Roassal: Opacity
by Dennis Schenk 14 Sep '12

14 Sep '12

Hi, Is it possible in Roassal to draw nodes in a layout with different opacities? A simple example would be: drawing a tree with nodes less opaque the deeper their nesting level is. Cheers, Dennis

Thank you. Will try that first Stephan

glamour perf
by Usman Bhatti 14 Sep '12

14 Sep '12

Hello all, I sat with Benjamin today to have a look at Glamour performance when displaying large text files. For reminder, when displaying text in glamour, the time to display text increases exponentially with the size of the text being displayed. Two observations: 1/ Whereas, with the following script the execution time remains equivalent to that of morphs MessageTally spyOn: [ (*GLMPluggableTextMorph* on: [ (StandardFileStream fileNamed: 'testfile-glam-3500.txt') contents ] text: #value accept: nil) openInWindow extent: (1273.0(a)738.0) ] the execution of this script is four times longer: | browser text| browser := *GLMTabulator* new. browser column: #text. browser transmit to: #text; andShow: [ :a | a text title: 'Text with selection'; display: [(StandardFileStream fileNamed: 'testfile-glam-3500.txt') contents]]. MessageTally spyOn: [browser openOn: 2]. 2/ A bit of digging (using time profiler) shows that the garbage collector is taking 75% of the execution time. [image: Inline image 1] Doru, will you have an idea what makes garbage collector execute and take extra seconds when the text is displayed in a glamour browser instead of individual glmaour widget? The moose image with the scripts can be found here if you want to have a look. http://dl.dropbox.com/u/11804892/glamour-perf-tests.zip thanx in advance, Usman

PetitParser // FLFactorialExample
by H. Hirzel 11 Sep '12

11 Sep '12

Hello PetitParser comes with a Factorial Language example. The comment of the class FLFactorialExample states "I implement the example given in "factorial.txt". The code can be edited directly in the Smalltalk code browser and is automatically parsed, transformed and eventually compiled down to Smalltalk bytecodes." Where do I find the description of this language, i.e. the file 'factorial.txt'? Regards Hannes

Issue 834 in moose-technology: Roassal layouts do not properly take into account userDefinedEdges
by moose-technology＠googlecode.com 10 Sep '12

10 Sep '12

Status: New Owner: ---- CC: alexandr...(a)gmail.com Labels: Type-Defect Priority-Medium Component-Roassal Milestone-4.7 New issue 834 by tu...(a)tudorgirba.com: Roassal layouts do not properly take into account userDefinedEdges http://code.google.com/p/moose-technology/issues/detail?id=834 To reproduce see the example below: | edges | view nodes: #(1 2 3). edges := view edgesFrom: [:each | each - 1]. view shape line color: Color red. view edges: #(3) from: [:each | each - 2] to: #yourself. view treeLayout userDefinedEdges: edges If the user defined edges would be taken into account, the tree would appear on one line (1->2->3). Instead it appears laid out as 1->2, 1->3 .

It shows ROCircleLayout2 and ROCircleLayout3 as missing from your 289 mcz, which implies they are is in my image, except I have previously deleted those two classes from my image prior to saving through Monticello. Do they show up to you?

Hi, How do I programmatically export a PNG of the entire visualization from Roassal? I tried to use the ROView>>bitmap, but it returns a cropped image. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
