Hi all,

I'm running QML on embedded device (IPTV set-top box) which has separate 
hardware layer fo video output, placed under UI layer where QML paints.

Now I'd like create QML item providing transparent "hole", i.e. transparent 
rect hich would not blend with content underneath, but "erasing" it (so that 
video layer becomes unobscured).

In widgets API I could draw transparent rect with QPainter using 
CompositionMode_Clear. Is it possible to achieve the same thing in QML? 
Solution (ab)using private APIs is acceptable for me.

Konstantin
