View Full Version : [C++] Drawing around the mouse cursor

03 March 2011, 09:11 PM
Hello everyone,

I'm trying to draw a visual cue (a circle) around the mouse cursor while it is moving in the viewport.

After much pain and time wasted with maya hacks, I've managed to set up Qt to generate the mouse move events, however, drawing in the overlay plane isn't working (win7 x64, cheap graphics card).

I tried doing it with XorDrawing, but it is inconsistent, sometimes the circle just disappears and it messes with the viewport grid as well, but worst of all, when the mouse exits the viewport, half the circle remains drawn at the point of exit. I've wasted a whole month with this, so any help on how to fix it, or maybe an idea on alternative drawing methods would be greatly appreciated...
Thanks in advance!
