从面板的MouseEnter和鼠标离开事件和它的子控件 [英] MouseEnter and MouseLeave events from a Panel and its child controls

问题描述

我有一个包含子控件面板。

I have a Panel that contains child controls.

如果我处理小组的MouseEnter和鼠标离开事件，和他的孩子的MouseEnter和鼠标离开事件，这里是提高的顺序：

If i handling the Panel's MouseEnter and MouseLeave events, and his child's MouseEnter and MouseLeave events, here is the order of raising:

Panel.MouseEnter
Panel.MouseLeave
Child1.MouseEnter
Child1.MouseLeave
Panel.MouseEnter
Panel.MouseLeave

但我需要提高的顺序如下：

but i need the following order of raising:

Panel.MouseEnter
Child1.MouseEnter
Child1.MouseLeave
Panel.MouseLeave

这可能吗？

推荐答案

如果你不介意创建一个用户控件（若想面板或其他父容器派生）， 重写你的父母的 OnMouseLeave在方法如下所示。

If you dont mind creating a usercontrol(derived from the panel or other parent container you wish), Override your parent's OnMouseLeave method to look like the following..

protected override void OnMouseLeave(EventArgs e)
{

    if(this.ClientRectangle.Contains(this.PointToClient(Control.MousePosition)))
         return;
    else
    {
        base.OnMouseLeave(e);
    }
}

然后，事件提高将在所要求的顺序。

Then, the event raising will be in the required order.
