Is there a way to create shadow like qgraphicsdropshadoweffect? Because the qgraphicsdropshadoweffect have great impact on PC performance. I tried set boarder radius (stylesheet) but it doesnt look good. Im creating a multiple buttons on a stackwidget and each of it has qgraphicsdropshadoweffect like you guys see on a POS (especially on food). Im using qt 4.7.3.
