[Moose-dev] Re: Dynamically adding nodes to Roassal

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 elements stack t classes | 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. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Alexandre On Sep 30, 2013, at 4:21 AM, roberto.minelli(a)usi.ch wrote: 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- behavior of the ROTreeMapLayout is not clear to me. 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. 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. Alejandro's advice I am writing something like: elements. understand why all sizes are messed up. changed (i.e., sizes, parents, resize strategy). Am I correct? is it the correct behavior? map? Am I doing everything correct till now? -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
