单文档多视图中如何在MyTreeView中获得MyListView的指针?

Question

在主框架窗口中为每个视添加一个指针成员变量。然后用
((CMainFrame*)AfxGetApp()->m_pMainWnd)->...(指向你的视窗口的成员指针）就可以在任何地方引用你的视了。

Answer 1

可我的View是在程序序中动态分割的呀！m_pMainWnd中没有视窗口的成员指针!
我菜！
能不能不用动态分割创建窗口！

return FALSE; if (!m_wndSplitter.CreateView(0, 0,
RUNTIME_CLASS(CInfoManagerView), CSize(width/3, height), pContext))

找到第一个指定类型的视图
CView* CDoorCtrlApp::FindView(CRuntimeClass* pViewClass)
{
POSITION posDocTemplate=GetFirstDocTemplatePosition();
POSITION posDocument=NULL;
POSITION posView=NULL;
CDocTemplate* pDocTemplate=NULL;
CDocument* pDocument=NULL;
CView* pView=NULL;
while(posDocTemplate){
pDocTemplate=GetNextDocTemplate(posDocTemplate);
posDocument=pDocTemplate->GetFirstDocPosition();
while(posDocument){
pDocument=pDocTemplate->GetNextDoc(posDocument);
posView=pDocument->GetFirstViewPosition();
while(posView){
pView=pDocument->GetNextView(posView);
if(pView->IsKindOf(pViewClass))
return pView;
}
}
}
return NULL;
}
