Eclipse 风格工具提示库？

Does anyone know of an open source swing tooltip library that works like eclipse's tooltips? Specifically, the functionality I'm looking for is a tooltip that acts like a regular tooltip, but persists when you press F2 (or some key) so that you can copy the contents to the clipboard.

Thanks.

没有测试过自己，但也许JCustomTooltip http://prefuse.org/doc/api/prefuse/util/ui/JCustomTooltip.html（基于javax.swing.JToolTip class)
of prefuse.org http://prefuse.org/:

setPersistent(boolean inter) 

设置工具提示是否将持续显示在屏幕上以支持工具提示组件内的交互。

由于源代码可用，因此这可能是编写您自己的版本的起点。
