[Newbies] a simple Morph

I have some difficulties to create a morph, which shows me simply all
elements of an array inside that morph.
my morph has an instance var called myArray.
now the morph should simply show the contents of myArray.
and here my confusion start. I don't want to reprogram
PluggableListMorph. But I don't get this thing to use myArray. I guess
PluggableListMorph want's to have a model. Or?
So I should the MVC stuff, or?
I did some morphic tutorials, but none of these showed me, how to build
a more complex morph. There are rectangles, drag and drop and so on.
But there is nothing like: here is a collection, now show me all
elements of that collection inside a morph (as a list).
In my understanding, I would build a classic MVC-triple. But as i
understood Morphic, there is no need for classic MVC anymore. So I am
My realisation so far:
BorderedMorph subclass: #MenschMorph
| c m|
self extent: 50 at 50.
self position: 50 at 50.
self color: Color white.
self liste: #('name' 'alter' 'huhu').
c := 1.
m := TextMorph new openInWorld.
m position: self position + (1 at c*10).
self addMorph: m.
Now i would write some manipulation stuff for 'liste'. I would delete
all the TextMorphs and simply redraw them, but with my manipulated list
as new 'input'.
And that feels damn wrong to me. How to proceed?
My goal should be a Morph, which shows me simply the contens of a list.
The Morph should update itself, when i manipulate the list. Classic MVC
for me. Am I right?
