How to : Add mouse hover info to marker and notify location in ruler [message #487470]

Hi,

I am developing a plug-in using eclipse-3.4.2 on WinXP.
The plug-in uses native editor but has its own views.
I have a created a custom marker (with special icon and so on) which works fine.

Now I want its (marker's) location to be shown in the right-side ruler of the java editor in some explicitly mentioned color. Like eclipse shows location of a line with
an error with a red mark /
a warning with a yellow mark.

I also want to provide mouse-hover informations like:
A mouse-hover on the location-indicator on ruler should display line number.
A mouse-hover on the marker icon of a particular line should display a tool-tip-text kind of yellow box with some imp information.

I was told by Paul in irc that I should use AbstractDecoratedTextEditor.
Then realized (after going through help) I'll need to use the extension point org.eclipse.ui.workbench.texteditor.rulerColumns
I didn't find any article / example of usage of that ex point despite of plenty of web-searches.

The question is, how to achieve all the above without having a custom editor and in connection with a marker?

Thanks.

Have found answer to one of my two questions.
Adding tool-tip kind-of yellow box to the mouse hover on marker was easy.
I had to do this :
marker.setAttribute(IMarker.MESSGE, "Hello...");

Now it'd be really appreciated if someone could explain how to go about adding a notation to the right side ruler which would display line number on mouse hover for the above said marker.

Thanks.

You can't show a different message. See
'org.eclipse.ui.editors.markerAnnotationSpecification' extension point
on how to let your marker appear in the ruler.

Yes. I realized that and have successfully made use of the extension point org.eclipse.ui.editors.markerAnnotationSpecification and it works fine.
i.e. It displays the intended message on mouse hover on both marker as well as annotation.
This thread can be closed now if it should be.

Thanks.
