Qt widget setParent

[jpn]

It seems to prevent the widget from deletion, even when I'm calling delete widget, I'm not sure why.

What does this mean, actually? What do you mean with "prevent something from deletion"?

You're not the first to tell me so.

Indeed, seems you've been warned before in this thread by a bunch of people. Why do you insist doing it wrong? Have you seen any Qt examples allocating widgets or layouts on the stack (excluding main() and modal dialogs)? Or did you ever actually read any of them? Sorry for the tone, but I just don't understand people who regardless of continuous warnings insist of doing things their own (wrong) way.

My problem is memory.

What exact steps did you take to verify this?
