如何在标尺上添加标记？ [英] How to add a marker on the ruler?

问题描述

我试图在Eclipse中的垂直标尺上添加一个标记/图标。我使用以下代码

I am trying to add a marker/icon on the vertical ruler in Eclipse. I used the following code for it

     IEditorPart editor = PlatformUI.getWorkbench()
        .getActiveWorkbenchWindow().getActivePage().getActiveEditor();
     IFileEditorInput input = (IFileEditorInput)editor.getEditorInput() ;
     IFile file = input.getFile();
     IProject activeProject = file.getProject();
     IResource res = (IResource) activeProject;

     IMarker m;
     try {
            m = res.createMarker("com.examples.problem");
            m.setAttribute(IMarker.LOCATION, offset);
            m.setAttribute(IMarker.MESSAGE, "Hello");
            m.setAttribute(IMarker.LINE_NUMBER, offset);
      } catch (CoreException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      }

其中offset是我想要标记的行号。
这段代码是标记，但不在标尺上，而是在控制台和错误日志旁边的问题视图中。任何想法如何解决它？另外，如果有任何其他方式在标尺上添加一个切换/图标/标记，请咨询。

Where offset is the line number where I want the marker. This piece of code the a marker but not on the ruler, but on the Problems view next to Console and Error log. Any idea how I can fix it? Also if there is any other way of adding a toggle/icon/marker on the ruler, please advice.

推荐答案

markerAnnotationSpecification扩展点。这用于自动定义标记和编辑器注释之间的映射，并具有指定的格式。

You should use markerAnnotationSpecification extension point. This is used to define a mapping between markers and editor annotations automatically, with specified formatting.
