Hi,
We are currently making some visualizations of application with Usman. They rely on method
invocations. In that case, it is better to know which method invokes which other one. We
put arrow on our graph, but the only available arrow we found are 'UML like
inheritance' arrow with big triangle. Would it be possible to have other type of arrow
that are more discrete, but nevertheless indicates the sense? (If possible put acute and
not obtuse angle between the two branches of the arrow, it is more easier to see when they
are lot of links).
More over, would it be possible to have hook on the lines to transform them as broken
lines. Indeed, when you have m1 linked to m2 and m2 linked to m1, there is superposition
of the two links so not easy to read. It would be great if we can manually break the lines
to see the two of them.
I put some examples of arrow below.
Thanks a lot in advance.

Hi!
As you have seen, Roassal offers way to define arrows. Here is a short example:
-=-=-=-=-=-=-=-=-=-=-=-=
| v s e1 e2 l |
v := ROView new.
s := ROEllipse new size: 15.
e1 := s element.
e2 := s element.
e1 @ RODraggable.
e2 @ RODraggable.
e2 translateBy: 50 @ 80.
l := (ROLine new add: (ROArrow new size: 10)) elementFrom: e1 to: e2.
v add: e1; add: e2; add: l.
v open
-=-=-=-=-=-=-=-=-=-=-=-=
You can always create a new array by subclassing ROArrow or ROLineDecoration.

Hi,
Thanks Alexandre.
With your explanation, I modified the drawOn: for: fromPoint: toPoint: line: method of
ROAbstractRow. I have almost what I want. I removed the line closing the triangle of the
head, I reduced the right and left extremity of the head. But I would like that there is
no space between the head and the body of the arrow. Can you please indicated me where to
look for since I modified the toPointWithOffSet value with any modification on the image?
Perhaps is it in another method that the body of the arrow is defined.
I think that when it will be done, it can interest others (We shouldn't be the only
one using arrow ;))
Thanks in advance.

look for since I modified the toPointWithOffSet value with any modification on the image?
Perhaps is it in another method that the body of the arrow is defined.
I think that when it will be done, it can interest others (We shouldn't be the only
one using arrow ;))
Thanks in advance.

https://www.iam.unibe.ch/mailman/listinfo/moose-dev Hi!
As you have seen, Roassal offers way to define arrows. Here is a short example:
-=-=-=-=-=-=-=-=-=-=-=-=
| v s e1 e2 l |
v := ROView new.
s := ROEllipse new size: 15.
e1 := s element.
e2 := s element.
e1 @ RODraggable.
e2 @ RODraggable.
e2 translateBy: 50 @ 80.
l := (ROLine new add: (ROArrow new size: 10)) elementFrom: e1 to: e2.
v add: e1; add: e2; add: l.
v open

You can always create a new array by subclassing ROArrow or ROLineDecoration.

are lot of links).

It works for me.

Usman,
Since with the jet lag, you won't have any answer from Alexandre before a
couple of hour, I resend his email on Arrow in Roassal. It's sure that it
could be good if good if we can have the same arrow in Roassal 2.
Anne
PS: if you change the size value, it changes the size of the head of the
arrow

You just need to update Roassal

Hi,
Thanks Alexandre.
With your explanation, I modified the drawOn: for: fromPoint: toPoint:
line: method of ROAbstractRow. I have almost what I want. I removed the
line closing the triangle of the head, I reduced the right and left
extremity of the head. But I would like that there is no space between the
head and the body of the arrow. Can you please indicated me where to look
for since I modified the toPointWithOffSet value with any modification on
the image? Perhaps is it in another method that the body of the arrow is
defined.
I think that when it will be done, it can interest others (We shouldn't be
the only one using arrow ;))
