Hello Squeakers,
It is cool that we have this forum for asking these kinds of questions.
-- TL;DR -- I learned I probably shouldn't subclass a singleton even though it
seemed so easy; I wonder instead how to design my controller properly in an
MVC paradigm; should I learn about Factory method
Hi everyone,
I have a bunch of objects (all instances of the same class) which each hold a
Date. There is another singleton-style class which holds a Dictionary to keep
track of those objects, where the key is the Date and the value is the object.
How bad is it that I am keeping the date once

Hi,
I'm in 4.2. When I switch the desktop to a gradient fill, I get a dark
gray-light gray ("graydient" ha).
On the same world menu, I have the option to "change first color" and "change
second color." These
bring up color requesters, but whichever colors I pick don't seem to change the

Hi,
Fresh 4.2 image. Opened Browser. Made a new category. Made a new class.
Tried to change the class comment but can't. Can't, can't, can't. Can you?
For me, it always goes back to "THIS CLASS HAS NO COMMENT!" What is going on?
Thanks,

Hi,
I am wondering about the "Holder" morph. If I drag-select over it, it shrinks
in size. But not if I drag-select from the right-bottom of it.
To reproduce: drag a Holder morph onto the desktop. Hold down "shift" and
left-click drag from below-and-left of the Holder. Drag part way into t

Hi,
I was trying to package up some old code of mine using Monticello so I could
migrate to a new image (and also maybe take advantage of MC's revisioning, too).
When MC got to the "Snapshotting methods..." process, it was choking on a class
method that didn't exist. It was trying to get the c

I'm digging into some code I haven't touched in at least a year. I was

The error that appears to be happening is when I attempt to put something in

Does anyone have, or know of, existing code to perform the rather

Hi,
I know the rules for naming accessor and setter methods. But what do I do
when the accessor method needs a parameter? I'll try to provide an
example.
A vendor sells an item called #apple. If I want to get the vendor's price
for that #apple, I use a method such as the following:
