圆形按钮

Question

如何制作圆形按钮而不是传统的矩形按钮.

我正在使用winforms(2.0)

Answer 1

先上课.给它命名圆形按钮.然后直接编写代码:

using System;
using System.Collections.Generic;
using System.Drawing.Drawing2D;
using System.Windows.Forms;
using System.Linq;
using System.Text;

namespace WindowsFormsApplication1
{
    public class RoundButton : Button
    {
        protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
        {
            GraphicsPath grPath = new GraphicsPath();
            grPath.AddEllipse(0, 0, ClientSize.Width, ClientSize.Height);
            this.Region = new System.Drawing.Region(grPath);
            base.OnPaint(e);
        }
    }

}

然后构建您的应用程序并关闭它.现在转到工具箱,您将看到一个名为RoundButton的控件.然后药物并将其放在您的窗体上并测试它......享受!

Answer 2

代码项目中有许多有关这类事情的文章，特别是“ RoundButton Windows Control-Every Decreasing Circles”一文可能引起人们的兴趣，因为它表明您必须执行不同种类的圆形按钮。

Answer 3

GraphicsPath p = new GraphicsPath();
p.AddEllipse(1, 1, button1.Width - 4, button1.Height - 4);
button1.Region = new Region(p);
