If a widget consumes
a resource that needs explicit freeing, the widget documentation had
better document this so that the application can be sure to destroy the
widget before exiting.
This seems like bad design. I may have a Text widget today that doesn't do
checkpoint files, so my documentation doesn't say it has to be destroyed, and
the application believes this and blithely calls exit. Tomorrow I add
checkpoint files, thinking this to be a nice addition from the user perspective,
and suddenly I have to ask all developers to rewrite their applications? That
doesn't sound like a very good design.
