利用DOTNETBAR制作圆角窗体和圆角控件

1、

如果制作圆角窗体，窗体先继承DOTNETBAR的：public partial class Form2 : DevComponents.DotNetBar.Office2007Form

然后窗体里加上一个DONTERBAR的panel，然后设置panel为fill占满整个窗体

然后设置panel的CornerType为Rounded，然后窗体就变为圆角的了： panelEx1.Style.CornerType = DevComponents.DotNetBar.eCornerType.Rounded;

2、

如果是圆角控件就照葫芦画瓢，把panel放在控件上面，然后设置为fill，再设置panel的CornerType为Rounded就变为圆角控件了

DOTNETBAR的button控件默认就可以设置为圆角按钮的

今天弄个了一天最后弄出了圆角窗体，可是不是用DOTNETBAR，原来DOTNETBAR实现不了，以下是本人实现圆角窗体的代码

  /// <summary>
        /// 重绘窗体为圆角
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void DispenserForm_Paint(object sender, PaintEventArgs e)
        {
            Form form = ((Form)sender);
            List<Point> list = new List<Point>();
            int width = form.Width;
            int height = form.Height;

            //左上
            list.Add(new Point(0, 5));
            list.Add(new Point(1, 5));
            list.Add(new Point(1, 3));
            list.Add(new Point(2, 3));
            list.Add(new Point(2, 2));
            list.Add(new Point(3, 2));
            list.Add(new Point(3, 1));
            list.Add(new Point(5, 1));
            list.Add(new Point(5, 0));
            //右上
            list.Add(new Point(width - 5, 0));
            list.Add(new Point(width - 5, 1));
            list.Add(new Point(width - 3, 1));
            list.Add(new Point(width - 3, 2));
            list.Add(new Point(width - 2, 2));
            list.Add(new Point(width - 2, 3));
            list.Add(new Point(width - 1, 3));
            list.Add(new Point(width - 1, 5));
            list.Add(new Point(width - 0, 5));
            //右下
            list.Add(new Point(width - 0, height - 5));
            list.Add(new Point(width - 1, height - 5));
            list.Add(new Point(width - 1, height - 3));
            list.Add(new Point(width - 2, height - 3));
            list.Add(new Point(width - 2, height - 2));
            list.Add(new Point(width - 3, height - 2));
            list.Add(new Point(width - 3, height - 1));
            list.Add(new Point(width - 5, height - 1));
            list.Add(new Point(width - 5, height - 0));
            //左下
            list.Add(new Point(5, height - 0));
            list.Add(new Point(5, height - 1));
            list.Add(new Point(3, height - 1));
            list.Add(new Point(3, height - 2));
            list.Add(new Point(2, height - 2));
            list.Add(new Point(2, height - 3));
            list.Add(new Point(1, height - 3));
            list.Add(new Point(1, height - 5));
            list.Add(new Point(0, height - 5));

            Point[] points = list.ToArray();

            GraphicsPath shape = new GraphicsPath();
            shape.AddPolygon(points);

            //将窗体的显示区域设为GraphicsPath的实例
            form.Region = new System.Drawing.Region(shape);
        }
