MFC在其他类中使用MainFrame中的变量或函数

void CMenuTestView::OnMouseMove(UINT nFlags, CPoint point) { // TODO: 在此添加消息处理程序代码和/或调用默认值 CString strMouse; CMainFrame* pFrm=(CMainFrame*)AfxGetApp()->m_pMainWnd; CStatusBar* pStatus=&pFrm->m_wndStatusBar; if(pStatus) { strMouse.Format(_T("X=%d Y=%d"),point.x,point.y); pStatus->SetPaneText(1,strMouse); } CView::OnMouseMove(nFlags, point); }
