For fun I put the following trace in

    Transcript show: '.'.

And in general this method is invoked three times instead of one :)

Before asking we read all the examples and I saw that selector: is used to communicate and update the code pane.

(UIManager default newAutoAcceptTextEntryFor: self
            get: #selector
            set: #selector:
            class: String
            getEnabled: #haveClassName
            help: 'Enter a selector' translated
            entryCompletion: entryCompletion)
                acceptOnCR: false;
                ghostText: 'Selector';
                withDropListButton;

I think this is only for the drop down list.

What I meant is that I could use set: and pass the selector to be invoked by the dropdown when the drop down is selected. 
And it will notify self with the selector: selector. So we could sepcify any selector (ie I can register to the drop box and say call me once you are set). 

In RubMethodEditingExample>>#selector:

it calls the update explicit
 self updateCodeWith:  (cls sourceCodeAt: selector)

and updateCodeWith: sets the text on the text model.

 

Now my problem (and may be there is not solution) is how can I connect from a pluggableListMorph to a RubScrollText
when the list does not generate announcement.
This is why I tried to pass via dependents or something like that.

I will try to generate announcements but this is a lot more work and I do not know if it will work.
