My toolbar is covered by my OpenGL scene...
Author
Hi,
I have a CFrameWnd-window in which I render the scene. I added a dockable toolbar but it is not visible in the docked state because my scene is rendered in the whole client area, also over the toolbar. When I click the location of a button in the toolbar, the button appears for one frame and then disapears again.
What I tried doing to solve this problem is to use GL_SCISSOR_TEST to avoid drawing over the docked toolbar.
But it seems that the SwapBuffers(hDC) command swaps the entire client aera and the problem remains.
Any idea how to solve my problem?
Thanks
Not sure what the problem is, but just make sure you WS_VISIBLE when making your toolbar.

Thank you,
The WS_VISIBLE flag is set (and if I don''t SwapBuffers(hDC) my toolbar appears and is working fine).
I think it is rather a problem with SwapBuffers(hDC). Could a specify a smaller swapping area than the client area amybe?

Just found something:
SwapBuffers(GetDCEx(NULL,DCX_CLIPCHILDREN)->m_hDC);
The GetDCEx function allows to exclude the areas occupied by children from the client area.
Also
SwapBuffers(GetDCEx(®ion,DCX_EXCLUDERGN)->m_hDC);
should have the same effect but with a user-defined area.
I tested both, but it seems it has no effect...

I found it!
I simply had to specify the WS_CLIPCHILDREN-flag when creating my window!
Now my toolBar is always on top. But the rendering still ''thinks'' it can render onto the whole client area: the top and bottom of my scene is cut by the toolBar and statusBar. Any way to overcome this without using viewports?

Thank you wild_pointer,
I looked into PreCreateWindow but I have no clue about what to do there... Can you give me a clue please? I am not an experienced MFC programmer
