Hi,
GraphicsWindowWin32::setWindow currently creates a context with no regards to
the Traits, like createWindow does.
That is, it calls ::wglCreateContext to create a context, not the member method
createContextImplementation(), which takes into an account the Traits.
In my situation, this prevents a GL 3.x context from being created.
Therefore I think the code should read:
Code:
bool GraphicsWindowWin32::setWindow( HWND handle )
{
if (!setPixelFormat())
{
reportErrorForScreen("GraphicsWindowWin32::setWindow() - Unable to set
the inherited window pixel format", _traits->screenNum, ::GetLastError());
::ReleaseDC(_hwnd, _hdc);
_hdc = 0;
_hwnd = 0;
return false;
}
// -- wrong
//_hglrc = ::wglCreateContext(_hdc);
// ++ correct
_hglrc = createContextImplementation();
if (_hglrc==0)
{
reportErrorForScreen("GraphicsWindowWin32::setWindow() - Unable to
create OpenGL rendering context", _traits->screenNum, ::GetLastError());
::ReleaseDC(_hwnd, _hdc);
_hdc = 0;
_hwnd = 0;
return false;
}
}
Cheers,
Fred
