C＃停止按键从上点击获得焦点 [英] C# Stop Button From Gaining Focus on Click

问题描述

我有几个按钮，点击时，我不希望他们获得焦点我也不希望再空格键为preSS'他们。

我想相同的功能在Windows计算器的按钮。

Google搜索和搜索堆栈一切似乎是有关表单如。 制作形式在C＃不可作为焦点

我知道我应该重写的WndProc，但不完全知道如何着手，以我应该抓住什么样的信息/忽略等。据我得到的答案：

 保护覆盖无效的WndProc（参考消息M）
    {
        base.WndProc（REF米）;
    }
 

解决方案

所有你要做的就是这一行添加到关键的点击活动结束：

  this.Focus（）;
 

这条线将导致按钮失去焦点，窗体将获得焦点和空格不会有任何影响，从而满足您的2个条件。

现在，如果你不想让按钮能够再次点击，然后添加这两条线来代替：

  this.Focus（）;
（（按钮）发送方）.Enabled = FALSE;
 

这将做什么其他行做，此外，它会禁用按钮。

I have several buttons that when clicked I don't want them to get focus nor do I want the space bar to 'press' them again.

I want the same functionality as the buttons in windows calculator.

Googled and searched stack everything seems to be about forms eg. Make a form not focusable in C#

I know I'm supposed to rewrite WndProc but not exactly sure how to proceed as to what messages I should catch/ignore etc. As far as I got:

protected override void WndProc(ref Message m)
    {
        base.WndProc(ref m);
    }

解决方案

All you got to do is add this line to the end of the key's Click event:

this.Focus();

This line will cause the button to lose focus, the form will gain focus and spacebar will have no effect, thus satisfying your 2 conditions.

Now if you don't want the button to be able to be clicked again, then add these 2 lines instead:

this.Focus();
((Button)sender).Enabled = false;

This will do what the other line did and in addition, it will disable the button.
