How to keep QWidget always on top?

Question

I have two buttons on my QMainWindow. One for btnShowKb and another btnHideKb. When I click btnShowKb, it shows a QWidget. I want this QWidget to always be on top of all windows until I click btnHideKb. When it's on top, I want to activate QWidget and QMainWidget.

Can anyone suggest this?

Answer 1

Setting setWindowFlags () with Qt :: WindowStaysOnTopHint is intended to help.

mainMenu->setWindowFlags(Qt::WindowStaysOnTopHint);
