eclipse插件：如何以编程方式选择文本？ [英] eclipse plugin: How to programmatically select text in editor?

问题描述

我想以编程方式跳转到文本编辑器中的位置并突出显示代码。

I want to programmatically jump to a position in the text editor and highlight code.

推荐答案

我无法获取安德鲁的答案在Eclipse 3.7中工作。编译器发出这个错误：

I wasn't able to get Andrew's answer to work in Eclipse 3.7. The compiler gave this error:

The method getSourceViewer() from the type AbstractTextEditor is not visible.

但是，我能够使用 selectAndReveal（）方法：

However, I was able to get it to work with the selectAndReveal() method:

IFile myfile = ...
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
ITextEditor editor = (ITextEditor) IDE.openEditor(page, myfile);
editor.selectAndReveal(offset, length);
