Eclipse插件：标记的自定义图标 [英] Eclipse plugin: Custom icon for a Marker

问题描述

我想为标记指定一个自定义图标。不幸的是，我选择的图标不显示。

这是plugin.xml文件（项目编号x）的相关部分：

 < extension 
 id =xmlProblem
 name =XML问题
 point =org。 eclipse.core.resources.markers> 
< super type =org.eclipse.core.resources.problemmarker/> 
< persistent 
 value =true> 
< / persistent> 
< / extension> 
 
< extension 
 point =org.eclipse.ui.ide.markerImageProviders> 
< imageprovider 
 markertype =x.xmlProblem
 icon =icons / marker.png
 id =xmlProblemImageProvider> 
< / imageprovider> 
< / extension>我也尝试指定一个类（实现 IMarkerImageProvider ）而不是一个图标，但该类的 getImagePath（）方法不会被调用。 
 
 
 
有关如何使自定义标记图标工作的任何想法？

 VonC的解决方案是非常正确的，除了您必须不指定 org.eclipse.core.resources.problemmarker 作为标记的超类型。只有当我使用 org.eclipse.core.resources.textmarker 作为 超类型

我们从未有过这样的API，因为它有一些不灵活性，使得它通常不是可消费的 - 早期写的是为我们使用的3个严重性的第一个标记视图，因此没有使用markerSupport，因为它不是API。
 
 
 
令人困惑的是，我们有一个内部扩展点（我们通常不会
）但删除它可能会打破某人的威胁

随着Vonc的指点，我终于设法使这个事情发挥作用。 
这是我的 plugin.xml 中的相关片段（假设插件名称为 abc ）
 < extension point =org.eclipse.core.resources.markers
 id =myMarker> 
< super type =org.eclipse.core.resources.textmarker/> 
< persistent value =true/> 
< / extension> 
 
< extension point =org.eclipse.ui.editors.annotationTypes> 
< type 
 super =org.eclipse.ui.workbench.texteditor.warning
 markerType =abcmyMarker
 name =abcmyAnnotation
 markerSeverity = 1/> 
< / extension> 
 
< extension point =org.eclipse.ui.editors.markerAnnotationSpecification> 
< specification 
 annotationType =abcmyAnnotation
 icon =icons / marker.png
 verticalRulerPreferenceKey =myMarkerIndicationInVerticalRuler
 verticalRulerPreferenceValue =true/> ; 
< / extension> 
  
 陷阱 
 
 
 
 
 
标记的超级类型必须设置为 org.eclipse.core.resources.textmarker 。任何其他值将阻止您使用自定义图标。
 
 
在代码中创建标记时，请确保其严重性与 markerSeverity 属性在 org.eclipse.ui.editors.annotationTypes 扩展点。  1 表示警告等。
 
 
确保您的build.properties文件（或构建）选项卡中指定了图标文件夹在插件编辑器上）
 
 
上面的声明只会指定一个自定义图标。如果要自定义其他属性（概览标尺的指示颜色等），请从这里。
 
 
 
I want to specify a custom icon for a marker. Sadly, the icon that I chose is not displayed.

Here's the relevant parts of the plugin.xml file (the project id "x"):
<extension
      id="xmlProblem"
      name="XML Problem"
      point="org.eclipse.core.resources.markers">
   <super type="org.eclipse.core.resources.problemmarker"/>
   <persistent
         value="true">
   </persistent>
</extension>

<extension
      point="org.eclipse.ui.ide.markerImageProviders">
   <imageprovider
         markertype="x.xmlProblem"
         icon="icons/marker.png"
         id="xmlProblemImageProvider">
   </imageprovider>
</extension>
I also tried specifying a class (implementing IMarkerImageProvider) instead of an icon, but that getImagePath() method of the class does not get called. 

Any thoughts on how to make custom marker icons work?

Desperately, yours.

Update

VonC's solution is pretty much correct, except that you must not specify org.eclipse.core.resources.problemmarker as a supertype of your marker. It worked only when I used org.eclipse.core.resources.textmarker as the only supertype.

We have never had the push to make this API because it has some inflexibility that made it generally not consumable - it was written early on to enable the first marker views for the 3 severities we use and as a result was not used by the markerSupport as it was not API.
  
  
It is confusing that we have an internal extension point (we don't generally do
  that) but removing it would likely break someone without warning.
[EDIT by Itay]

Following on Vonc's pointers, I eventually managed to make this thing work. 
Here are the relevant fragments from my plugin.xml (assuming the plugin name is a.b.c)
  <extension point="org.eclipse.core.resources.markers"   
        id="myMarker">
     <super type="org.eclipse.core.resources.textmarker"/>         
     <persistent value="true"/>
  </extension>

  <extension point="org.eclipse.ui.editors.annotationTypes">
     <type
        super="org.eclipse.ui.workbench.texteditor.warning"
        markerType="a.b.c.myMarker"
        name="a.b.c.myAnnotation"
        markerSeverity="1"/>
  </extension>

  <extension point="org.eclipse.ui.editors.markerAnnotationSpecification">
     <specification
        annotationType="a.b.c.myAnnotation"
        icon="icons/marker.png"
        verticalRulerPreferenceKey="myMarkerIndicationInVerticalRuler"
        verticalRulerPreferenceValue="true"/>
  </extension>
Pitfalls


The super type of the marker must be set to org.eclipse.core.resources.textmarker. Any other value will prevent your custom icon from being used.
When you create a marker in your code make sure its severity matches the severity value specified in the markerSeverity attribute at the org.eclipse.ui.editors.annotationTypes extension point. 1 means warning, etc.
Make sure the icons folder is specified in your build.properties file (or the "build" tab at the plugin editor)
The declaration above will only specify a custom icon. If you want to customize other attributes (color of indication at the overview ruler, etc.) follow the sample from here on which this solution is based.
