Eclipse插件：高亮显示代码行（调试时使用文本标记）

Question

Please do not confuse this with 'selecting code' like selecting code with a mouse.

When my debug device hits a break point I want to highlight the specific line of code. I am using the CDT Plugin.

I already got the lineNumber and all I want to do now is to tell

editor.highlightLine(lineNumber);

to get something like this:

I already tried this:

      marker = resource.createMarker(IMarker.TEXT);
      marker.setAttribute(IMarker.LINE_NUMBER, 10);
      marker.setAttribute(IMarker.CHAR_START, 0);
      marker.setAttribute(IMarker.CHAR_END, 10);

but it didn't work.

Since there are already predefined annotations provided by Eclipse and/or the CDT Plugin I'd like to reuse them. But how to access and use them inside sourcecode?

Answer 1

You can create your own marker using an extension point "org.eclipse.core.resources.markers" and adding super attribute of type "org.eclipse.core.resources.textmarker" . After setting up your marker, you still need to describe its look and feel by adding the annotation extension point "org.eclipse.ui.editors.annotationTypes"

I am not exactly sure of your intentions but this link might help http://www.ibm.com/developerworks/opensource/tutorials/os-eclipse-plugin-guide/section3.html

Marker is the thing on your ruler. You need to look at the editor background painting. Take a look at InstructionPointerManager.java
