Subject: [osg-users] BUG?: mouse coordinate changes after window move
Im using a recent svn version (a few weeks old) of osg under windows (both
VISTA and XP).
I have noticed that if I:
1. Start osgviewer cow.osg
2. press 'f' to get into windowed mode
3. if I now move the whole window and release it, I can see that the
view/projection changes slightly.
A small app that output the coordinates of a mouse click in the window
1. start that application and make it windowed 'f'
2. click on a specific point in the scene, ea.getX (), ea.getY() reports:
3. move the window a little bit, click in the same point in the scene
ea.getX(), ea.getY() reports: (139 ,121)
4. move the window again to any position on the screen, and now ea.getX (),
ea.getY() reports consistent results.
So to me it seems that the first move-window messes (or corrects) the
Now I tried this on a ubuntu machine, but on that one the windowed mode did
not work at all.
Pressing 'f' results in a brief flicker of the window, and I can for a
fraction of a second see a smaller cow, no window decoration in the lower
left corner of the display.
Anyone else noticed these two problems?
