Re: [Pharo-users] Strange behaviour of abstract method
Michael, On 31 Oct 2013, at 11:00, Michael Paap mp...@netcologne.de wrote: Hello list, in our OOP course we noticed some behaviour of an abstract method, which I cannot explain. Maybe you can help me: If I do the following SequenceableCollection new add: 123 I would expect an Error. The method add: is not implemented in SequenceableCollectionbut inherited from collection, where it's only statement is self subclassResponsibility But in reality, Pharo seems to enter an endless loop, consuming more and more memory. Can someone please explain to me, what happens here? Greetings, Michael Obviously, abstract classes should not be instanciated, but in teaching this is bound to happen. Now, the actual error happens in the environment (debugger, inspector, printString mechanisms): they see a collection and try to work with it, since it is an incomplete/degenerate one, things break/loop. The following does work for example: SequenceableCollection new isCollection. The question is: should there be an explicit error message when an abstract class is instanciated, is that even possible ? Sven
[Pharo-users] Create a .exe application in Pharo 2.0
Hi Everybody, i'd like to know what can i have to do to create a .exe application/desktop application, after creating a Package with all the working classes in Pharo 2.0. I created the Minesweeper game, and i'm tired to write into the workspace MSGame new openInWorld. How can i automatize that?Thanks for the help guys! W Pharo!Paolo
Re: [Pharo-users] Create a .exe application in Pharo 2.0
What you can do here, is using the preferences to automatically start your app when a pharo image is open :) Then your Pharo.exe+your image will turn into a Minesweeper :) Ben On 31 Oct 2013, at 15:01, Paolo Piccinelli captai...@hotmail.it wrote: Hi Everybody, i'd like to know what can i have to do to create a .exe application/desktop application, after creating a Package with all the working classes in Pharo 2.0.

Re: [Pharo-users] Create a .exe application in Pharo 2.0
Will preferences work if the application is distributed to other machines. I guess it might work if the preferences file sits next to the image file, but not automatically if it was installed on another machine via a ConfigurationOfXXX. The other alternative may be to plug into the #startup mechanism. Take a look at the class PhLDeploymentScript in PharoLauncher [1]. Also you might find some interesting tips to carry over from [2] - but be aware that is written for old version Squeak 3.9.

Re: [Pharo-users] CogVM arguments in Win32
You can try something like this: | handle window | handle := NativeBoost forCurrentPlatform squeakWindowHandle. window := NBWin32Window new value: handle; yourself. window hide. or window setWindowText: 'im a main window blablabla'. :) i didn't tested it since its been implemented, but i think it should work.
