[Glamour] default selection in ListPresentation
by Cyrille Delaunay 24 Mar '18

24 Mar '18

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 23 Sep '17

23 Sep '17

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 24 Feb '16

24 Feb '16

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 04 Dec '15

04 Dec '15

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 04 Dec '15

04 Dec '15

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 03 Dec '15

03 Dec '15

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 01 Dec '15

01 Dec '15

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 30 Nov '15

30 Nov '15

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 27 Nov '15

27 Nov '15

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
