Morphic basics with a little Watch (Horloge in french).

Add the class:

StringMorph subclass: #Horloge
 instanceVariableNames: ''
 classVariableNames: ''
 poolDictionaries: ''
 category: 'Sandbox'

One method called periodically thanks to stepping mechanism of Morphic:

 self contents: Time now printString.

Then evaluate in a Workspace:

Stop the watch:

Horloge allInstances last stopStepping

Start it again:

Horloge allInstances last startStepping

Finally close it:

Horloge allInstances last delete
