How keep a QWidget always on top?

Question

I have two buttons on my QMainWindow. One to btnShowKb and another btnHideKb. When i press btnShowKb it shows an QWidget. I want this QWidget always to be on top of all windows till I press btnHideKb. When its on top, I want both QWidget and QMainWidget be activated.

Can anybody suggest on this?

New link: http://doc.qt.io/qt-5/qtwidgets-widgets-windowflags-example.html

and the line of code you might be looking for:

mainMenu->setWindowFlags(Qt::WindowStaysOnTopHint);

Answer 2

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