Adding a another View/Frame to a document

My document has multiple views. I am adding another view whose frame class is different and it initial size comes up to zero (just the title bar of the window shows up).

Code:

---

        CChildFrame* pNewFrame = (CChildFrame*) theApp.m_pMyDocTemplate->CreateNewFrame( pDoc, pFrame );

        // create new view
        if (pNewFrame != NULL )
            pNewFrame->InitialUpdateFrame(pDoc, TRUE);

---

I have other views added too and they work fine. I know the difference is that these other views have the same CFrameWnd in the CMultiDocTemplate but this new view has a difference frame class

Code:

---

m_pTestDocTemplate = new CMultiDocTemplate(
        IDR_MAINFRAME,
        RUNTIME_CLASS(CTestDoc),
        RUNTIME_CLASS(CChildFrame),
        RUNTIME_CLASS(CTestView));
    AddDocTemplate(m_pTestDocTemplate);

m_pTest2DocTemplate = new CMultiDocTemplate(
        IDR_MAINFRAME,
        RUNTIME_CLASS(CTestDoc),
        RUNTIME_CLASS(CChildFrame),
        RUNTIME_CLASS(CTest2View));
    AddDocTemplate(m_pTest2DocTemplate);

m_pTest3DocTemplate = new CMultiDocTemplate(
        IDR_MAINFRAME,
        RUNTIME_CLASS(CTestDoc),
        RUNTIME_CLASS(CChildCustomFrame), // custom MDI child frame
        RUNTIME_CLASS(CTest3View));
    AddDocTemplate(m_pTestDocTemplate);

---

As you can see from the definitions, when I add m_pTest2DocTemplate it works fine because the CChildFrame is the same but adding m_pTest3DocTemplate starts the new view in zero size perhaps because of different frame class?

What is the strategy to add the view if their is a different frame class involved as well? The custom frame class that I am using controls the sizing requirements of the view in my case.

Hi,

Can you tell us a little bit more about the error you get? Is there a compile time error or a runtime error (Assertion possibly?)?

If you get an assertion step into the MFC code. Often you'll see what happened and why the assertion came up.

With regards

What the heck...I hope you have mistyped the code here...or else...

Code:

---

m_pTestDocTemplate = new CMultiDocTemplate(
        IDR_MAINFRAME,
        RUNTIME_CLASS(CTestDoc),
        RUNTIME_CLASS(CChildFrame),
        RUNTIME_CLASS(CTestView));
    AddDocTemplate(m_pTestDocTemplate);

m_pTest2DocTemplate = new CMultiDocTemplate(
        IDR_MAINFRAME,
        RUNTIME_CLASS(CTestDoc),
        RUNTIME_CLASS(CChildFrame),
        RUNTIME_CLASS(CTest2View));
    AddDocTemplate(m_pTest2DocTemplate);

m_pTest3DocTemplate = new CMultiDocTemplate(
        IDR_MAINFRAME,
        RUNTIME_CLASS(CTestDoc),
        RUNTIME_CLASS(CChildCustomFrame), // custom MDI child frame
        RUNTIME_CLASS(CTest3View));
    AddDocTemplate(m_pTestDocTemplate);

Did u find the error yet? In the third doc template, u r adding the reference to the first doc template. I believe this is the error...
Just change m_pTestDocTemplate in 3rd case to m_pTest3DocTemplate...

Sorry about it but it is just a typo in the post. I simply renamed the variable names.

I don't get any compiler error. The problem is just that the new view/frame shows in zero size, it's only the title bar you see. I can than resize the window to make it bigger but initital size is just the smallest possible.

My suspiction is confirmed though, if I change the frame class to match it to the rest of the group, my window shows up in proper size.

Code:

---

m_pTest3DocTemplate = new CMultiDocTemplate(
        IDR_MAINFRAME,
        RUNTIME_CLASS(CTestDoc),
        RUNTIME_CLASS(CChildFrame), // CChildCustomFrame
        RUNTIME_CLASS(CTest3View));
    AddDocTemplate(m_pTest3DocTemplate)

But I want to be able to use a new frame class with the new view, how can I do that?

I found the mistake. It was not the fact that it was a different frame. The frame is getting resized to an image displayed in the view but when view is created, the image is not initialized yet - is zero so window size is zero.

I am displaying this image from the document. First I am creating new view/frame and than you use UpdateAllViews() to pass the view to display the image.

The problem is that my frame needs to be adjusted to the image size so I would really like to have access to the image when frame is created. Is there a way I can pass the image to the view at the time of creation?
