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;
}
