EnableOffice2007Frame OpenGL refresh question

Product: Xtreme Toolkit (MFC) version 13.0.0
Platform: Windows Vista (64bit) - SP 1 (running CodeJock and program  in 32bit mode)
Language: C++

Hi,

I have created an MDI application with an MFC OpenGL window within each child window.  I am using the Office 2007 frame on the parent window with no problems, but as soon as I call EnableOffice2007Frame on the creation of the child windows, I have issues with the inner window refreshing correctly when moving it around, going between the MDI child windows, etc. (see picture below).  I don't have this problem at all if I don't use the framing on the child windows.  However, for the sake of consistency, I would really like the inner windows to be framed the same way as the parent.  Any ideas?

Thanks!

Hi Adrien,

No, I don't believe so -- at least I didn't explicitly create any new threads.  They are VTK render windows <vtkWin32OpenGLRenderWindow>, if that clarifies things any (http://www.vtk.org/doc/release/5.2/html/a01538.html).

As long as I don't put the Office2007 frames on the child windows, the inner windows render/update correctly, and everything works perfectly.  The  only difference in the code is within the ChildFrame::OnCreate(LPCREATESTRUCT lpCreateStruct), the very last line I added: 

EnableOffice2007Frame(this, ((CXTPMDIFrameWnd*)GetParentFrame())->GetCommandBars()->GetPaintManager());


Thanks for your help.

They do have the WS_CLIPSIBLINGS style.  I'll  take a closer look at that. 

Thanks!

I found you need a thread per frame if you want it all to work properly, else onidle processing doesn't happen and you don't get lots of things updating.

I just spawn a new thread and create the window in its initialiser.

Take a look at this:

I'm evaluating an OpenGL-crafted component for my software. I found a very interesting setting in this component:

class CGUIWorker : public CWinThread
{
public:
     CGUIWorker(CMyFrame* pFrame)
     {
          m_pMainWnd = pFrame;
     }
     virtual BOOL InitInstance()
     {
          OleInitialize(NULL);
          ((CMyFrame*)m_pMainWnd)->Create(NULL, "Some name", WS_OVERLAPPEDWINDOW | WS_VISIBLE);
          // bring new frame to foreground
          m_pMainWnd->SetForegroundWindow();
          return TRUE;
     }
     virtual int ExitInstance()
     {
          return 0;
     }
     DECLARE_MESSAGE_MAP()
};

BEGIN_MESSAGE_MAP(CGUIWorker, CWinThread)
END_MESSAGE_MAP()

to spawn a window you then do something like

CGUIWorker* pWorker = new CGUIWorker(new CMyFrame());
pWorker->CreateThread();

you'll need to change the call to Create in InitInstance to whatever kind of create you want.

You will also need to implement a PostNCDestroy func in your frame class...

void CMyFrame::PostNcDestroy( )
{
     // tell the thread that created this frame to terminate
     ::PostThreadMessage(::GetCurrentThreadId(), WM_QUIT, 0, 0);

     CXTPFrameWnd::PostNcDestroy();
}

Hi again adrien,

I'm just now having the time to implement the threading code that you provided earlier.  I have one question, though.  Do I spawn off a new thread in the initialization of each MDI child frame or in the init of each actual OpenGL window within that frame?

Thanks for your continued help!

Hmm, I actually ran into this issue today. Did you find a final solution to it?

Hi znakeeye,

I had basically given up on this problem, hoping that it was something that Codejock would be able to fix in future releases.  I'm using a third party component as well; in fact, we may actually be using the same one.  Can you explain what you mean by "recreate the OpenGL context" or provide an example of doing that?

Thanks!
