Hi,

You can try this QWindow::setMaximumSize(const QSize & size) and set the size or you can even try with window.setWindowState(Qt::WindowMaximized)

I need to set the size of the QWidget to fit the device screen which is Resolution: 1366 x 254, not full screen.

what is the qt command i should use

You can use setMaximumSize(width, height) or setMinimumSize(width, height)
