HI,
I have a widget which is "freed Handle" .
It is not null. Is there a way to check if
the widget is valid or a freed handle.
Let me know.
Thanks,
kgs

Freed Handle
No, there is no way. A widget is a pointer, and the pointer could be pointing to memory which has been freed and reused and looks good.
To track widget destruction, use XtNdestroyCallback.
