Hi Leo,
Sorry to reply so late.
Your script does exactly what it is supposed to do. Maybe part of the shape semantic is
not clear.
Consider this part of the script:
e on: TRMouseClick do: [ :event |
e shape color: Color random. e update. els atRandom update. view signalUpdate ]
You click on an element e, which means you change the shape of the element. You update the
element itself, it therefore changes its color. But with "els atRandom update” you
also update another element. Since the shape is shared by all the elements, the behavior
is indeed correct.
A shape is shared with all the objects. What is not shared are Trachel shapes.
You have the following relations:
shape := RTBox new size: 10.
e1 := shape elementOn: 'hello'.
e2 := shape elementOn: 'world'.
self assert: e1 shape == e2 shape.
self assert: e1 shape ~~ e1 trachelShape.
self assert: (e1 shape isKindOf: RTBox).
self assert: (e1 trachelShape isKindOf: TRBoxShape).
self assert: e1 trachelShape ~~ e2 trachelShape.
Let me know if something is not clear. I have written this in the class comment of
RTShape.
Cheers,
Alexandre

Hi,
I'm not sure it is but I think I have found a bug where elements share the same
instance of a shape.
Here an example:
view := RTView new.
els := (RTBox new size: 20) elementsOn: (1 to: 10).
view addAll: els.
els do: [ :e |
e on: TRMouseClick do: [ :event |
e shape color: Color random. e update. els atRandom update. view signalUpdate ]
].
RTHorizontalLineLayout on: els.
view open
It should only change the color of one element but it doesn't.
So I don't know if it is wanted or not.
