MDI中如何判断鼠标点击在子窗体之外？

Answer 1

这样好象可以BOOL CMainFrame::PreTranslateMessage(MSG* pMsg) 
{ if(WM_LBUTTONDOWN == pMsg->message) { CFmView *pFmView ;
pFmView = (CFmView*)GetActiveFrame()->GetActiveView(); if (pFmView == NULL) {
return FALSE;
} CRect   rect;   
pFmView->GetClientRect(rect);
ClientToScreen(rect);

CPoint point;
::GetCursorPos(&point);
ScreenToClient(&point);

BOOL curIn = FALSE;
if(rect.PtInRect(point)   ) {   
curIn = TRUE;     
}   

//其他处理
}

return CMDIFrameWnd::PreTranslateMessage(pMsg);
}
