按钮周围的浅蓝色边框 [英] light blue border around button

问题描述

在Winforms中，看起来像焦点的按钮有一个浅蓝色边框。

In Winforms, it looks like the button which has focus has a light blue border.

在我的表单中有两个按钮，当表单首次加载时，button1有焦点并有一个浅蓝色边框。

In my form which has two buttons, when the form first loads, button1 has focus and has a light blue border.

点击button2后，它有一个浅蓝色边框。

After I click on button2, it then has a light blue border.

我可以将淡蓝色更改为其他颜色吗？

Can I change the light blue to a different color?

推荐答案

我认为没有一个简单的属性（有人可能会纠正我），但你可以使用Paint事件。 / p>

I don't think there's a simple property for that (someone might correct me), but you can use the Paint event.

      private void button1_Paint(object sender, PaintEventArgs e)
      {
         Button b = sender as Button;
         if (b.Focused)
         {
            e.Graphics.DrawRectangle(new Pen(Color.Red), new Rectangle(e.ClipRectangle.Left, e.ClipRectangle.Top, e.ClipRectangle.Width - 1, e.ClipRectangle.Height - 1));
         }
      }
