Question

I would like to delay an action by several seconds after a mouse pointer has entered and remained for period of time in a winform graphics rectangle. What would be a way to do this?

Thanks

c#, .net 2.0, winform

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 😀

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.
