Hi!
I know this has been on the wished list of many of you. The following script produces:
-=-=-=-=-=-=-=-=-=-=-=-= | view el1 el2 edge line | view := ROView new. el1 := ROElement new. el1 @RODraggable. el1 extent: 50@50. el1 + ROBox blue.
el2 := ROElement new. 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

Thanks Alex. But I think arrowed line was a good tool to show relationship between two entities without specifying the position of arrow. So, it will be good if you can keep it.

Hi Usman,
The ArrowedLine is a particular case that does not deserve its own class. Composition is much better here because we can construct the shapes the way we want (and we can control each .
The arrow at the end of the line can be added as a convenience method. Perhaps something like this: edge + ROLine + ROArrow.
This does not yet work because some convenience methods are missing, but other than that it should work out of the box. As soon as I get some rights, I can even commit :).
Cheers, Doru

The information about where the arrow should be placed in the ROArrow rather than in the ROLine. Like this you could just compose the two without the Line knowing anything about the Arrow.
As you propose it also makes sense, but the problem is that adding the Arrow decorator happens through a different mechanism (addBeginning:) than the regular one (addShape:).

+ adds a shape decorator. @ adds an interaction.
I quite like this part. Maybe draggable could be a nice addition, but I would prefer, in general, to keep the API to a minimum and add convenience methods as they are needed in practice. +RODraggable is quite simple once you get used with the idiom.
el1 + ROBox blue.

Indeed, blue is a convenience conceptual hack :). I guess the idea is that because Roassal offers a DSL that also works on classes (not just instances) through default constructors, it was just convenient to not have to add parentheses. But, it is a bit of a hack.

Currently, the Element defines the extent and the shape is drawn around this extent. I do not like this either. I think the shape should hold the extent for the shape and the Element bounds should be computed based on what the shapes are saying.

Instead of + and @ you can use addShape: and addInteraction:, respectively.
I do not like "el1 draggable" because I want to keep ROElement as small as possible. This is why you have to write: el1 @ RODraggable or: el1 addInteraction: RODraggable or: RODraggable initializeElement: el1

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.

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.

Your argument does not hold. because we are not in Java and you could package nicely ROBox in a separate package and have some nice class extensions.
What I do not like with + is that + is functional and now you use it to modify conceptually the receiver. + is not equal to add:

I agree with you. I could use class extension. However I am kind of reluctant to use class extension in this case. Many many methods will have to be defined on ROElement as class extension. Maybe the tools we use are not good to manage class extension enough.
