Hi,
I'm new to Squeak ST and am trying to create some views using MVC.
I found a sample and I've tried to run the following in a workspace and
get and error see below test/error...
Do I need to initialize ScheduledControllers and if so how?
Thanks, Theo
PS I'm not new to Smalltalk, I've been using Dolphin ST Pro for a few years.
====== test code ==============
"from: http://wiki.squeak.org/squeak/478 "
| form pen view topView |
form := Form extent: 300 at 300 depth: Display depth.
form fillColor: Color green.
pen := Pen newOnForm: form.
pen defaultNib: 4.
1 to: 50 do: [:i | pen go: i*4. pen turn: 89].
view := FormView new.
view model: form.
view borderWidth: 2.
topView := ColorSystemView new.
topView model: form. "to set the correct window size"
topView addSubView: view.
topView controller open.
=========== end of test code ==============
It fails on the last line of the above,
the error is generated by: StandardSystemController >> open
statement: ScheduledControllers scheduleAvtive: self
error: MessageNotUnderstood: UndefinedObject .. scheduleActive:
