This package contains extensions of Swing components that must be able to show their tooltips on the right place in a multimonitor-environment when the parent Window spans more than one monitor. Then the Window's GraphicConfiguration device (that provides bounds for e.g. maximizing) might not reflect the monitor the tooltip of some button shows on (because he is implemented to do such a check, maybe Sun will fix this sometimes).

If you have a Swing application that does not ever span more than one monitor, you do not need this workaround. When your application sometimes overlaps into another monitor, you might need this workaround.
