Hi Robert,
It's good to hear those news ;-)
I'm currently having another problem on removing view (OSG 2.5.2).
When closing a view in function
void GraphicsContext::close(bool callCloseImplementation)
at line 469
if (makeCurrent()) is returning false.
False is returned from this workaround added 2008/05/12 in
GraphicsWindowWin32::makeCurrentImplementation()
if( ::wglGetCurrentDC() != _hdc ||
::wglGetCurrentContext() != _hglrc )
{
if (!::wglMakeCurrent(_hdc, _hglrc))
{
reportErrorForScreen("GraphicsWindowWin32::makeCurrentImplementation() -
Unable to set current OpenGL rendering context", _traits->screenNum,
::GetLastError());
return false;
}
}
I wish to know if it is the normal behaviour ?
Kind regards,
