自定义形状图形，定义几个点围城的图形，然后进行描边和填充：
- if (m_memDC.m_hDC!=NULL)
- {
- CPoint point[4];
- point[0].x=nLeft+(int)(0.1*m_nWidth);
- point[0].y=m_nYmargin;
- point[1].x=nLeft+(int)(0.9*m_nWidth);
- point[1].y=m_nYmargin;
- point[2].x=nLeft+(int)(0.7*m_nWidth);
- point[2].y=(int)(0.2*m_nWidth)+m_nYmargin;
- point[3].x=nLeft+(int)(0.3*m_nWidth);
- point[3].y=(int)(0.2*m_nWidth)+m_nYmargin;
- CBrush br(m_crText); //文字颜色
- CRgn rgn;
- rgn.CreatePolygonRgn(point,4,ALTERNATE); //由所有点围城的不规则矩形
- m_memDC.FillRgn(&rgn,&br); //填充该段
- br.DeleteObject(); //释放画刷
- rgn.DeleteObject();
- m_memDC.MoveTo(point[0]);
- m_memDC.LineTo(point[1]);
- m_memDC.MoveTo(point[1]);
- m_memDC.LineTo(point[2]);
- m_memDC.MoveTo(point[2]);
- m_memDC.LineTo(point[3]);
- m_memDC.MoveTo(point[3]);
- m_memDC.LineTo(point[0]);
- }
