Yes you can set it on a QLabel:

http://qt-project.org/doc/qt-5/qwidget.html#setGraphicsEffect

You can set a QGraphicsEffect on a widget, ~~as long as you don't mind it not working on a Mac~~.

label = new QLabel("hello text"));
QGraphicsDropShadowEffect * dse = new QGraphicsDropShadowEffect();
dse->setBlurRadius(10);
label->setGraphicsEffect(dse);

Hope that helps.

I think you're going to be slightly disappointed. To apply an effect, you'll need to use a QGraphicsItem. QLabel isn't. You'll need to use a QGraphicsTextItem inside a QGraphicsScene instead. That probably means you'll need to rebuild your UI if it's already implemented using QWidgets.

QLabel CAN have QGraphicsEffect set DIRECTLY as it is a QWidget! – Петър Петров Aug 07 '13 at 20:31
You can set QGraphicsEffect on the QWidget, but it won't affect the widget's text, and the question is how to apply Glow Effect to QLabel Text and not on QLabel widget. – Uga Buga Oct 21 '13 at 12:28

with proper styling everything is possible. QLabel's brush must have transparent background in order to make Drop Shadows work. – Петър Петров Jan 19 '15 at 20:32
