How to set the shadow around the window

I need to show shadow around my mainWindow and I cannot set WA_TranslucentBackground on it as I need to show a video.

How do I set a shadow for QMainWindow without making it transparent?

You need to :

  1. Create top level QWidget

  2. Make it translucent and frameless

    setWindowFlags(Qt::FramelessWindowHint);    
setAttribute(Qt::WA_TranslucentBackground);

  3. Insert your MainWindow into created widget. Left some margins for shadow (about 5-15 px)

  4. Add QGraphicsDropShadowEffect to MainWindow:

    QGraphicsDropShadowEffect *wndShadow = new QGraphicsDropShadowEffect;
wndShadow->setBlurRadius(9.0);
wndShadow->setColor(QColor(0, 0, 0, 160));
wndShadow->setOffset(4.0);
mainWindow->setGraphicsEffect(wndShadow);

Result:

A widget with drop shadow
