Cool Alex! I will take a look at your solution now!
Cheers,

Hi Roberto,
First of all, I really would like to thank you for your email. This kind of emails are
really important for improving Roassal.
I have solved your problem. Check this video: https://vimeo.com/75820243
Even though the solution is quite ad-hoc, I think you can play with it. Consider the
following examples:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
"View"
| view elements stack t running |
view := ROView new.
view @ RODraggable.
"Stack, useful to have a menu"
stack := ROViewStack new.
stack addView: view.
t := 0.
running := nil.
stack addMenu: '+1' callBack: [ :evt |
t := t + 1.
view elementsDo: #remove.
elements := (ROElement forCollection: (1 to: t)) collect: [:e | e + (ROBorder gray size:
200) + ROBox ].
view addAll: elements.
running := view elements first.
view elements allButFirst do: [ :el |
view add: (ROEdge lineFrom: running to: el).
running := el.
].
" ROHorizontalLineLayout on: view elements.
" (ROTreeMapLayout withWeightBlock: [ :e | e model ]) applyOn: elements.
].
stack open.

"View"

view := ROView new.
view @ RODraggable.
"We prepare the data"
classes := ROShape withAllSubclasses asSortedCollection: [ :c1 :c2 | c1 name < c2 name
].
t := 0.
"Stack, useful to have a menu"
stack := ROViewStack new.
stack addView: view.
stack addMenu: '+1' callBack: [ :evt |
"Increment the amount of classes found in the visualization"
t := t + 1.
"We clean the view"
view elementsDo: #remove.
elements := (ROElement forCollection: (classes copyFrom: 1 to: t)) collect: [:e | e +
(ROBorder gray size: 200) + ROBox @ ROPopup ].
view addAll: elements.
view elements allButFirst do: [ :el |
view addAll: (ROEdge buildEdgesFromElements: elements from: #superclass to:
#yourself).
].
" ROTreeLayout on: view elementsNotEdge edges: view elementsAsEdge.
" (ROTreeMapLayout withWeightBlock: [ :e | e model numberOfLinesOfCode]) applyOn:
elements.
view signalUpdate.
].
stack open.

Hi,
I am playing around with Roassal (in particular, a tree map) and I have a question: Is
there a way to dynamically adding nodes? I mean, once the view is generated to update the
#nodes by adding a new node (and associations as well, i.e., edges) and have the
visualization re-
At the moment I managed to have something *almost* working, but the behavior of the
ROTreeMapLayout is not clear to me.
Using the ROMondrianViewBuilder I can specify the size of the Tree map, but then I am not
able to dynamically add nodes. Well, at least I did not manage to do that. So I moved to
pure Roassal, as suggested by Alejandro.
Here's how my actual code looks like: http://ws.stfx.eu/CFM522Z9X3ES
I am a beginner with Roassal, so I spend some time to figure out how to draw the tree map
in this way. I did not really quite understand why I have to add the ROBox new size: 200
to the ROElement, but I'll figure it out.
The thing is when I try to add the new node. Following, again, Alejandro's advice I
am writing something like:
"I add a new node, re-layout the view, and signalUpdate"
rawView add: ((ROElement on: 10) + (ROBox new size: 200)).
(ROTreeMapLayout withWeightBlock: [ :e | e model ]) applyOn: rawView elements.
rawView signalUpdate .
The result is quite strange, the view is indeed updated but I cannot understand why all
sizes are messed up.
I think that once I apply the layout, the "elements" array is actually changed
(i.e., sizes, parents, resize strategy). Am I correct? is it the correct behavior?
My questions, in short are: How can I fix the overall size of the tree map? Am I doing
everything correct till now?
Thanks again for your help,
Roby
