Commit some work I've done while toying with port of Kollision to QGV I started to port many Message to be one QGraphicsTextItem but abandoned that at the point when I've seen that it should be SharedPtr. So it is now in a state of flux.

Also ball doesn't know its radius now and all coords set upper-left corner coords, not center of ball. This mainly affects MainArea (I think I fixed all cases).

And glitches are not tracked down yet

The best way to use this branch is:

cd playground/games/kollision
svn switch svn+ssh://USERNAME@svn.kde.org/home/kde/branches/work/kollision-qgv
make && make install

Good luck! :-)
