The problem is here rowPlayer add: (textPlayer at:i) ; add:#captainButton; add: (buttonStartingEleven at:i). ]. As you see, the argument of add: is a symbol, but in the first and third add, you add directly a TextInputFieldModel In addition your usage of class inst var is a bit disturbing :) Ben On 22 Nov 2013, at 11:08, prova email <prova213(a)hotmail.it> wrote: > Hi Ben, > here the .st file, there are some comments in italian, i hope it's not a problem. > I know that Spec is the most used and it will be the standard GUI builders in the future, so i'd like to find a solution here, without changing to Morph and Polymorphic. > > Paolo > > From: Benjamin.VanRyseghem.Pharo(a)gmail.com > Date: Fri, 22 Nov 2013 11:04:53 +0100 > To: pharo-users(a)lists.pharo.org > Subject: Re: [Pharo-users] Writing a GUI - Where to start? > > It seems that you return the wrong object somewhere :) > > Could you commit your code somewhere so I can have a look ? > > > Ben > > On 22 Nov 2013, at 11:01, prova email <prova213(a)hotmail.it> wrote: > > I started to use Spec, i love nested layouts and so on.

Re: [Pharo-users] How to load the PetitPHPParser?

by Tudor Girba

Hmm. That cannot really be. PPCompositeParser is defined in PetitParser, but likely the problem comes from the way the ConfigurationOfPetitPHPParser defines the dependency to PetitParser: spec project: 'PetitParser for PetitPHPParser' with: [ spec className: 'ConfigurationOfPetitParser'; file: 'ConfigurationOfPetitParser'; version: 'default'; repository: 'http://source.lukas-renggli.ch/petit' ]. It should load PetitParser from STHub: spec className: 'ConfigurationOfPetitParser'; file: 'ConfigurationOfPetitParser'; version: #development; repository: 'http://www.smalltalkhub.com/mc/Moose/PetitParser/main' Cheers, Doru On Sun, Nov 24, 2013 at 8:43 AM, HernÃ¡n Morales Durand < hernan.morales(a)gmail.com> wrote: > Hi Doru, > > I have tested loading PetitParser from the ConfigurationBrowser and > without, and it is the same. > > > > 2013/11/24 Tudor Girba <tudor(a)tudorgirba.com> > >> From the errors, it seems that you have to load PetitParser first. >> >> Doru >> >> >> On Sun, Nov 24, 2013 at 4:48 AM, HernÃ¡n Morales Durand < >> hernan.morales(a)gmail.com> wrote: >> >>> Loading in Pharo 2.0 gives warning with lots of dependencies: >>> >>> This package depends on the following classes: >>> PPCompositeParserTest >>> PPCompositeParser >>> You must resolve these dependencies before you will be able to load >>> these definitions: >>> PPPHPCoreGrammar >>> ... >>> >>> I have used: >>> >>> Gofer new >>> squeaksource: 'PetitPHPParser'; >>> package: 'ConfigurationOfPetitPHPParser'; >>> load. >>> (Smalltalk at: #ConfigurationOfPetitPHPParser) perform: #loadDefault. >>> >>> >>> >>> Cheers, >>> >>> HernÃ¡n >>> >> >> >> >> -- >> www.tudorgirba.com >> >> "Every thing has its own flow" >> > > -- www.tudorgirba.com "Every thing has its own flow"

A more verbose form is: self nbCallout stdcall; options: #( - optDirectProxyFnAddress optAllowExternalAddressPtr); function: #( NBBootstrapUlong HeapAlloc (ulong heapHandle , 0 , SIZE_T size) ) module: #Kernel32 But be aware though, that this code usually invoked once during code generation, and later no method code is invoked because it just runs a primitive (primitiveNativeCall), and if it succeeds, it just returns with result, without running a method's body. So, nbcall can be changed/extended if you need extra thing at code generation stage, or you want to handle primitive error(s) differently. But not for handling things like function return values (which happens to be a library's error/success code). -- Best regards, Igor Stasenko.

Re: [Pharo-users] [Athens] Finding if a line passes through a specific pixel .

by Igor Stasenko

There is some bits which can help you in this regard. The part of it is path tesseleration, which turns any path with complex curves into polygon (which has only straight lines), from there on, i think you can easily calculate the distance between any point and that polygon. Look at AthensCurveFlattener class, and its uses. the entry point is (flattenPath: aPath transform: aTransformation).
