InitDialog in splitter
-
With MFCm I am trying to create an OpenGL control on a split form the uses the splitter class to create the panes. My problem is I don't know where to put the OnInitDialog() function or how to wire it up. I have a main form CMainFrame and 2 child forms CFormRight and CFormLeft but don't see any place for the OnInitDialog function. The OnCreateClient function in MainForm calls m_splitter.CreateView but not OnInitDialog. Any Suggestions? John C

You seem to need the OnInitialUpdate overrides for your left and right CView derived classes.

Victor, Thanks so much but I still don't know what to do. my CForm right and CFormLeft (where I want to put the OpenGL window) inherit from CFormView. Where do put the over ride? I have CMainForm : public CFrameWnd, and COpenGL: public CWnd. The OnCreateClient() function in CmainForm creates the splitter
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
// TODO: Add your specialized code here and/or call the base class// create splitter window if (!m\_wndSplitter.CreateStatic(this, 1, 2)){ return FALSE; } if (!m\_wndSplitter.CreateView(0, 0, RUNTIME\_CLASS(CFormLeft), CSize(300, 100), pContext) || !m\_wndSplitter.CreateView(0, 1, RUNTIME\_CLASS(CFormRight), CSize(100, 100), pContext)) { m\_wndSplitter.DestroyWindow(); return FALSE; }Thanks. John

Richard, The function that I am trying to get to execute is COpenGLControl::oglInitialize() which was called in OnInitDialog in the example template I am following. the oglInitialize function, listed below should setup the OpenGL context. But my case is somewhat different as you can see from my most recent post and I don't know where to place the call to oglInitalize()
void COpenGLControl::oglInitialize()
{
// Initial Setup:
//
static PIXELFORMATDESCRIPTOR pfd =
{
sizeof(PIXELFORMATDESCRIPTOR),
1,
PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL | PFD_DOUBLEBUFFER,
PFD_TYPE_RGBA,
32, // bit depth
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
16, // z-buffer depth
0, 0, 0, 0, 0, 0, 0,
};// Get device context only once. hdc = GetDC()->m\_hDC; // Pixel format. m\_nPixelFormat = ChoosePixelFormat(hdc, &pfd); SetPixelFormat(hdc, m\_nPixelFormat, &pfd); // Create the OpenGL Rendering Context. hrc = wglCreateContext(hdc); wglMakeCurrent(hdc, hrc); // Basic Setup: // // Set color to use when clearing the background. glClearColor(0.0f, 0.0f, 0.0f, 1.0f); glClearDepth(1.0f); // Turn on backface culling glFrontFace(GL\_CCW); glCullFace(GL\_BACK); // Turn on depth testing glEnable(GL\_DEPTH\_TEST); glDepthFunc(GL\_LEQUAL); // Send draw request OnDraw(NULL);}
In that example template I have three classes CMFCOpenGLDlg : public CDialogEx COpenGLControl : public CWnd and CMFCOpenGLApp : public CWinApp in this example the CMFCOpenGLDlg::OnInitDialog() function calls COpenGLControl::oglCreate() and COpenGLControl::OnCreate() calls COpenGLControl::oglInitialize() but I just don't see how to wire this up in my splitt form example where the panes are created from the splitter class. Thanks, John ... // Create OpenGL Control window m_oglWindow.oglCreate(rect, this);

OK, but you are not calling this from a dialog, but from a CView, so you probably need to call the initializer from the CView::OnInitialUpdate[^] function.
Richard, Thanks for bearing with me. I looked in MDN and found this comment about OnInitialUpdate
Called by the framework after the view is first attached to the document, but before the view is initially displayed.
So I assume that OnInitalUpdate is called automaticaly and I don't need to do anything to invoke it but where would I put the override code in CFormRight : public CFormView or COpenGLControl : public CWnd ? Thanks again, John

Yes, it is called automatically. Note that if you do not override the OnInitalUpdate in your derived class then the base class implementation will be called. And note, that OnInitalUpdate is a method of a CView, not a CDialog. So - override it in CFormRight class.
