Stepping through diameter of CircleMorph

Hi i have a new sub class for CircleMorph which has step method.

step
self extent: self extent +1.
(self extent )>(300@300) ifTrue: [self stopStepping]

This changes center of circle when i start stepping,Is there a way i can do this without changing center for CircleMorph.

Re: Stepping through diameter of CircleMorph

can you file out your class and send us the code?

You might change the bounds instead of the extent:

step
self bounds: ((self bounds) expandBy: 1).
(self extent) > (200@200) ifTrue: [ self stopStepping ]

I updated my Stackoverflow answer too ;)
