how do you use the QPropertyAnimation to effect opacity on a widget?

As you said proxy is a widget, widget has property windowOpacity.

If you use graphicsItem, property would be opacity

In your case, setOpacity is a function, not property.

Hi thanks for your help.

I used " opacity" and it worked great...but I'm a little confused because it is a proxy widget that I add to a graphic scene.

So if opacity worked then that means it must be a graphics item correct? Some other poster said a proxy widget inherits from a graphics widget.
