[求助]怎么样才能实现窗口切换时实现重绘?
void CText5_1View::OnLButtonDown(UINT nFlags, CPoint point) {
// TODO: Add your message handler code here and/or call default
m_iPointIndex = point;
CClientDC dc(this);
dc.Rectangle(point.x -30,point.y-30,point.x+20,point.y+20);
CView::OnLButtonDown(nFlags, point);
}
麻烦大家帮我看一下~~谢谢了!怎样才能实现窗口的切换啊? 最大化后画的图就没有了.
