Yes. It is interesting.
Another way of drawing something transparent is to draw this as "background".
I.e. inside onPaint first draw boxes and then draw text and lines
Hi Yuri,
Yes, my method generates lots of pictures (vpi::pictGetFromWin), which might make the gc sweat a bit on slow computers - maybe?. It was the transparent "drag" across a complex background that I was initially trying to achieve.
cheers
