What happened when Qt Widget SetParent(NULL)
here is my code:
QPushButton* button = new QPushButton;
button.setParent(&window); // button appear on window
button.setParent(NULL); // button disappear on window
button.setParent(&window); // button appear on window again
when I setParent(&window) again, I realize that the button were not release by setParent(NULL).
My question is, if I not setParent(&window) again, when button release himself, now it leave from his parentï¼

Setting a null parent makes a widget a top-level window.
