MFC构建一个（位图）画刷

CPoint ptOrigin; //定义一个点，用于存储画线的起点void CMapBigView::OnLButtonDown(UINT nFlags, CPoint point) {// TODO: Add your message handler code here and/or call defaultptOrigin = point; //保存CView::OnLButtonDown(nFlags, point);}void CMapBigView::OnLButtonUp(UINT nFlags, CPoint point) {// TODO: Add your message handler code here and/or call defaultCBitmap bitmap; //创建一个位图对象bitmap.LoadBitmap(IDB_BITMAP1); //加载一个位图//CBrush brush(RGB(255,0,0));//创建一个 色彩画刷CBrush brush(&bitmap); //创建一个 位图画刷CClientDC dc(this);dc.FillRect(CRect(ptOrigin, point), &brush);CView::OnLButtonUp(nFlags, point);}
