如何延迟鼠标输入矩形的动作c#

发布于 2024-09-24 18:51:33 字数 101 浏览 3 评论 0原文

我想在鼠标指针进入 winform 图形矩形并在其中停留一段时间后将操作延迟几秒钟。有什么方法可以做到这一点？

感谢

c#、.net 2.0、winform

private Timer timer;
    private void rect_MouseEnter(object sender, EventArgs e)
    {
        timer = new Timer();
        timer.Interval = 3000;
        timer.Start();
        timer.Tick += new EventHandler(t_Tick);

    }

    private void rect_MouseLeave(object sender, EventArgs e)
    {
        timer.Dispose();
    }

    void t_Tick(object sender, EventArgs e)
    {
        timer.Dispose();
        MessageBox.Show(@"It has been over for 3 seconds");
    }

private Timer timer;
    private void rect_MouseEnter(object sender, EventArgs e)
    {
        timer = new Timer();
        timer.Interval = 3000;
        timer.Start();
        timer.Tick += new EventHandler(t_Tick);

    }

    private void rect_MouseLeave(object sender, EventArgs e)
    {
        timer.Dispose();
    }

    void t_Tick(object sender, EventArgs e)

        timer.Dispose();
        MessageBox.Show(@"It has been over for 3 seconds");

诸如此类的事情：

    static void MouseEnteredYourRectangleEvent(object sender, MouseEventArgs e)
    {
        Timer delayTimer = new Timer();
        delayTimer.Interval = 2000; // 2000msec = 2 seconds
        delayTimer.Tick += new ElapsedEventHandler(delayTimer_Elapsed);
    }

    static void delayTimer_Elapsed(object sender, EventArgs e)
    {
        if(MouseInRectangle())
            DoSomething();

        ((Timer)sender).Dispose();
    }

可能可以更有效地完成，但应该可以工作：D

设置 MouseInRectangle -> 的两种方法一种是让它获取当前的鼠标坐标和控件的位置，并查看它是否在其中，另一种方法是在 control.mouse_leave 上将变量设置为 false。

Something such as:

    static void MouseEnteredYourRectangleEvent(object sender, MouseEventArgs e)
    {
        Timer delayTimer = new Timer();
        delayTimer.Interval = 2000; // 2000msec = 2 seconds
        delayTimer.Tick += new ElapsedEventHandler(delayTimer_Elapsed);
    }

    static void delayTimer_Elapsed(object sender, EventArgs e)
    {
        if(MouseInRectangle())
            DoSomething();

        ((Timer)sender).Dispose();
    }

Probably could be done more efficiently, but should work :D

Two ways to set up MouseInRectangle -> one is to make it get the current mouse coordinates and the position of the control and see if it's in it, another way would be a variable which you would set to false on control.mouse_leave.
