教你一招:构造圆角窗体
http://topic.csdn.net/t/20041128/19/3596094.html
增加命名空间:using System.Drawing.Drawing2D;
添加方法如下:当然各角的点可根据需要确定.
复制 保存
private void Type(Control sender, int p_1, double p_2) { GraphicsPath oPath = new GraphicsPath(); oPath.AddClosedCurve( new Point[] { new Point(0, sender.Height / p_1), new Point(sender.Width / p_1, 0), new Point(sender.Width - sender.Width / p_1, 0), new Point(sender.Width, sender.Height / p_1), new Point(sender.Width, sender.Height - sender.Height / p_1), new Point(sender.Width - sender.Width / p_1, sender.Height), new Point(sender.Width / p_1, sender.Height), new Point(0, sender.Height - sender.Height / p_1) }, (float) p_2); sender.Region = new Region(oPath); }
在窗体的paint和resize事件中增加:Type(this,20,0.1);
参数20和0.1也可以根据自己的需要调整到最佳效
