如何在 C# 中创建热点? [英] How to create HotSpot in C#?

问题描述

我想在我的 winform 应用程序中创建一个图像热点.我遵循了HERE发布的解决方案，但我不知道应该把坐标使此方法起作用:

I want to create a hotspot on image in my winform application. I followed the solution posted HERE, but I don't know where I should put the coordinates to make this method work:

protected override void OnMouseMove(MouseEventArgs mouseEvent) 
{ 
     string X = mouseEvent.X.ToString();
     string Y = mouseEvent.Y.ToString(); 
}

我应该把坐标放在哪里?我有两个坐标 (X,Y): 110, 45

Where should I put the coordinates? I have two coordinates (X,Y): 110, 45

推荐答案

如果您想响应鼠标悬停在 矩形 在图像中:

If you want to respond to the mouse being over a rectangle within the image:

private Rectangle _hotspot = new Rectangle(20, 30, 10, 10);

protected override void OnMouseDown(MouseEventArgs e)
{
    if (e.Button == MouseButtons.Left)
    {
        if (_hotspot.Contains(e.Location))
        {
            // respond to the mouse being in the hotspot
        }
    }
}
