ok, so that means when i have a model dialog on STACK with another widget as parent..thats not wrong? one would think it should be...when parent will try to delete it, it should be crashing time..or am i getting smth really wrong about model dialog??.or maybe u can create a model dialog on stack and not give it a parent..in these examples, 'this' is parent, so be a dialog model or not, dialog creation on stack should be wrong.
