Listen for click on editor tab [message #272968]

I have an editor which needs to do various things when it gains the focus
(refresh enablement of actions etc). The editor extends EditorPart and
contains a single Canvas.

The problem is that switching between editor instances by clicking on the
tabs at the top of the editor pane doesn't give focus to the Canvas - you
have to click down on the canvas each time to cause a change of focus.

How can I listen for changes in selection of editor (either by clicks on
the tabs or any other means), so that I can automatically pass the focus
to the canvas?

Thanks very much

The proper way to do this is to override "setFocus()".

While this is not what you want to be doing, you can listen for the part
activation event -- available from WorkbenchPage.

cheers,

May be setFocus() for your WorkbenchPart?
