Eclipse - 悬停在标记上时的自定义文本 [英] Eclipse - custom text when hovering over a marker

问题描述

我在Eclipse插件上工作，目前我正试图让Eclipse（Luna）在鼠标悬停时显示自定义文本。我知道我可以通过指定标记参数来实现这一点，但是我需要动态改变文本，例如：

我已经尝试过这些方法，没有成功：

< 1）使用自定义 SourceViewerConfiguration 定制 TextEditor ：

  public class MyEditor extends TextEditor {
 $ b $ public MyEditor（）{
 setSourceViewerConfiguration（new SourceViewerConfiguration（）{
 @Override 
 public IAnnotationHover getAnnotationHover（ISourceViewer sourceViewer）{
 return new IAnnotationHover（）{
 @Override 
 public String getHoverInfo（ISourceViewer sv，int ln）{
 returnHel我的世界！; 
} 
}; 
} 
}）; 
} 
} 
  

和plugin.xml是这样的：

 < extension 
 point =org.eclipse.ui.editors> 
< editor 
 id =test
 name =MyEditor
 extensions =c
 class =foo.bar.editors.MyEditor> ; 
< / editor> 
< / extension> 
  

我的方法 getHoverInfo 永远不会被调用。相反，每次打开任何* .c文件并将鼠标悬停在标记上时，都会调用 DefaultAnnotationHover 中的 getHoverInfo 方法。我通过Eclipse-> Preferences-> General-> Editors检查了可用的编辑器，并且 MyEditor 在那里。

2）动态添加自定义注释悬停。我在这里找到了 信息，这是可能的。所以每次打开一个* .c文件，我都有这样的代码：

  IPartListener2 partListener2 = new IPartListener2（）{ （$（））.equals（（（EditorReference）partRef）.getDescriptor（）。
 @Override 
 public void partOpened（IWorkbenchPartReference partRef）{
 if（org.eclipse.cdt.ui.editor.CEditor.equals .getId（）））{
 CEditor currentCFileEditor =（（CEditor）（（EditorReference）partRef）.getEditor（false））; 
 currentCFileEditor.getViewer（）。setAnnotationHover（new IAnnotationHover（）{
 @Override 
 public String getHoverInfo（ISourceViewer sourceViewer，int lineNumber）{
 returnHello world; 
} 
}）; 
} 
} 
  

但是，我没有成功 - 我的 getHoverInfo 根本不被调用。

任何想法我做错了什么？

解决方案

谁有类似的问题 - 我发现了一个哈克解决方案。我创建了自己的类 MyAwesomeHover ：

$ b

  public class MyAwesomeHover implements IAnnotationHover {
 @Override 
 public String getHoverInfo（ISourceViewer sw，int ln）{
 returnHey hoo
} 
} 
  MyAweseomeHover 作为显示的  

> AnnotationHover 。

  Field hm = SourceViewer.class.getDeclaredField（fVerticalRulerHoveringController）; 
 hm.setAccessible（true）; 
 AnnotationBarHoverManager ma =（AnnotationBarHoverManager）hm.get（sourceViewer）; 
 Field ah = AnnotationBarHoverManager.class.getDeclaredField（fAnnotationHover）; 
 ah.setAccessible（true）; 
 ah.set（ma，MyAwesomeHover（））; 
  

I working on an Eclipse plugin and currently I am trying to make Eclipse (Luna) to show customized text when hovering over a marker. I know that I could achieve this by specifying the marker arguments, but I need to change the text dynamically, e.g:

I have already tried these approaches without success:

1) Having a custom TextEditor with custom SourceViewerConfiguration:

public class MyEditor extends TextEditor {

    public MyEditor() {
        setSourceViewerConfiguration(new SourceViewerConfiguration() {
            @Override
            public IAnnotationHover getAnnotationHover(ISourceViewer sourceViewer) {
                return new IAnnotationHover() {
                    @Override
                    public String getHoverInfo(ISourceViewer sv, int ln) {
                        return "Hello world!";
                    }
                };
            }
        });
    }
}

and the plugin.xml like this:

<extension
        point="org.eclipse.ui.editors">
    <editor
            id="test"
            name="MyEditor"
            extensions="c"
            class="foo.bar.editors.MyEditor">
    </editor>
</extension>

My method getHoverInfo is never called. Instead, the method getHoverInfo from the DefaultAnnotationHover is being called any time I open any *.c file and hover over the marker. I checked the available editors via the Eclipse->Preferences->General->Editors and the MyEditor is there.

2) Adding the custom annotation hover dynamically. I found here information that it is possible. So every time I open a "*.c" file, I have this code:

IPartListener2 partListener2 = new IPartListener2() {
    @Override
    public void partOpened(IWorkbenchPartReference partRef) {
            if ("org.eclipse.cdt.ui.editor.CEditor".equals(((EditorReference) partRef).getDescriptor().getId())) {
                CEditor currentCFileEditor = ((CEditor)((EditorReference) partRef).getEditor(false));
                currentCFileEditor.getViewer().setAnnotationHover(new IAnnotationHover() {
                    @Override
                    public String getHoverInfo(ISourceViewer sourceViewer, int lineNumber) {
                        return "Hello world";
                    }
                });
            }
        }

But again, I was not successful - my getHoverInfo is not called at all.

Any idea what I am doing wrong?

解决方案

For those who have a similar problem - I have found a "hacky" solution. I have created my own class MyAwesomeHover:

public class MyAwesomeHover implements IAnnotationHover {
    @Override
    public String getHoverInfo(ISourceViewer sw, int ln) {
        return "Hey hoo"
    }   
}

And then I use the reflection to set MyAweseomeHover as the displayed AnnotationHover.

    Field hm= SourceViewer.class.getDeclaredField("fVerticalRulerHoveringController");
    hm.setAccessible(true);
    AnnotationBarHoverManager ma= (AnnotationBarHoverManager) hm.get(sourceViewer);
    Field ah= AnnotationBarHoverManager.class.getDeclaredField("fAnnotationHover");
    ah.setAccessible(true);
    ah.set(ma, MyAwesomeHover());
