订阅MouseMove事件并使用计时器(设置为n ms)来设置超时.每次鼠标移动时,请检查公差.如果超出容差范围,请重置计时器并记录新的原点.

伪代码：

Point lastPoint;
const float tolerance = 5.0;

//you might want to replace this with event subscribe/unsubscribe instead
bool listening = false;

void OnMouSEOver()
{
    lastpoint = Mouse.Location;
    timer.Start();
    listening = true; //listen to MouseMove events
}

void OnMouseLeave()
{
    timer.Stop();
    listening = false; //stop listening
}

void OnMouseMove()
{
    if(listening)
    {
        if(Math.abs(Mouse.Location - lastPoint) > tolerance)
        {
            //mouse moved beyond tolerance - reset timer
            timer.Reset();
            lastPoint = Mouse.Location;
        }
    }
}

void timer_Tick(object sender,EventArgs e)
{
    //mouse "stopped moving"
}
