I do not like "el1 draggable" because I want to keep ROElement as small as
possible.
I do not see the point.
You can package extension in separate package and use class extension so ?
Now what I see is verbose code.
This is why you have to write:
el1 @ RODraggable
or:
el1 addInteraction: RODraggable
or:
RODraggable initializeElement: el1
I would not describe the last one.
I favor el1 draggable because it is concise and says what is does.
All these 3 formulation are the same.
I favor @ because it is shorter. Shall I remove it? What is the general opinion on this?
Personally I think that @Dragable will just break effort of type inferencer and this is
sad.
Same for +
el1 +
ROBox blue.
what is the advantage over
el1 color: #blue ?
or
> el1 := ROElement new
> el1 box green ; draggable
by doing "el1 + ROBox" I am sure that the class ROElement does not know at all
about boxes and colors. to me the +
and @ looks complex and a bit ugly.
Then I do not understand why we can give an extent: before saying that this is a box?
Currently you can. But following the discussion I had last week with Doru, it seems wiser
to have the shape decide the extent and not the element itself.
Cheers,
Alexandre

| view el1 el2 edge line |
view := ROView new.
el1 := ROElement new.
el1 draggable ; box blue.
el1 extent: 50@50.
el2 := ROElement new.
el2 draggable; box green.
el2 extent: 50@50.
looks better to me.
Hi!
I know this has been on the wished list of many of you. The following script produces:

el1 := ROElement new.

el1 extent: 50@50.
el1 + ROBox blue.

el2 @RODraggable.
el2 extent: 50@50.
el2 + ROBox green.
el1 translateTo: 0 @ 100.
edge := ROEdge from: el1 to: el2.
line := ROLine new.
line add: ROArrow new offset: 0.1.
line add: ROArrow new offset: 0.5.
edge + line.
view add: el1; add: el2; add: edge.
view open

I will remove ROArrowedLine very soon then
