[Pharo-dev] Spec delete method

Hi ben

I would like to unsubscribe announcement when the window is closed.
Is there a hook for that in Spec?

Re: [Pharo-dev] Spec delete method

I do not think it's a UI framework concern to handle model behaviour (like registration to announcement)

I guess what Stef means is that he would like to know if there is a way specify custom behavior when a window closes, and then use this for his purpose of unregistering from some announcer.

Cheers,

Doru

Ok :)

Then there is a hook in Morph for that I think :)

(and an announcement in Spec when a widget is built)

You can add this to the initialize method of your widget, and in the close method unregister all announcers

self whenWindowChanged: [:w | w whenClosedDo: [ self close ] ].

I notice that more frequently in your replies. To not judge people. We do not need it.

We are all good programmers. I need to know if there is a hook not that you

explain me that my design is bad, because it is not ;) I think that I know what are layer, MVP, MVC and little friends are.

This is not my model behavior. I want my ui not to get notification

from my model anymore. So to me this is the responsibility of the UI to unregister itself

and I do not see who else could do it.

I have again the same problem that my Spec UI instance is not garbage collected and

I only use weak announcements and I need to understand why.

Ok I just tell you because I know that you are not like that :)

I loaded my code in the fresh and latest 30 and invoking the GC this time

removed the UI instance. So I prefer that.

Now my logging frameworks can get a streamLogger that displays information by default in the

transcript and in the UILogger.

I'm getting where I wanted.
