c: line 358 (gtk_object_destroy): assertion `GTK_IS_OBJECT (object)' failed GLib-GObject-WARNING **: invalid cast from `(null)' to `GtkObject' Gtk-CRITICAL **: file gtkobject.c: line 358 (gtk_object_destroy): assertion `GTK_IS_OBJECT (object)' failed I tried just doing a destroy on HB but get the same results. It seems like I'm leaving something behind. It works a few times, then crashes. Or it crashes on the first try. Thanks for any help Jason _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
