quick question on Glamour
by Esteban Lorenzano 11 May '15

11 May '15

I have a browser with a tree and a text after it… I want my browser to show with an initial value. This does not seems to work: presenter tree; children: [ :node | node children ]; selection: { someNode }. nor: presenter tree; children: [ :node | node children ]; selectionPath: { someNode }. I’m lost :) Esteban

Roassal bezier line error
by Peter Uhnák 09 May '15

09 May '15

Hi, it seems that last control point of a bezier line is off. Here is a comparative view of RTBezierLine (black line) and bezier line done with SVG (red line). Notice how the bottom half is flatlined and doesn't match up. And the code (based on RTRoassalExample>>exampleBezierCurve): ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | v e1 e2 l s p1 p2 path svg| v := RTView new. e1 := (RTEllipse new size: 15; color: (Color blue alpha: 0.4)) element. e2 := (RTEllipse new size: 15; color: (Color blue alpha: 0.4)) element. e2 translateBy: -150 @ 150. p1 := RTBox element. p2 := RTBox element. p1 translateTo: (e2 position x + e1 position x / 2) @ e1 position y. p2 translateTo: (e2 position x + e1 position x / 2) @ e2 position y. v add: p1. v add: p2. s := RTBezierLine new. s color: Color black. s controllingElements: (Array with: p1 with: p2). l := s edgeFrom: e1 to: e2. v add: e1. v add: e2. v add: l. path := 'M -150 150 Q -75 150 -75 75 Q -75 0 0 0'. svg := RTSVGPath new borderColor: Color red; path: path; element. v add: svg. ^ v ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Peter

by Yuriy Tymchuk 08 May '15

08 May '15

Hi, in all versions of Roassal I could as an element in which view it is. But it looks like Roassal-Woden doesn’t have this API. Is there a different philosophy? Uko

by Alexandre Bergel 07 May '15

07 May '15

Dear Colleagues and Friends, We are happy to announce we will organize a CampSmalltalk about the Roassal visualization engine, on _Sunday 12 July_. As far as we have seen, the interests are multiple. Here is a list of topics we will happy to work on: - Improving Grapher, our charting library - Fixing bugs, addressing recently uncovered issues (e.g., composite shapes) - HTML/JavaScript export Some participants have indicated a great interest in: - Port of Roassal on VisualWorks - Using Roassal on Gemstone If you wish to participate, get in touch with us. Since we will probably have a sponsoring of the event, it would be nice to know how many will attend to ease the logistic and the pizza ordering :-) Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

06 May '15

Hi all! I want to build a dynamic graph on a composer.. Is that possible? It throws up an error on 'b add:ds', ie. when I want to add the dataset. It throws a 'MessageNotUnderstood' error. Can't I pass the Dynamic Grapher a RTStackedDataSet? Thanks! buildDynamicGraph:anObjectArray onComposer:aComposer | b ds | b := RTDynamicGrapher new. b view: aComposer view. ds := RTStackedDataSet new. ds points: anObjectArray. ds y: #second. ds barShape width: 30. ds histogramWithBarTitle: #first rotation: 0. b add: ds. b axisX noLabel; noTick. b build. ^ b

Hi! If you have an image with Roassal open, give a try: v := RTView new. v when: TRMouseClick do: [ :event | v clean ]. v when: TRMouseMove do: [ :event | e := (RTBox new color: (Color red alpha: 0.2); size: 20 atRandom + 5) element. e translateTo: event positionFromCamera. v add: e. v addAnimation: (RTAccelerationMove to: event positionFromCamera + ((150 atRandom - 75) @ (150 atRandom - 75)) during: 5 on: e) ]. v :-) Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
