Someone completely new to Pharo and SmallTalk likely is wasting the time of those who are routine practitioners. A separate list for newcomers might be a good idea. Regards : Hubert Wagner

Re: [Pharo-users] Loading and using Designer

It will probably not work. We are working slowly on a new UIBuilder using spec but benjamin had to restart following lectures so we make less progress on this site.

Re: [Pharo-users] GUI Painter

by Johan Fabry

Hi Hubert, no, you are not missing a significant point. There is nothing inherent in Smalltalk that prevents having a modern GUI painter. Just as there is nothing inherent that prevents it from having many other modern development tools. It's "just" that there has not been a strong and consistent effort in those directions, which unfortunately has lead Smalltalk to lag behind in those respects. Regarding the GUI stuff, Benjamin has been doing some good work on Spec, which should include a GUI painter at some point. So I guess I can say that we are trying â¦ On Sep 27, 2012, at 2:47 PM, Hubert Wagner <hdmw(a)sukiya.fr> wrote: > Hello Stephane : > Thank you for the welcome message. > >> Second: our goal is to create an ecosystem around pharo...if you have...needs for business or anything else just let us know. > > > I'm a Mac OSX user and newcomer to SmallTalk and to Pharo.

simulating has and belongs to many (HABTM)

by sergio_101

i just want to make sure that i am thinking about this the seaside/smalltalk way.. i would like to build a 'has and belongs to many' relation where i can drill down on my data from either side. say i have a movie, and a theater. a movie can be shown in many theaters, and a theater can show many movies. i would want to be able to ask a theater what movies it's showing, or a movie which theaters it is showing in. my initial thought would be to create a 'showing' model, where it would have a movie and a theater attached.. then i could query showing for either movie or theater.. or, i could have a theaters Collection on movies and a movies Collection on on theaters, and contain that information in only two models.. any suggestions? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

ScriptLoader prepareForProduction for one. Open you app on the system and make the window unclosable, undestroyable (Morphic halos). Save the image like that. Alternatively, check the doc of StartupLoader and the samples on the class side. Phil 2012/9/27 Peter K.H.

I have Pharo 1.4. Should I try this with 2.0? once you loaded ConfigurationOfDesigner check the instance-side methods, ConfigurationOfDesigner browse there should be plenty of versions :), then you can do (ConfigurationOfDesigner project version: 'FoundVersionString') load best cami

GUI Painter

by Hubert Wagner

Hello Stephane : Thank you for the welcome message. > Second: our goal is to create an ecosystem around pharo...if you have...needs for business or anything else just let us know. I'm a Mac OSX user and newcomer to SmallTalk and to Pharo. I have an uncomfortable feeling my question may entirely miss some significant point, whatever that is. I'm puzzled why the only SmallTalk I've found which runs on the Mac, namely VisualWorks, has a GUI painter. However, compared to Xcode or even RealBasic (or Hypercard for that matter), the GUI painter seems remarkably primitive, given the length of time VisualWorks and SmallTalk, in general, have been under development. An up-to-date GUI builder with well designed, native widgets seems to me to be a prerequisite for a working software development application. Being required, for example, to program a button from scratch takes one back to the early days of personal computing. What is preventing the various SmallTalks from offering a modern GUI painter?
