QGraphicsItem disappeare during rotation around Qt::XAxis

I can see the item just fine. Bear in mind that graphics items are flat, if you rotate them 90 deg. they will disappear because their z size is 0.

Hi,
did you try to change window size? if I make it vertically bigger the item disappear and again appear when i make the window smaller.
If you tried it and you still can see it then the problem will be somewhere else, but I have no idea where. I was trying on the different comps with kubuntu and and also on windows. The problem was on all of them.

Hi, you should know what really you want to do. If you only want to rotate the rect, just use QGraphicsItem::rotate(). The transform will rotate the whole coordinate.

Hi,
the code above is just simple example to demonstrate what I mean. I am doing chessboard, so there should be option to zoomin and out and to rotate it. But then is coming the problem which I described above.

so looks like it was a bug, i have tried on qt 4.5 and the transformation is fine
