How to close all windows that were created in main()?

EDIT: Btw, make sure you allocate widgets on stack if you set Qt::WA_DeleteOnClose attribute! Otherwise you'll get a crash due to double delete...

On the stack? I thought this allocates an object on the heap:

Object *example = new Object;

Object *example = new Object;

To copy to clipboard, switch view to plain text mode 

Anyways it works like you suggested, thank you!

Argh, sorry. I was in a hurry when answering. I meant heap while I still wrote stack..
