圆形窗体
找到窗体的Paint事件,写入以下代码:
private void form1_Paint(object sender, PaintEventArgs e){#region 圆形窗体System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath();//创建一条线path.AddEllipse(0, 0, Width, Height);//画一个椭圆 (x,y,宽,高)Graphics g = CreateGraphics();//为窗体创建画布g.DrawEllipse(new Pen(Color.Black, 2), 1, 1, Width - 2, Height - 2);//为画布画一个椭圆(笔,x,y,宽,高)Region = new Region(path);//设置控件的窗口区域#endregion}
效果:
圆形按钮代码:
public class CircleButton : Button//继承按钮类 重新生成解决方案就能看见我啦{protected override void OnPaint(PaintEventArgs e)//重新设置控件的形状 protected 保护 override重新{base.OnPaint(e);//递归 每次重新都发生此方法,保证其形状为自定义形状System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath();path.AddEllipse(2, 2, this.Width - 6, this.Height - 6);Graphics g = e.Graphics;g.DrawEllipse(new Pen(Color.Black, 2), 2, 2, Width - 6, Height - 6);Region = new Region(path);}}
重新生成解决方案后工具箱出现我们的自定义按钮
