Hi,
I have a tree layout scene and I am trying to add on top other edges that do not affect
the layout and that should have a centered attach point. However, the edges are still
being drawn from bottom to top, like the rest of the edges from the tree layout.
I think this is a bug. What do you think?
Here is the example:
view := RTMondrian new.
view shape label.
view nodes: (1 to: 10).
edges := view edges connectFrom: [ :x | x//2 ].
view layout tree userDefinedEdges: edges.
view shape arrowedLine color: Color red; centeredAttachPoint.
view edges source: {3->2 . 9->7} connectFrom: #key to: #value.

Hi,
the problem is that LayoutBuilder (not the layout itself) changes the attach points in
RTLayoutBuilder>>tree .
I think there is some deeper issue with attach points, because RTTreeLayout will override
attach points to RTVertialAttachPoint by default. So it's applied twice, but
differently. I also think that changing (by default!) attach points in Layouting
algorithms is violation of responsibility, but I thought in relation to Mondrian having
some good-enough defaults probably makes sense.
In any case, a solution can be to do the opposite of what you've done --- specify what
edges should NOT be used in the layout, e.g.:
view := RTMondrian new.
view shape label.
view nodes: (1 to: 10).
view edges connectFrom: [ :x | x//2 ].
view layout tree.
view shape arrowedLine color: Color red; centeredAttachPoint.
view edges notUseInLayout source: {3->2 . 9->7} connectFrom: #key to: #value.

Hi Peter and Doru,
This is a nice spot. I fixed the problem of double attach point assignment, which was
causing the behavior spotted by Doru. Try version 1505 of Roassal2 please.
Cheers,
Alexandre
