How to do a fullscreen without borders using QMainWindow ? I got a fullscreen including window borders all around the screen. I would like to have a "real" fullscreen like video games. Not a windowed fullscreen.
I tried:
MainWindow mainWindow;
mainWindow.setWindowState(Qt::WindowFullScreen);
mainWindow.showFullScreen();
MainWindow extend of QMainWindow.
You want to setWindowFlags
, with Qt::FramelessWindowHint
and Qt::CustomizeWindowHint
. So mainWindow->setWindowFlags(Qt::CustomizeWindowHint | Qt::FramelessWindowHint)
should work for you.
