Re: [Pharo-project] Issue 4036 in pharo: Please update Help> Announcements tutorial

To remove the subscription you can evaluate: World announcer initialize. Maybe the tutorial should add (pesudo code): MyStuff>>initialize World announcer                on: WindowOpened                send: #showOnTranscript                to: self SystemAnnouncer on:#classremove send:#release: to: self. MyStuff>>release: anAnn World announcer unsuscribe: self. MyStuff>>showOnTranscript Transcript show: 'A new window was opened';cr I can update the tutorial if people agrees on the pseudo code. To open a transcript evaluate: TranscriptMorph openWindow (decoupled Transcript from Morphic, so directly ask the view to open itself) Fernando On Sun, Apr 17, 2011 at 12:41 PM, <pharo@googlecode.com> wrote:

New issue 4036 by marcus.d...@gmail.com: Please update Help> Announcements tutorial http://code.google.com/p/pharo/issues/detail?id=4036

1. Not understanding how announcements work, I tried the tutorial information found under World menu > Help> Help Browser > Announcements framework

2. Under Tutorial - Step 3, there is this line:

 "Transcript open."  That crashes, because apparently Transcript no longer understands 'open'.  How do you open a Transcript from a workspace under 1.3?

3.  I created a category 'Sandbox', and a class 'MyStuff'.  I put the code from Tutorial -Step 3 into a method called anno1

Object subclass: #MyStuff        instanceVariableNames: ''        classVariableNames: ''        poolDictionaries: ''        category: 'Sandbox'!

!MyStuff methodsFor: 'as yet unclassified' stamp: 'DougEdmunds 4/14/2011 16:27'! anno1        | announcer |        World announcer                on: WindowOpened                send: #value                to: [ Transcript show: 'A new window was opened';cr].! !

I ran "MyStuff new anno1." in a workspace. Now every time I open a window, the Transcript shows.  "A new window was opened."

4.  I removed the MyStuff class.  But every time I open a window, the Transcript still shows "A new window was opened."

I return to the Announcements Tutorial, and there is NO EXPLANATION how to get rid of this 'announcement' or whatever I should call the line that appears in the Transcript.

6. So, please whoever wrote the Tutorial, update it.

7. And the more immediate question: how do I stop automatically printing  'A new window was opened'  in the Transcript every time I open a window?
