推荐答案
AbstractPopupGraphMousePlugin及其子类是您想要的: http://jung.sourceforge.net/doc/api/edu/uci/ics/jung/visualization/control/AbstractPopupGraphMousePlugin.html
AbstractPopupGraphMousePlugin and its subclasses are what you want:http://jung.sourceforge.net/doc/api/edu/uci/ics/jung/visualization/control/AbstractPopupGraphMousePlugin.html
请在PluggableRendererDemo和GraphEditorDemo中使用它. (其他示例也使用它；这些示例说明了如何创建子类.)
Look for its use in PluggableRendererDemo and in GraphEditorDemo. (Other samples also use it; those samples show how to create subclasses.)
