如何进行视图切换？ 我跟踪下去，一切正常，但是就是视图就是不变（始终为初始化的视图）？（附代码）

Question

在我的一个MDI 程序ReManage中， 定义了几个从CFormView派生的视图：CNoOneParaView，CNoTwoParaView ...;初始化视图为：CNoOneParaView
BOOL CReManageApp::InitInstance() CMultiDocTemplate* pDocTemplate;
pDocTemplate = new CMultiDocTemplate(
IDR_RELAYMTYPE,
RUNTIME_CLASS(CReManageDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame
RUNTIME_CLASS(CNoOneParaView));//初始化的视图 
AddDocTemplate(pDocTemplate);在程序中，我需要根据用户的菜单选择，来切换视图到CNoTwoParaView。以下是用户下达切换菜单后，我的处理过程：
{
CView* pOldActiveView = this->GetActiveView();
CView* pNewActiveView = (CView*) m_pNoTwoParaView ; if (pNewActiveView)
{
           if (pOldActiveView == pNewActiveView) return; SetActiveView(pNewActiveView);
pNewActiveView->ShowWindow(SW_SHOW);
pNewActiveView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
pOldActiveView->ShowWindow(SW_HIDE);
pOldActiveView->SetDlgCtrlID(m_nCurrentViewID);
m_nCurrentViewID = 11; RecalcLayout();
}
}

Answer 1

一个简单的办法:
CloseAllDocuments(false);               
pDocTemplate->OpenDocumentFile(NULL);

Answer 2

看錯了.SetActiveView放在Recalclayout前面.

Answer 3

我試了一下可以的.
void CMainFrame::OnChgview() 
{
CCoolSDIMenuDoc *pDoc=((CCoolSDIMenuView *)GetActiveView())->GetDocument();
    CCoolSDIMenuView *pOldView=(CCoolSDIMenuView *)GetActiveView();
    pDoc->AddView(m_View2) ;
m_View2->ShowWindow(SW_SHOW);
pOldView->ShowWindow(SW_HIDE);
m_View2->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
pOldView->SetDlgCtrlID(AFX_IDW_PANE_FIRST+1);
    SetActiveView(m_View2);
        pDoc->RemoveView(pOldView);
RecalcLayout();
}
class CMainFrame : public CSpawnFrameWnd
{public:
    CSecondView *m_View2;
....
}int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
....
    m_View2=(CSecondView*)RUNTIME_CLASS(CSecondView)->CreateObject();
m_View2->Create(NULL, NULL, WS_CHILD, 
CRect(0,0,0,0), this, IDC_VIEW, NULL);
}

Answer 4

pNewActiveView->SetActiveView();
RecalcLayout();
Invalidate(TURE);

Answer 5

void CMainFrame::OnSwitch() 
{
CView *pView = GetRightPane();
if (pView == NULL)
return; CRuntimeClass *pViewClass = NULL;
if (pView->IsKindOf(RUNTIME_CLASS(CViewSwitchView)))
{
pViewClass = RUNTIME_CLASS(CRightFormView);
}
else if (pView->IsKindOf(RUNTIME_CLASS(CRightFormView)))
{
pViewClass = RUNTIME_CLASS(CViewSwitchView);
}
CRect rc;
pView->GetWindowRect(&rc);
m_wndSplitter.DeleteView(0, 1);
CCreateContext context;
context.m_pCurrentDoc = GetActiveDocument();
context.m_pCurrentFrame = this;
context.m_pLastView = NULL;
context.m_pNewDocTemplate = NULL;
context.m_pNewViewClass = pViewClass;
if (!m_wndSplitter.CreateView(0,1, pViewClass, rc.Size(), &context))
ASSERT(FALSE); m_wndSplitter.RecalcLayout();
}

Answer 6

you can use your code in SDI ,but not in MDI ,you must find active doc

Answer 7

你可以这样：不断地调用GetNextView()
CView* pTempView;
POSITION pos = m_pDoc->GetFirstViewPosition();
while (pos != NULL)
{
pTempView = m_pDoc->GetNextView(pos);
 if(pTempView->IsKindOf(RUNTIME_CLASS(CXXXView)))
}
