本文介绍如何在Eclipse GEF框架中处理鼠标双击事件。通过重载figure对应的editpart中的performRequest方法，并检查Request的类型为REQ_OPEN来实现。此方法作为回调在SelectEditPartTracker的performOpen方法中被调用。

Ask:
How to add a double click event or Request on a figure?when double click on a figure, a dialog pop up and do some actions.for example when double click on
a UML class figure, a dialog pop up, user can Add a method to the class.
Answer:
This is already done in GEF. Your editpart will receive a performRequest(req) with the type RequestConstants.REQ_OPEN.
See SelectEditPartTRacker#performOpen()

就是在figure对应的editpart中重载方法performRequest(Request req),并判断req的type是否为RequestConstants.REQ_OPEN,如果是,则处理这个双击事件.
这个方法是个回调方法,在SelectEditPartTRacker#performOpen() 中调用的.
