how to create a custom IMarker with a custom icon? [message #1067043]

I understand that the org.eclipse.core.resources.markers extension point will allow me to create a custom marker, which I can then instantiate as follows:

IMarker marker = resource.createMarker("com.my.custom.marker");
marker.setAttribute("myAttribute", "x");
marker.setAttribute(IMarker.SEVERITY, IMarker.SEVERITY_ERROR);
marker.setAttribute(IMarker.LOCATION, "1");
marker.setAttribute(IMarker.LINE_NUMBER, 1);
marker.setAttribute(IMarker.DONE, true);

That works great, with the exception that the only "custom" markers I know how to create would be either custom "problem", "bookmark", "task" or "text" markers, which would then inherit the corresponding icons.

My objective is to create markers with custom icons.

Is there a simple way to do accomplish this or would it be a major hack probably not worth the trouble?

You should be able to make customizations using the IMarker interface . Ideally there are much more marker types than what you describe above . Maybe one of them will fit the type for which you need a marker . See here for all the categories http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fcore%2Fresources%2FIMarker.html

Regarding your question of whether it is possible to associate a different icon to a custom icon I think it may be possible(not 100% sure) . See the section ``Marker representation in the platform`` in the first link given below . However the exact way to do you will have to figure it out yourself Very Happy

Note:
There is also blog which i am unable to post because i have less than 5 messages ( some forum restrcition) If you really need it let me know .

You will need to create a custom view that will be applied to your marker type. Example:

<extension
point="org.eclipse.ui.views">
<view
class="com.eclipse_tips.markers.MyCustomMarkersView"
icon="icons/sample.gif"
id="com.eclipse-tips.markers.customMarker"
name="My Custom Markers">
</view>
</extension>

As shown above, the "icon" is your custom icon image and "id" is your custom marker id.

You may find this blogpost helpful: (since I can't submit links due to low posts, google "prakash creating a custom marker view" and it should be the first one.

Check out custom view type here: http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Fguide%2Fworkbench_basicext_views.htm[/url]

Another useful link about annotation types here: http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fextension-points%2Forg_eclipse_ui_editors_annotationTypes.html

This may not be the only way to do it, but I added a custom icon to my marker by using the markerAnnotationSpecification extension point:

<extension
         id="my.marker"
         name="Testing Marker"
         point="org.eclipse.core.resources.markers">
         <super type="org.eclipse.core.resources.textmarker"/>
         <persistent value="true"/>
   </extension>
   <extension
   		 id="my.annotationType"
   		 name="Testing Marker Annotation"
         point="org.eclipse.ui.editors.annotationTypes">
      <type
            markerType="my.marker"
            name="my.annotationType">
      </type>
   </extension>
	<extension
         point="org.eclipse.ui.editors.markerAnnotationSpecification"
         id="my.annotationSpec">
      <specification
            annotationType="my.annotationType"
            includeOnPreferencePage="true"
            overviewRulerPreferenceKey="clruler"
            label="Testing"
            icon="lib/mycustomicon.ico"
			overviewRulerPreferenceValue="true"
			highlightPreferenceKey="highlight.background"
			highlightPreferenceValue="true"
			colorPreferenceKey="clcolor"
			colorPreferenceValue="0,255,0"
			textPreferenceKey="cltext"
			textPreferenceValue="true"
			presentationLayer="0"
			verticalRulerPreferenceKey="clvertical"
			verticalRulerPreferenceValue="true"
			textStylePreferenceKey="clstyle"
			textStylePreferenceValue="BOX">
      </specification>
   </extension>

Hope this helps.
