How to get QHBoxLayout or QVBoxLayout to auto expanding with its parent QWidget in .ui file

lygstate

I didn't found any way to do that.

lygstate

Comes with a result, the QVBoxLayout 's parent should be the TopWidget,
then when we resize the widget, the QVBoxLayout will auto-resize with it's parent widget, that's nice.
