MDI窗口的拆分问题

Question

我的程序是MDI程序,包含了两种不同的视图,分别叫做A,B
我只需要对A类视图进行拆分(左右两部分)
该如何实现呀?

Answer 1

BOOL CChildFrame::OnCreateClient( LPCREATESTRUCT /*lpcs*/,
CCreateContext* pContext)
{
if(!m_wndSplitter.CreateStatic(this,1,2,WS_CHILD|WS_VISIBLE))
{
TRACE("Failed to CreateStaticSplitter\n");
return FALSE;
} if(!m_wndSplitter.CreateView(0,0,RUNTIME_CLASS(Adverse),CSize(275,200),pContext))
{
TRACE("Failed to Create command view pane\n");
return FALSE;
} if(!m_wndSplitter.CreateView(0,1,RUNTIME_CLASS(CMyView),CSize(400,400),pContext))
{
TRACE("Failed to Create preview view pane\n");
return FALSE;
} return TRUE;

mfc深入浅出一书通过改写OnWindowNew实现同源子窗口：
先派生个view: CHexView 然后做两个文档模版，对应原来的view 和CHexView：
CMultiDocTemplate* pDocTemplate;
        pDocTemplate = new CMultiDocTemplate(
                IDR_TEXTTYPE,
                RUNTIME_CLASS(CTextDoc),
                RUNTIME_CLASS(CChildFrame), // custom MDI child frame
                RUNTIME_CLASS(CTextView));
        AddDocTemplate(pDocTemplate);        m_pTemplateTxt = new CMultiDocTemplate(
                IDR_TEXTTYPE,
                RUNTIME_CLASS(CTextDoc),
                RUNTIME_CLASS(CChildFrame), // custom MDI child frame
                RUNTIME_CLASS(CTextView));        m_pTemplateHex = new CMultiDocTemplate(
                IDR_TEXTTYPE,
                RUNTIME_CLASS(CTextDoc),
                RUNTIME_CLASS(CChildFrame), // custom MDI child frame
                RUNTIME_CLASS(CHexView));
然后在需要创建新子窗口时，模仿OnWindowNew的内容：
void CMainFrame::OnWindowText()
{
        CMDIChildWnd* pActiveChild = MDIGetActive();
        CDocument* pDocument;
        if (pActiveChild == NULL ||
           (pDocument = pActiveChild->GetActiveDocument()) == NULL)
        {
            TRACE0("Warning: No active document for WindowNew command\n");
            AfxMessageBox(AFX_IDP_COMMAND_FAILURE);
            return;     // command failed
        }        // otherwise we have a new frame!
        CDocTemplate* pTemplate = ((CTextApp*) AfxGetApp())->m_pTemplateTxt;
        ASSERT_VALID(pTemplate);
        CFrameWnd* pFrame = pTemplate->CreateNewFrame(pDocument, pActiveChild);
        if (pFrame == NULL)
        {
            TRACE0("Warning: failed to create new frame\n");
            AfxMessageBox(AFX_IDP_COMMAND_FAILURE);
            return;     // command failed
        }        pTemplate->InitialUpdateFrame(pFrame, pDocument);
}
void CMainFrame::OnWindowHex()
{
        CMDIChildWnd* pActiveChild = MDIGetActive();
        CDocument* pDocument;
        if (pActiveChild == NULL ||
           (pDocument = pActiveChild->GetActiveDocument()) == NULL)
        {
            TRACE0("Warning: No active document for WindowNew command\n");
            AfxMessageBox(AFX_IDP_COMMAND_FAILURE);
            return;     // command failed
        }        // otherwise we have a new frame!
        CDocTemplate* pTemplate = ((CTextApp*) AfxGetApp())->m_pTemplateHex;
        ASSERT_VALID(pTemplate);
        CFrameWnd* pFrame = pTemplate->CreateNewFrame(pDocument, pActiveChild);
        if (pFrame == NULL)
        {
            TRACE0("Warning: failed to create new frame\n");
            AfxMessageBox(AFX_IDP_COMMAND_FAILURE);
            return;     // command failed
        }        pTemplate->InitialUpdateFrame(pFrame, pDocument);
}这样就产生了两个同源子窗口，你如果要将其中之一拆分，另一个不拆分
可以把不拆分的文档模板直接用CMDIChildWnd 产生，需要拆分的用CChildFrame,然后在其中用CSplitterWnd

Answer 3

我刚找到一个解决方案:
在OnCreateClient函数中
if pContext->m_pNewViewClass->m_lpszClassName == 'a'
    拆分
else
   不拆分

Answer 4

成功解决MDI+多视+拆分,解决办法如下:
BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) 
{
// TODO: Add your specialized code here and/or call the base class
const char* pszViewName = "CModuleView";
if (strcmp(pszViewName, pContext->m_pNewViewClass->m_lpszClassName) == 0) 
{
if (!m_wndSplitter.CreateStatic(this, 1, 2) || \
!m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CModuleView),CSize(230, 0), pContext) || 
!m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CModuleView),CSize(0, 0), pContext)) 
{
return FALSE;
}
else
return TRUE;
}
return CMDIChildWnd::OnCreateClient(lpcs, pContext);
}
