The CTabView class simplifies the use of the tab control class ( ) in applications that use MFC's document/view architecture.
class CTabbedView : public CView
Public Methods
Name | Description |
|---|
| Adds a new view to the tab control. |
| Returns the index of the specified view in the tab control. |
| Returns a pointer to the currently active view |
| Returns a reference to the tab control associated with the view. |
| Removes the view from the tab control. |
| Makes a view active. |
Protected Methods
Name | Description |
|---|
| Called by the framework when creating a tab view to determine whether the tab view has a shared horizontal scroll bar. |
| Called by the framework when the tab view is made active or inactive. |
使用CTabView要特别注意获取视图的指针的操作，一般的途径获取只能获取CTabView里面的当前View不能获取到CTabView指针，必须通过下面方法获取，以下为在主框架获取CTabView视图指针的示例：
void CMainFrame:: OnGetBlog()
{
CChildFrame * pChildFrm = ( CChildFrame *) GetActiveFrame();
CView * pView = pChildFrm-> GetActiveView();
CMFCTabCtrl * pParent1 = ( CMFCTabCtrl *) pView-> GetParent();
CXXXTabView * pTabView =( CXXXTabView *) pParent1-> GetParent();
pTabView-> OnBlog(); //调用CTabView视图类里面的函数
}
要禁止CTabView里面的Tab拖动，只需要在CTabView里面调用下面：
this -> GetTabControl().EnableTabSwap( FALSE );
一些CTabView样式设置，如下：
void CXXXTabView:: OnInitialUpdate()
{
CTabView:: OnInitialUpdate();
AddView ( RUNTIME_CLASS ( CView1), _T( " simple " ), 100 );
this -> GetTabControl().SetLocation( CMFCTabCtrl:: LOCATION_TOP); //方向上顶
this -> GetTabControl().ModifyTabStyle( CMFCTabCtrl:: STYLE_3D_ONENOTE); //风格
this -> GetTabControl().EnableAutoColor( TRUE ); //自动着色
this -> GetTabControl().SetTabBorderSize( 2 ); //边框大小
this -> GetTabControl().HideSingleTab( TRUE ); //单个Tab时候不显示Tab标签
this -> GetTabControl().EnableTabSwap( FALSE ); //禁止拖动
}
若是要禁止CTabView上的滚动条，只要在CTabView的头文件上，定义以下函数即可：
BOOL IsScrollBar () const
{
return FALSE ;
}
在基于CTabView的多文档中，遍历每个CTabView视图可以通过获取框架指针。下面是关闭除当前视图外的其余视图：
void CMainFrame::OnFileAllClose()
{
CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
CMDIChildWnd *pChild = (CMDIChildWnd*)pFrame->GetActiveFrame();
CView * pView;
CMFCTabCtrl * pParent1;
CXXXTabView * pTabView;
CDocument* pDoc;
CMDIChildWnd *pChild2=pFrame->MDIGetActive();
if (pFrame)
{
//依次关闭右边视图
pFrame->MDINext();
pChild2=pFrame->MDIGetActive();
while (pChild2!=pChild)
{
pView = pChild2->GetActiveView();
pParent1 = (CMFCTabCtrl *)pView->GetParent();
pTabView =(CXXXTabView *) pParent1->GetParent();
pDoc = pTabView->GetDocument();
pDoc->OnCloseDocument();
pChild2=pFrame->MDIGetActive();
}
//依次关闭左边视图
pFrame->MDIPrev();
pChild2=pFrame->MDIGetActive();
while (pChild2!=pChild)
{
pView = pChild2->GetActiveView();
pParent1 = (CMFCTabCtrl *)pView->GetParent();
pTabView =(CXXXTabView *) pParent1->GetParent();
pDoc = pTabView->GetDocument();
pDoc->OnCloseDocument();
pFrame->MDIPrev();
pChild2=pFrame->MDIGetActive();
}
}
}
