Re: [Pharo-dev] Stability of 3.0

by kilon

I dont have such problem. The problem I had was code completion having several errors while it tried to autocomplete and once I froze pharo because I changed a live object while the morph was displaying , that method was somewhat recycled (HelpBrowser class) so that may have been normal. But no problem with red boxes from what I can see, I am on 30402. -- View this message in context: http://forum.world.st/Stability-of-3-0-tp4709185p4709358.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Also I forgot to tell you that the new book "Deep into Pharo" has a chapter for Roassal and another for Mondrian.

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

by roberto.minelli＠usi.ch

Thanks Alejandro, Yes I went through the examples and I understood the difference between the examples using the builder (which are easier) and with pure Roassal, which are..let's say.. less user friendly.. I am trying, in pure Roassal, to do a tree map and add another node to the ROView then calling signalUpdate. No luck 'till now..

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

by Alejandro Infante

Well, If you started with the Easel then you must have seen the examples. Well at first you see two boxes with examples inside (one on the top and the other below (If you dont see the second one just drag the view). The first one has a label at the top-left corner that says ROMondrianExample, and this were done using the ROMondrianViewBuilder API, and you can see that you interact mainly with the "view" variable. The second box is called ROExample and then you interact mainly with the "rawView" variable which is pure Roassal. The difference between them is that the ROMondrianViewBuilder is a nice and friendly API, but doing really complex stuff it's not possible. So we go one level below to pure Roassal. Here you have the Collection class hierarchy in Roassal: |rawView| rawView := ROView new. Collection withAllSubclasses do: [ :c | | el | el := ROBorder elementOn: c. el @ ROPopup. rawView add: el ]. "Draw edges" rawView addAll: (ROEdge buildEdgesFromElements: rawView elements from: [ :cls | cls superclass ] to: #yourself using: ROLine new). ROTreeLayout on: rawView elementsNotEdge edges: rawView elementsAsEdge. rawView open. I recommend you to see the ROExamples and if there is something that you don't know just ask to the mailing list. You may like to see the ROExamples>>interactions>>addingOnClick example. 2013/9/20 roberto.minelli(a)usi.ch <roberto.minelli(a)usi.ch> > Thanks Alejandro, I will try what you propose! > > What do you mean by > > Another thing bothering me is that you mentioned the method #nodes, > thats from the ROMondrianViewBuilder, which I think is not that friendly > with dynamic stuff. > > How would you construct a view without using the ROMondrianViewBuilder?
