Create a plugin for extending editors [message #658361]

Hello,

I have been trying there last days to extend the default editor (java, xml, all of them) functionality,

what I want to do is add a big ruler with text on the side of every editor.

example: a default editor page looks like this:

|-----------|
|source     |
|code       |
|           |
|-----------|

but i want it to be like this

|------|----|
|source|    |
|code  |line|
|      |text|
|------|----|

also i can't use a view because the text in my ruler corresponds to a certain line and has to scroll along with the source code.

I have tried to do this by implementing IEditorActionDelegate since I don't want a new editor, but to add functionality, but I could not find any solutions.

Eclipses text editors are based on AbstractTextEditor and
org.eclipse.ui.texteditor.AbstractDecoratedTextEditor (which adds the
ruler on the left side and the annotation bar on the right side).

Since each editor has its own createPartControl(*) called and then
creates whatever controls it wants to, I don't see how you can add a new
control to the right of already existing editors (although you can
certainly subclass and change your own). Well, you could in theory hack
another child into the part parent composite, but only by digging
through internals and I doubt it would work the way you want.
