Highlight arbitrary widget with blinking background or halo.

  • Hello.
    Suppose I have a widget which has mask and/or gradient as a background color and/or border radius. To highlight it I need a QRegion containing visible part of widget not hovered by other windows (even if it is).
    Is there any way to do it?

    I did some experiments with QPixmap::grabWidget but it doesn't take into account neither mask nor border.
