MDI多文档模板中tab切换事件消息处理定义

1.头文件定义

   afx_msg LRESULT OnActivateTabChanged(WPARAM,LPARAM);

2.定义消息ON_REGISTERED_MESSAGE(AFX_WM_CHANGE_ACTIVE_TAB,&CMainFrame::OnActivateTabChanged)

3.定义实现

LRESULT CMainFrame::OnActivateTabChanged(WPARAM wParam,LPARAM lParam){CMFCBaseTabCtrl * pTabCtrl = ((CMFCBaseTabCtrl*)lParam);if (pTabCtrl && pTabCtrl->GetSafeHwnd()){int nTabIdx=pTabCtrl->GetActiveTab();CWnd * pWnd = pTabCtrl->GetActiveWnd();if (pWnd && pWnd->GetSafeHwnd()){pWnd->SetForegroundWindow();//激活当前tab}}return 0;}
