Class HoverTracker

  • public class HoverTracker
extends java.lang.Object
    This class is an overly complex way to do something that you think should be simple. It calls callbacks when the mouse hovers over a component and another when it exits. This could be done easily with a MouseListener but unfortunately that strategy only works for simple components with no children. This implementation puts mouse listeners on the given component and all children, and tracks whenever the mouse is anywhere in the interior of the outermost component. Note that the tracker does not handle the case where the children are altered after the tracker is created, so make the tracker after the UI has been initialized.
