SDI视图分割+多视图问题，请教

pengxiao8 2010-08-05 08:27:09

问题描述：把界面分割为上下两部分，下部分输出操作提示，上部分可以用菜单在4个视图界面间切换，单独实现视图分割和多视图切换都没有问题，把两个合在一起就不行了，表现在：1、界面不能正常切换，2、按最大化程序崩溃，我估计是切换视图后没有更新分割视图，不知道怎么修改
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/, CCreateContext* pContext)
{
// TODO: 在此添加专用代码和/或调用基类
CRect rectClient;
GetClientRect(rectClient);

m_wndSplitter.CreateStatic(this, 2, 1);
m_wndSplitter.CreateView(0, 0, pContext->m_pNewViewClass, CSize(0, rectClient.Height() / 2), pContext);
m_wndSplitter.CreateView(1, 0, RUNTIME_CLASS(CPreviewPane), CSize(0, rectClient.Height() / 2), pContext);

return TRUE;

//return CFrameWndEx::OnCreateClient(lpcs, pContext);
}
void CMainFrame::InitViews ()
{
m_nCurView = 0; // Save index of the currently active view class
CView* pActiveView = GetActiveView();

m_pViews[0] = pActiveView;
m_pViews[1] = (CView*) new CView1;

CDocument* pCurrentDoc = GetActiveDocument();

// Initialize a CCreateContext to point to the active document.
// With this context, the new view is added to the document

CRect rect(0, 0, 0, 0); // gets resized later

for (int nView = 1; nView < NUMVIEWS; nView++)

// Create the new view. In this example, the view persists for
// the life of the application. The application automatically
// deletes the view when the application is closed.
m_pViews[nView]->Create(NULL, NULL,
(AFX_WS_DEFAULT_VIEW & ~WS_VISIBLE),
// views are created with the style of AFX_WS_DEFAULT_VIEW
// In MFC 4.0, this is (WS_BORDER | WS_VISIBLE | WS_CHILD)
rect, this,
AFX_IDW_PANE_FIRST + nView, &newContext);

// When a document template creates a view, the WM_INITIALUPDATE
// message is sent automatically. However, this code must
// explicitly send the message, as follows.
m_pViews [nView]->OnInitialUpdate();
}
}
void CMainFrame::OnOutlookBarShortcut(UINT id)
{
const int nIndex = id ;

ASSERT( nIndex >=0 && nIndex < NUMVIEWS );
if ( nIndex < 0 || nIndex >= NUMVIEWS )
return;

if (!m_pViews)
return;

CView* pNewView = m_pViews[nIndex];
if (!pNewView)
return;

CView* pActiveView =GetActiveView();

if ( !pActiveView ) // No currently active view
return;

if ( pNewView == pActiveView ) // Already there
return;

m_nCurView = nIndex; // Store the new current view's index

// exchange view window ID's so RecalcLayout() works
UINT temp = ::GetWindowLong(pActiveView->m_hWnd, GWL_ID);
::SetWindowLong(pActiveView->m_hWnd, GWL_ID,
::GetWindowLong(pNewView->m_hWnd, GWL_ID));
::SetWindowLong(pNewView->m_hWnd, GWL_ID, temp);

// Display and update the new current view - hide the old one
pActiveView->ShowWindow(SW_HIDE);
pNewView->ShowWindow(SW_SHOW);
SetActiveView(pNewView);
RecalcLayout();
pNewView->Invalidate();

}

用OnOutlookBarShortcut（0）~OnOutlookBarShortcut（3）切换
