I have some basic intro questions on Morphic. I'm digging through the
source code, and reading what I can find on the web, but it is quite a
lot to take in.
1. Messages
There seem to be at least 2 ways to handle messages with Morphic. The
subclassing way, overriding methods such as *handlesMouseDown* and so
on, and *on:send:to:* way. What are the differences between the two,
and why would I prefer one over the other?
2. MorphicModel
The MorphicModel class appears to be for morphs that implement the view
side of MVC. However, I find the source rather confusing. What on
earth is a *slotSelector*, for instance? And a method like
*compileAccessForSlot* just leaves me baffled. What is this class for,
and are there any simple examples of its use?
3. PasteUpMorph
I know that the screen background is a PasteUpMorph, but I see them
mentioned elsewhere from time to time. What exactly is a PasteUpMorph?
Would I ever want to use one? Is there a simple example?
Thanks in advance for your help.
P.S. I just figure out how to make balloon text work. This stuff is cool!
