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;
}
}
