window. This breaks rendering in for example MFC SDI applications and in
MFC MDI applications if user resizes the window so that client area has
zero height. Current safeguard for minimized window:
LRESULT GraphicsWindowWin32::handleNativeWindowingEvent( HWND hwnd, UINT
uMsg, WPARAM wParam, LPARAM lParam )
...
/////////////////
case WM_MOVE :
case WM_SIZE :
/////////////////
...
if (clientRect.bottom==0 && clientRect.right==0)
...
does not cover this situation. In these situations clientRect.bottom = 0
and clientRect.right > 0.
Quick fix to this is relax condition:
if (clientRect.bottom==0 || clientRect.right==0)
Modified file is attached.
Tested with osgviewerMFC from 2.2.0 release (Windows XP sp2)
Before fix:
- execute from command line osgviewerMFC.exe cow.osg.
- the cow is rendered nicely.
- resize window to zero height by dragging from bottom border upwards.
- resize window back to original height
- just blue screen, no cow
After fix:
- execute from command line osgviewerMFC.exe cow.osg.
- the cow is rendered nicely.
- resize window to zero height by dragging from bottom border upwards.
- resize window back to original height
- the cow is where it is supposed to be.

"This is a fix for the issue reported by Anders a week ago (see \u201c[osg-users] BUG?: mouse coordinate changes after window move\u201d discussion thread on Sept. 20). The issue was that the initial implementation added a few months back was not converting the window coordinates to client-area coordinates resulting in a slight offset each time a decorated window was moved (caused by the window border). This was also causing windows to move out of their assigned screen."

"Attached is a fix for the taskbar repaint issue that occurs when a graphics window is toggled from full-screen mode to windowed mode (as identified by Gert van Maren a couple of weeks ago).
Also included is a fix derived from the \u201cEvents from the past\u201d discussion thread that took place on July 11."
stereo format to work. It's a good thing I tested these on a TV
before submitting them since I did indeed have a bug. One thing I
did not test was to see how this would work in windowed mode. Does
the interlaced stereo code have support for 'absolute' positions?
For example a given pixel on the screen is always shown in a given
eye no matter where the graphics context is placed?
