Hi, It's me again..
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. 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 On Sep 20, 2013, at 11:24 AM, [email protected] wrote: > Hi, > > I was playing around with Roassal (in particular, a tree map) and I have a > question: Is there a way to dynamically adding nodes?
