how to kill parent widget?

[mahe2310]

My application calls another widget from the current and i never need the previous widget.
So i want to kill the parent widget to avoid memory leak.

I want to solve this problem as my widgets chains a lot.

Can anybody help?

delete pWidget;

[mahe2310]

delete pWidget;



If i am reusing it again. then ? :(

pWidget name should be a global variable.. Right???
that means all the widgets should be global...

But if we are declaring these widget together in a header file and calls the header file by each of the file,
then redeclaration error is generated.

If i declare them static in the headers then once we delete it will not be created again.

Try setting Qt::WA_DeleteOnClose attribute or invoking QObject::deleteLater(), but make sure that "parent" widget is not a parent of other windows, because it will delete them also. Another alternative is to turn your windows into singletons and just hide them when you don't need them.
