Hi,

I have derived a class hvlOpenGLWnd from CWnd to display OpenGL.

I have created a pane:

CXTPDockingPane* _pPane = _pPaneManager->CreatePane(HVL_ID, CRect(0, 0, 140, 600), xtpPaneDockBottom);

I have created a window:

hvlOpenGLWnd m_Wnd;

m_Wnd.Create (_T("STATIC"), L"Hi", WS_CHILD | WS_VISIBLE,CRect(0, 0, 140, 600), _pMainWnd, 1234);

and attached the window:

_pPane->Attach(&m_Wnd);

How to make the CWnd fit in the pane when I resize the pane? With the current code, changing the pane size with the mouse will not resize the window. The Window always stays 140x600.

Thanks,

HVL

how about catching WM_SIZE in your hvlOpenGLWnd and adjusting the glViewport ? Worked for me..

void CGLWnd::OnSizeGL(int cx, int cy)
{
// set correspondence between window and OGL viewport
glViewport(0, 0, cx, cy);
}

Thanks, for some reason my message Map was wrong, your reply helps me to detect the problem. Especially since Microsoft debugger does not want to correlate the source code to the binary therefore I can't debug... Something I need to investigate in order to continue my development.
