示例1: IsOnTop
/**
* Returns true if view would be drawn on top of comparedWith or false otherwise.
* view and comparedWith are siblings with the same parent. This uses the logic
* that dispatchDraw uses to determine which View should be drawn first.
*/

/* [in] */ IView* comparedWith)

// view is on top.
