Re: [Pharo-users] Data Week: A week long workshop on data visualization using Pharo and Roassal

by Sebastian Heidbrink

Hi Offray, I started a software night here in town and I was also thinking about presenting the GTToolkit and Roassal to the crowd. You mentioned something that made made me wonder. You said that even non programmers liked the language. How did you approach them? Did you give them prepared interface implementations to Twitter and also a predefined GTToolkit browser implementation? Or did they just use the inspector? What does one need to use Twitter as a base for a demo? A developer account I guess? How stable is Pharo of it comes to the usage by non Smalltalkers and non developers? I thought one might spent most of the time with explaining what which tool is what not to use "just now!" Is there any library or framework available on smalltalkhub.com that you could recommend as a base for such presentation/workshop? Thank you!

[Ann] DragPanels: Floating palette windows with drag-and-drop in Morphic

by Stephan Eggermont

Morphic offers everything needed to create highly interactive applications in Pharo. It is however, difficult to find out how to actually create those applications. Morphic tutorials provide a starting point, and are not very good at showing how the different features interact and are supposed to be used together. Morph has lots of methods, and some of them are not in the method category where you might expect them. The result is that most Morphs in Pharo do not use much of what Morphic has to offer. Wouldn't it be great if there would be some sample code, showing how Morphic can be used to great effect? Well, here is some code that takes a first step towards that goal. DragPanels shows how to create a floating palette, filled with wells that support dragging a property towards a target. It shows how to combine drag-and drop with click: and context menu actions, and show to give UI feedback when over a well and when holding the mouse down over an element that reacts to click:. You can see the code in action here: https://vimeo.com/131889858 The color panel shows some colors. If you don't set the allowDropBlock, it will work with any morph that responds to #color: (like the world). By clicking on the plus, you can add more colors to the panel. The panel has a context menu to restore the default values. ColorPanel withSevenPaleColors allowDropBlock: [ :source :target | target class = CardMorph ]; openInHand The people panel shows avatars belonging to an email addres. By default it uses gravatar for them, and caches the images. PeoplePanel new defaultValues: #('stephan(a)stack.nl' 'serge.stinckwich(a)gmail.com' 'nicolas.anquetil(a)inria.fr' 'thierry.goubier(a)gmail.com' 'stephane.ducasse(a)inria.fr' 'marcus.denker(a)inria.fr'); allowDropBlock: [ :source :target | target class = CardMorph ]; openInHand When dropping, the dragSource sends #color: resp. #email: to the target by default. By setting the dropSelector of the DragWell this can be overridden. You can try the code by do-ing Gofer new smalltalkhubUser: 'StephanEggermont' project: 'Dragpanels' package: 'DragPanels'; load. It is used in (a work in progress) Gofer new smalltalkhubUser: 'StephanEggermont' project: 'Documentation' package: 'CardsMorphic'; load. Stephan p.s. On the wishlist are - add more color palettes - add a dark theme, refactoring the colors - add a small close cross in the title bar of the palette - define the dropSelector in the panel, not the well - support different sized wells, refactoring the sizes - make the mouseOver rectangle color content dependent - add pharo contributors as an avatar source - add a configuration
