is Trait a behavior?

by Martin Dias

Hi all I have some methods receiving either a Class or a Trait instance as parameter, so I usually call variables with names like 'aClassOrTrait'. Searching for a more synthetic name, I wonder if 'aBehavior' would be fine. But IMO these examples show contradictions: - Trait *is* a behavior: TBehaviorCategorization users ---> an IdentitySet(Class Trait) TPureBehavior users ---> an IdentitySet(TraitBehavior Behavior) (actually this makes me think 'aPureBehavior' is another alternative for my variables) - Trait is *not* a behavior: TBehaviorCategorization isBehavior ---> false TClassAndTraitDescription users ---> an IdentitySet(ClassDescription TraitDescription) (I both are behaviors, why not call it TBehaviorDescription?) Thanks in advance for your help. MartÃn

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?

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.

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…) 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 Ã©tapes'. 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.
