[Interest] Memory leak

[Igor Mironchik]

And to avoid memory leak just give to the Widget the parent. And when 
parent will die he will delete your Widget. It's just as example...

But to answer to your question more clearly we need to know some more 
details. Such as what widget is doing, when he should die, and so on...
