显示表单而不窃取焦点?

Show a Form without stealing focus?(显示表单而不窃取焦点?)

问题描述

我正在使用表单来显示通知(它显示在屏幕的右下角)，但是当我显示此表单时，它会从主表单中窃取焦点.有没有办法在不窃取焦点的情况下显示这个通知"表单?

I'm using a Form to show notifications (it appears at the bottom right of the screen), but when I show this form it steals the focus from the main Form. Is there a way to show this "notification" form without stealing focus?

推荐答案

嗯，简单地覆盖 Form.ShowWithoutActivation 还不够吗?

Hmmm, isn't simply overriding Form.ShowWithoutActivation enough?

protected override bool ShowWithoutActivation
{
  get { return true; }
}

如果你也不希望用户点击这个通知窗口，你可以覆盖 CreateParams:

And if you don't want the user to click this notification window either, you can override CreateParams:

protected override CreateParams CreateParams
{
  get
  {
    CreateParams baseParams = base.CreateParams;

    const int WS_EX_NOACTIVATE = 0x08000000;
    const int WS_EX_TOOLWINDOW = 0x00000080;
    baseParams.ExStyle |= ( int )( WS_EX_NOACTIVATE | WS_EX_TOOLWINDOW );

    return baseParams;
  }
}
