Re: [Pharo-users] Custom layout in Spec

by webwarrior

I implemented SpecTableLayout, which uses TableLayout policy. Wasn't that hard, beacuse actual layouting *is* done in Morphic. Interface of SpecTableLayout is somewhat similar to SpecLayout. All table layout options are supported (see http://wiki.squeak.org/squeak/2340) One thing that is not part of TableLayout and was added by me is spacer - invisible element that is either fixed size or flexible (aka spring). Most Spec widgets were designed to occupy all available space, and in order to change that they may be wrapped into single-element table layout. This is done using #add:wrapped: or #add:withSpec:wrapped with last argument being block (a similar to #newRow: and #newColumn:). For example: Now I wonder how do I transfer these changes from Monticello to GitHub in order to make pull request? -- View this message in context: http://forum.world.st/Custom-layout-in-Spec-tp4762142p4762995.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Pharo3.0 + Swap Ctrl and Alt keys

by Thushar G R

Can anyone confirm this 1) Open fresh Pharo3 image in Windows. 2) Go to *TextEditor>> buildTextEditorShortcutsOn:* 3) Change the last line from *(aBuilder shortcut: #cursorEnd)* * category: #TextEditor* * default: Character end ctrl win | Character end ctrl unix | Character end command mac* * do: [ :target :morph :event | target cursorEnd: event ]* To *(aBuilder shortcut: #cursorEnd)* * category: #TextEditor* * default: Character end ctrl win | Character end ctrl unix | Character end command mac* * do: [ :target :morph :event |* * self halt.* * target cursorEnd: event ]* 4) Take a workspace and do "*Ctrl + d*" on "*1 inspect.*" What happens for me is that it goes into the halt that we placed in step 3). And what i dont understand is why do it match the Keystroke "*Ctrl+d*" with "*Ctrl + END*". If you go back the stack you will find that's exactly whats happening. Let me know if i made some mistakes here.. Thanks for helping, G R Thushar *G R Thushar* *Team Leader(Technology),* *Signos Software Solutions Pvt.

Pharo3.0 + Swap Ctrl and Alt keys

by Thushar G R

Hi all, In Pharo 2.0 i find that "Ctrl+d" would do the doIt in workspace. In Pharo3.0 for doIt, i need to do "Alt+d". 1) Is this change intentional? 2) if so am i advised to practice all the shortcuts using Alt keys instead of Ctrl key for pahro 3? 3) Any way to bring back the Ctrl/Alt swap settings (I have asked this before in stackoverflow) 4) Any one knows a hack or workaround for this? Actually i was trying to figure out point 4) but no luck till now. I changed it in keymappings builders in AbstractNautilusUI and similar places but it simply dont work. Any help is appreciated and TIA. G R Thushar

One direction is to use more structured ways of editingâ¦ but one needs to take care that in the past (end of the 80ties) all the tries of structured editors where not really successful. But having an AST like representation instead of text would not preclude to have an editor interface that provided both the flexibility of a text editor with the knowledge and power of a real object representation of code belowâ¦ very interesting direction.

Hi Matthew, Is this an ongoing project? If yes, I would be interested in learning more about your effort and see if there are no synergies with the work on GToolkit.

Roassal forms+edges

by rosariosm

Hi, I'm trying to do a visualization that shows a group of twitter users connected to each other. It shows the images from the users but when i add the edges, the images dissapear. Here's the code: view := RTView new. e1 := RTElement on: user1. e2 := RTElement on: user2. elements := OrderedCollection newFrom: {e1. e2}. elements do: [ :e | | label shape form edge | label := RTLabel new text: e1 model name. form := Form fromFileNamed: 'aFilename'. shape := RTBitmap new form: form. e + (RTVerticalCompositeShape new shape1: shape; shape2: label) ]. line := RTArrow new color: Color red. view add: (line edgeFrom: e1 to: e2 ). view addAll: elements. view open. View without edges <http://forum.world.st/file/n4762851/withoutEdges.png> View with edges <http://forum.world.st/file/n4762851/withEdges.png> Anyone know how to fix this (show both images and edges)??

Re: [Pharo-users] Gradualtalk

by Johan Fabry

Hi Bob, AFAIK itâs not required for the subclasses to use TTyped as well. If that does not work in your case do tell us, that means thereâs a bug somewhere. Gradualtalk, as is, is a research prototype and not ready for production at all. We are doing experiments with GT, but it would take a considerable effort to have it ready for daily use in âreal lifeâ situations. Sadly we do not have such resources at our disposal. :-( On Jun 12, 2014, at 12:50 PM, Bob Williams <rwilliams19(a)cox.net> wrote: > Johan > > Thank you for pointing me to the VM download on the Pharo site, that worked > after I changed Pharo.exe to Gradualtalk.exe.
