Hi,
I think there is a misunderstanding.
I want to be able to have hierarchies inside each container node, but by defining the edges once for the overall graph. So, the graph would look almost like in the picture below, but without the shifting:
For example, I want to show classes grouped in packages, and show inheritance, too. Right now, I have to do it like this:
packages := { 'Glamour-Core' asPackage . 'Glamour-Presentations' asPackage }.
view := RTMondrian new.
view shape rectangle fillColor: Color yellow.
nodes := view nodes: packages forEach: [ :pack |
view nodes: pack definedClasses.
view edges source: pack definedClasses connectFrom: #superclass to: #yourself.
view layout tree ].
classesWithInheritanceBetweenPackages := (packages flatCollect: #definedClasses)
select: [ :each | each isClass and: [each package ~= each superclass package] ]
thenCollect: [ :each | each -> each superclass ].
view edges source: classesWithInheritanceBetweenPackages connectFrom: [ :x | x value ] to: [ :x | x key ].
view
This means that I explicitly have to pick the edges that I want to draw in the different contexts: once to draw only the local edges, and once to draw only the non-local edges. If layouts would be applied lazily, I could simply do this:
packages := { 'Glamour-Core' asPackage . 'Glamour-Presentations' asPackage }.
view := RTMondrian new.
view shape rectangle fillColor: Color yellow.
nodes := view nodes: packages forEach: [ :pack |
view nodes: pack definedClasses.
view layout tree ].
view edges source: (packages flatCollect: #definedClasses) connectFrom: [ :x | x superclass ] to: [ :x | x ].
view
As this is not possible now, I was thinking of still constructing the graph in the simplified form by defining edges once, but then we apply the layout later inside each container node, which is still cumbersome.
Cheers,
Doru

Using nodes that belongs to different parent nodes?
Well… I do not know how to do this.

Hi,
I expect to see a “tree" inside each top node.

Hi Doru,
Nesting is indeed a weak point of currently version of Roassal.
Future version of Roassal will ease this.
Try this script:
-=-=-=-=-=-=-=-=-=-=-=-=
view := RTMondrian new.
view shape rectangle fillColor: Color yellow.
nodes := view nodes: { { 1 . 2 } . { 11 . 12 } } forEach: [ :col |
view nodes: col ].
view edges source: { 1 . 11 } connectFrom: [ :x | x ] to: [ :x | x + 1 ].
view edges source: { 1 . 2 } connectFrom: [ :x | x ] to: [ :x | x + 10 ].
nodes do: [ :each |
RTNest new
layout: RTTreeLayout new;
centerOn: each elements: each nestedElements ].
view
-=-=-=-=-=-=-=-=-=-=-=-=
I am not completely sure to understand what the result should be. What do you expect?

Hi,
Actually, my script does not work because the nested nodes are shifted internally.
So, now I do not know any solution for my issue. Any ideas?
The issue is visible when we give the root elements a color:
view := RTMondrian new.
view shape rectangle fillColor: Color yellow.
nodes := view nodes: { { 1 . 2 } . { 11 . 12 } } forEach: [ :col |
view nodes: col ].
view edges source: { 1 . 11 } connectFrom: [ :x | x ] to: [ :x | x + 1 ].
view edges source: { 1 . 2 } connectFrom: [ :x | x ] to: [ :x | x + 10 ].
nodes do: [ :each |
RTNest new
layout: RTTreeLayout new;
on: each nest: each nestedElements ].

Hi,
I am trying to use Mondrian for a case in which I have nested elements and crosscutting edges. The issue is that I only found a cumbersome way to specify the layout.
Here is an example:
view := RTMondrian new.
view shape rectangle fillColor: Color transparent.
nodes := view nodes: { { 1 . 2 } . { 11 . 12 } } forEach: [ :col |
view nodes: col ].
view edges source: { 1 . 11 } connectFrom: [ :x | x ] to: [ :x | x + 1 ].
view edges source: { 1 . 2 } connectFrom: [ :x | x ] to: [ :x | x + 10 ].
nodes do: [ :each |
RTNest new
layout: RTTreeLayout new;
on: each nest: each nestedElements ].

With bold I have showed the code necessary for applying the layout. In previous versions of Roassal/Mondrian, layouts were applied lazily, after the graph was constructed. This allowed us to write something like this:
view := RTMondrian new.
view shape rectangle fillColor: Color transparent.
view nodes: { { 1 . 2 } . { 11 . 12 } } forEach: [ :col |
view nodes: col.
view layout tree ].
view edges source: { 1 . 11 } connectFrom: [ :x | x ] to: [ :x | x + 1 ].
view edges source: { 1 . 2 } connectFrom: [ :x | x ] to: [ :x | x + 10 ].
view
Did I miss something or is this the only way supported currently?
Cheers,
Doru
