C＃我有一个带背景图片的按钮。如何在一定条件下触发mouseleave事件？

问题描述

我有一个带背景的按钮。我创建了mouseenter& mouseleave事件。在mouseleave事件中，如果鼠标光标在2个坐标之外，它将触发mouseleave事件。



我的问题是当我离开500X250矩形时，它会触发mouseleave。我希望它能在250X125矩形中触发。



我尝试过：

I have a button with a background. I created mouseenter & mouseleave event. In the mouseleave event, if a mouse cursor is outside of 2 coordinates it will trigger the mouseleave event.

my problem is when i leave in 500X250 rectangle, it will trigger the mouseleave. i want it to trigger in 250X125 rectangle.

What I have tried:

private void Button_SpanMouseEnter(object sender, EventArgs e)
    {
        Button x = sender as Button;
        x.Size = new Size(500, 250);
        x.Location = new Point(0, 0);
    }

    private void Button_SpanMouseLeave(object sender, EventArgs e)
    {
        Button x = sender as Button;

        //If cursor is outside of this coordinates(0,0) & (250,125)
        //it will trigger this size
        x.Size = new Size(250,125);
        x.Location = new Point(0, 0);
    }
