Attaching KeyListener (or some such) to AbstractTextEditor [message #280074]

Hello,

I need a way to intercept each key press (or change in the unsaved text of
the editor) in a subclass of AbstractTextEditor.

Any pointers as to how I can do that?

Context: I have an editor that edits a string buffer, and I do not want to
save in the editor in order to update the string buffer - I want to keep
the buffer in synch with the unsaved buffer in the editor.

Thanks
-i

You mean you want to keep the buffer up to date while typing?

If you type the underlying document / buffer gets updated automatically.

See org.eclipse.swt.custom.StyledText.modifyContent

If you register a document listener you will be called when the document
changes.

See
org.eclipse.jface.text.presentation.PresentationReconciler$I nternalListener.
documentChanged
for an example.
