Beginner's questions

Hi all,
I tried to build my first user interface with Pharo. I ran into some problems, I have a bunch of questions. These are certainly quite simple to answer for any veteran... If any of you could so kind as to not only answer them but also to tell me where I sould have looked for the answer, this would be awesome. I used Pharo By Example as well as the pharocasts and the occasional google search to find info. My code can be found at : http://ss3.gemstone.com/ss/MakeMeASandwich.html - I build the UI by hand, this is tiresome. Is there a GUI UI builder ? I found Morphic designer (https://www.hpi.uni-potsdam.de/hirschfeld/trac/SqueakCommunityProjects/wiki/designer) and UIBuilder (http://forum.world.st/CLFramework-UIBuilder-td1302485.html) but it is unclear if any or both are the Right Way (tm) of doing things with Pharo. - As you can see if you do RecipeEditor new open, there is a lot of wasted space. Lists do not expand to take all the vertical space they could. What is the workaround for that ? - I have a list created by : nodeList := ListModel new list: SortedCollection new. put on screen by : builder newListFor: self list: #nodeList selected: #selectedNodeIndex changeSelected: #selectNodeAtIndex: help: 'Liste des étapes'. and I use : nodeList list at: (nodeList selectionIndex) on the press of a button to get the selected element of a list. I would like this list to allow for multiple selection, and I would like to get the list of selected elements. I tried to fool around with some methods having "multiple" in their name, but to no avail. - The text fields require the user to accept (command-S) the modification before I can get the content with getText. Is there a good way to get the non accepted text ? I tried to to an UI with tk before, and compared to that it has been a breeze with Smalltalk, the way one can write the highest level call and then use the debugger to create methods and variables on the fly is very enjoyable. Thank you in advance, Cheers, Edouard. |

Shall I use Paro 2.0 ? (Currently using 1.4). I am not sure I tried the right methods. What should I do from a clean brand new image to install it ? ========================================================= Gofer new url: 'http://ss3.gemstone.com/ss/Spec'; package: 'ConfigurationOfSpec'; load. (Smalltalk at: #ConfigurationOfSpec) perform: #loadFull ========================================================= It works in 1.4 and in 2.0. Then you could have a look at the category named Spec-Examples :) If you want I have a really out dated doc, but I do not think it useful anymore (but I will rewrite it soon).

Thank you, I was able to install Spec on 1.4. I have seen the example
with the multiple selection list. I will try to solve my problems by using Spec, and I sure will bother you if I run into problems ;) Cheers, Edouard.

Take this as a draft, but it may help a bit :)

Have you evaluated a more mature Smalltalk for UI building? There is VisualWorks, Dolphin, etc.
Believe it or not, Smalltalk has possibly the oldest UI programming environment... and still no cross-ST open source UI builder, isn't amazing? Cheers, Hernán 2012/5/13 Edouard Klein <[hidden email]> Hi all, |

Thank you, I have read it, and I believe I understood the concepts. I
will try it soon and get back to you afterwards.
