By keeping track of it (either when you create and destroy the widgets or using weak references/weak pointers/destroy callbacks/...). ‘Checking the existence of a widget’ is, essentially, a meaningless phrase. If the widget has been destroyed you do not have any means to *refer* to it. You cannot ask ‘does this widget exist’ because there is no way to say ‘this widget’. Using the pointer to the memory the widget used to occupy for anything is a programming error.
