Zest Graph - 可编辑还是不可编辑？如何开始上课？

标签： java eclipse zest

我正在开发一个项目，我打算在JAVA中创建一个可以创建图形的类。详细说来，我想创建2个接口--VERTEX和EDGE，每个接口都有addVertex（），addEdge（），neighborVertex（），numOfNeighbors（）等方法，以及我的类（称之为Graph）将实现上述接口。

我现在是JAVA的真正新手，并且想知道如何继续使用ZEST？另外，如果我使用ZEST，图表是否可以编辑？

Lars Vogel的教程帮助了我，但我仍然无法让它工作。如何解决以下错误？

如果要使用Zest可视化图形，则必须将自己的图形对象转换为Zest图形，或者首先使用Zest对象。请查看Eclipse wiki和this tutorial中的一些示例。

Zest（专注于可视化）不能编辑图形，但基于SWT可以使图形交互（将监听器添加到节点等）。如果您想要图表编辑，请查看Graphiti或类似JUNG。
