If you want motion notify events you will have to tell the widget about this wish. gtk_widget_add_events() should solve your problem. > *delete_event* > Since I am using events emitted from the hbox, I g_malloc() an > array of the 16 toggle buttons and pass it as a parameter in the > above-mentioned callbacks.

All widgets are destroyed at one point so you should connect to the "destroy" _signal_. > (*code snippet below*) I am sorry but that code is close to unreadable.
