Hi All,

I have created a Read Write Editor, which is a sub class of
org.eclipse.ui.texteditor.AbstractDecoratedTextEditor. I want to show line
nos in this editor. Can you just let me know, is it possible to add line
no to this editor? If yes, how to add line no to this editor?

Thanks,
M.S.Thiraviyakumar

I believe all you need to do is turn on the "Show line numbers" option
on the "General->Editors->Text Editors" preference page.

In below I have pasted the code which is being used. I want to show Line
no & Line no ruler in this RWEditor. Can you please let me know the
way/logic to do so?
public class RWEditor extends AbstractDecoratedTextEditor {
public RWEditor () {
super();
internal_init();
}

protected void internal_init() {
configureInsertMode(SMART_INSERT, false);
SimpleDocumentProvider docProvider = new SimpleDocumentProvider();
docProvider.setModifiable(true);
setDocumentProvider(docProvider);
}
}

Per default line numbers aren't shown. You have to set the
AbstractDecoratedTextEditorPreferenceConstants.EDITOR_LINE_N UMBER_RULER
to true.
