[Glamour] default selection in ListPresentation

by Cyrille Delaunay

Hello, Is there a way to set a default selection to a list presentation? so that when I open the browser, the morphic list has already a value selected. I tried that: |tmpBrowser| tmpBrowser := GLMTabulator new. tmpBrowser row: #list. tmpBrowser transmit to: #list; andShow: [:a | a list display: [:input | input]; selection: #a; yourself ]. tmpBrowser openOn: #( b c d v a d f r). but the list still open with nothing selected

[ann] gtspotter: a moldable interface for spotting objects

by Tudor Girba

Hi, Alex Syrel, Andrei Chis and I are happy to announce a new addition to the Glamorous Toolkit: GTSpotter, a novel interface for spotting objects. GTSpotter has two goals: - Provide a uniform yet moldable interface that can work on any object, and - Handle searching through arbitrary levels of object nesting. We think this will have a significant impact on the development workflow in Pharo. Here is a couple of screenshots: [image: Inline image 2] [image: Inline image 1] [image: Inline image 3] A trailer is available here: https://www.youtube.com/watch?v=PhSmjR3NOlU A detailed description is available here: http://www.humane-assessment.com/blog/introducing-gtspotter It works already in Pharo 3.0 and can be played with by following the instructions from: http://gt.moosetechnology.org Please let us know what you think. Enjoy, The Glamorous Team

Theme aware-ish TRMorph

by Peter Uhnák

Hi, since I wanted to use DarkTheme I played around with TRMorph (since seeing giant white rectangle in dark theme is not very nice). What I have done is moved the background color setting to `surface clear:` (instead of the original aCanvas fillRectangle). And then if theme background luminance is dark (>0.5), I invert all the colors in the visualization. For dark theme the background is black, and not the theme background - at least to me it seems that black is much clearer. Is this something that could be incorporated? And the modified code: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "protocol: drawing" TRMorph>>drawOn: aCanvas "aCanvas is a FormCanvas" self checkSession. "aCanvas fillRectangle: bounds color: trachelCanvas color." trachelCanvas playAnimations. "The drawing has to be done when a change in the shapes occured or when there is an animation." surface drawDuring: [:cs | surface clear: trachelCanvas color. "We display the elements that are subject to the camera" cs pathTransform translateBy: (self extent / 2) asFloatPoint; scaleBy: trachelCanvas camera scale asFloat; translateBy: trachelCanvas camera position negated asFloatPoint. trachelCanvas shapes do: [ :trachelShape | trachelShape drawOn: cs. ]. "We display the elements that are _NOT_ subject to the camera" cs pathTransform loadIdentity scaleBy: 1.001. trachelCanvas fixedShapes do: [ :trachelShape | trachelShape drawOn: cs. ]. ]. self theme backgroundColor luminance < 0.5 ifTrue: [ surface drawDuring: [ :cs | cs paintMode restoreAfter: [ cs setPaint: Color white. cs paintMode difference. cs drawShape: (0 @ 0 extent: surface extent) ] ] ]. "aCanvas translucentImage: surface asForm at: self bounds origin." "asForm creates a new Form, which is likely to be expensive. This can be cached" aCanvas image: surface asForm at: self bounds origin sourceRect: (0 @ 0 extent: surface extent) rule: 34. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Finding in a roassal view

by Alexandre Bergel

Hi! I have worked on the actions available in Glamour during the last few days. I have just added a find icon (glasses icon): Clicking on it open a spotter to look for element in the view. Selecting it move the camera to focus on it. Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

showing a diff on #assert:equals:

by Andrei Chis

Hi, I updated GTDebugger to automatically show a diff in the debugger when an #assert:equals: fails. For example if you execute '(GTSUnitExampleFailingTest selector: #testMultiValuedStreaming) debug.' you get the debugger below. Also works when running tests from Nautilus/TestRunner. The context from where #assert:equals: was called is also automatically selected. [image: Inline image 1] Let me know if you run into any issues. Cheers, Andrei

broken Roassal2Spec Adapter

by Peter Uhnák

Hi, apparently we broke MorphicRoassalAdapter when cleaning Spec, I attached a fix. However my question is - does anybody (except us) actually use the Roassal2Spec package? Because otherwise we could clean it a bit. For example I'm not sure of the use case of script:/lastEvent:. Peter

Editing methods in the inspector

by Alexandre Bergel

Hi! If I inspect a compile method, I have a tab showing the source code. But I cannot modify the source code of it (well, it does not compile). Is there a way to edit compile method within the GTInspector? Maybe using Ring?

Stack visualizations

by Hernán Morales Durand

Dear Roassal users and developers, I'm using Roassal in Pharo 4 and want to stack visualizations, something like: | stack1 stack2 | stack1 := RTStackBarPlot new. stack1 add: #(1 2 3 4). stack1 add: #(4 3 2 1). stack1 add: #(5 3 2 0). stack1 build. stack2 := RTStackBarPlot new. stack2 add: #(2 2 3 1). stack2 add: #(4 3 2 2). stack2 add: #(6 1 2 0). stack2 build. ^ (stack1 , stack2) view or stack1 append: stack2 is this currently possible? Cheers Hernán

Matrix sunburst: increasing the separation between arcs

by Offray Vladimir Luna Cárdenas

Hi, Pair programming with Milton at Smalltalks 2015, we (well mostly he) came with what I call a "matrix sunburst" that shows a sunburst diagram using a matrix instead of a tree as data source (the clever hack of Milton was to convert the data in the matrix to a tree with only one child on any branch after the first one!). The inspiration was taken from [1] and the idea was from a friend who want to use this kind of matrix alike sunburst to compare public medicine information. [1] http://www.theguardian.com/world/interactive/2012/may/08/gay-rights-united-… With this I can create thinks like this: But to get a more readable visualization, I would like to make two things: a. Increase the empty space between arcs, not like the current radial strategy, but more like the graphic at [1]. For this we thought in adding a RTEdge with the same color as the background. How can I calculate the position of every RTEdge at the final of each arch in the sunburst? b. I would like to keep each ring of the same size instead of making them narrower as the become more away of the center. It this possible? c. Finally I have created RTSunburstBuilder>>exploreMatrix: aMatrix coloredWith: aColorPalette in my own image, because I think that is the best place it can be to be reused in my own visualizations. Is this a good practice? Can I share this code back with the Roassal project? How? (hopefully I will not need to learn git and its gratituous complexity). Cheers, Offray
