You could use a timer tick event instead of mouse leave.
Mouse enter would start the timer and when the mouse leaves the control, the
timer tick event would stop the timer. So the timer only runs when the mouse
is in the control.
It's easier to show a simple example than try to explain. This is for a
normal Form with a panel and a timer dropped on it. // the smaller the timer
interval the faster it works.
//--------------------------------------------------------------------
private void panel1_MouseEnter(object sender, System.EventArgs e)
{
panel1.BackColor = Color.Blue;
timer1.Start();
}
//--------------------------------------------------------------------
private void timer1_Tick(object sender, System.EventArgs e)
{
Point p = new Point(0,0);
p = panel1.PointToScreen(p);
Rectangle r = new Rectangle(p, panel1.ClientSize);
p = Cursor.Position;
if(r.Contains(p) == false)
{
panel1.BackColor = Color.Red;
timer1.Stop();
}
}
