Ruler Action via menus extension point [message #638510]

I'm trying to add commands to the left-hand ruler of an AbstractTextEditor. How do I do that via org.eclipse.ui.menus extension point? (all the examples I've found show how to add commands to various other locations)

Here's an example:

+ <extension point="org.eclipse.ui.menus">
+ <menuContribution
+ locationURI=" popup:#AbstractTextEditorRulerContext?after=QuickDiff.Toggle ">
+ <command
+ commandId="org.eclipse.team.cvs.ui.showAnnotation"
+ style="push">
+ <visibleWhen
+ checkEnabled="false">
+ <with variable="activeEditorInput">
+ <test
+ property="org.eclipse.team.internal.ccvs.ui.isManaged"
+ value="true">
+ </test>
+ </with>
+ </visibleWhen>
+ </command>
+ </menuContribution>
+ </extension>

That worked like a charm, thanks!

Now can you tell me how to get at the IVerticalRulerInfo? Specifically I'm looking for the line-number where the ruler was clicked when selecting the action.

I can get the line number of the text selected in the editor by getting the editor from the context variables, but I don't see how to get the ruler or its line of last activity...
final AbstractTextEditor editor=(AbstractTextEditor)event.getApplicationContext.getVa riable( "activeEditor");
editor.getSelectionProvider();

OK, found it:

private Integer getRulerLine(ExecutionEvent event)
{
if(event.getApplicationContext() instanceof EvaluationContext)
{
final EvaluationContext context=(EvaluationContext)event.getApplicationContext();
final IEditorPart editor=(IEditorPart)context.getVariable("activeEditor");
final IVerticalRulerInfo verticalRulerInfo=(IVerticalRulerInfo)editor.getAdapter(IVer ticalRulerInfo.class);
if(verticalRulerInfo!=null)
{
return verticalRulerInfo.getLineOfLastMouseButtonActivity();
}
}
return null;
}
