    I want to create a tooltip that appears after a short pause hovering over a button, and stays in the same place, and then disappears (standard stuff right? :) ). I've got it working (sort of), but the code is far more elaborate than what I was expecting. Perhaps there is an easier way? Is this functionality built-in but I just missed it?

    Details of my Method:
    Every time the tooltip changes, record the tooltip, current mouse position, and the time it happened. I then display a tooltip if the proper time has elapsed.

    Code (csharp):
    1.  
    2. if (Event.current.type == EventType.Repaint) {
    3.             if (mLastToolTip != GUI.tooltip) {
    4.                 mLastToolTipHoverStart = Time.time;
    5.                 mLastToolTip = GUI.tooltip;
    6.                 mLastToolTipWidth = GetMinGUIWidth(mLastToolTip);
    7.                 mLastToolTipPosition.x = Input.mousePosition.x - mLastToolTipWidth / 2;
    8.                 mLastToolTipPosition.y = buttonTop - 3*screenPadding;
    9.             }
    10.            
    11.             var deltaTime : float = Time.time - mLastToolTipHoverStart;
    12.             if (mLastToolTip != ""  deltaTime > kDelayUntilToolTipOn  deltaTime < kDelayUntilToolTipOff) {
    13.                 GUI.Label(Rect (mLastToolTipPosition.x, mLastToolTipPosition.y, mLastToolTipWidth, buttonHeight), mLastToolTip);
    14.             }
    15.         }
