java - 将帮助我开发 Eclipse 行编号(如插件)的线索

Question

我想为 Eclipse 开发一个小插件，如果有人能给我一些指导，我将非常感激。基本上所有需要知道的是当前行编号面板是如何实现的，所以我需要一些具有类似功能的自定义插件的源代码，或者在 Eclipse 源代码中的位置来查看当前行编号功能。

感谢您的帮助。

Answer 1

查找IVerticalRulerColumn。根据 javadoc:

A vertical ruler column is an element that can be added to a composite vertical ruler (org.eclipse.jface.text.source.CompositeRuler). A composite vertical ruler is a vertical ruler with dynamically changing appearance and behavior depending on its actual arrangement of ruler columns. A vertical ruler column supports a subset of the contract of a vertical ruler.

要查找的类: org.eclipse.ui.texteditor.AbstractDecolatedTextEditor 大多数编辑器都会扩展它。

查找方法: createLineNumberRulerColumn()
