When you want to break out, just do a normal return! This often even makes the code more readable. But speaking of tricks... testValueWithExitBreak | val | [ :break | 1 to: 10 do: [ :i | val := i. i = 4 ifTrue: [break value]. ] ] valueWithExit. self assert: val = 4. testValueWithExitContinue | val last | val := 0. 1 to: 10 do: [ :i | [ :continue | i = 4 ifTrue: [continue value]. val := val + 1. last := i ] valueWithExit. ]. self assert: val = 9. self assert: last = 10. with BlockClosure>>valueWithExit self value: [ ^nil ] -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe.

[Pharo-project] opening an OS window from within Pharo, to present a file directory ?

by Torsten Bergmann

>Is there behavior for doing this in Pharo ? >"self openOSWindowOn: aFileDirectory " Your question can mean two things: 1. You ask for a file/folder selection dialog where the user selects a file or folder and you get the name back into Pharo: If you want to use the built in functionality use Polymorphs "FileDialogWindow" by using the services in UITheme class. (see references to class FileDialogWindow. But thats not an OS window. If you want to open an OS ("native") file/folder selection dialog from Pharo then there is currently no platform independent solution. AFAIK until today there is no primitive to do that. Maybe because the OS-systems are not uniform here. For Windows there is a plugin for the open/save dialog provided by the Win32-API: http://kminami.fc2web.com/Squeak/Goodies/Win32FileDialogPlugin/index.html *Side note: Pharo has the same situation as Java here. By default there is an own implementation FileDialogWindow/JFileChooser that does not feel like the native one. Another interpretation of your question: 2. You ask for a way to open a native file explorer/browser window on a given file/directory just to show the contents using the native window: You can use FFI for that on Windows: Win32Shell new shellOpen: 'c:\' Since most browsers display the directory structure and files too you can use the external web browser package and a file URL (see ConfigurationOfExternalWebBrowser) ExternalWebBrowser openOnUrl: 'file://c:/temp' Bye Torsten -- Neu: GMX De-Mail - Einfach wie E-Mail, sicher wie ein Brief!

Re: [Pharo-project] About SimpleMorphic

by Juan Vuletich

Hi Folks, WRT Layout APIs, SimpleMorphic includes the same simplified version of LayoutFrame as Cuis. Cuis also includes a new approach, implemented in LayoutSpec and LayoutMorph. I did this for an application that requies adding new widgets without specifying a new layout for all of them. It is also nicer than LayoutFrame, and will replace it at some moment. But it is not used at all by SimpleMorphic or Cuis, and that's why I did not include it in SimpleMorphic for Pharo. But you might open Cuis and take a look it, and load it in Pharo if you like. Try the example class methods in LayoutMorph, and resize the morph to see what it can do. Cheers, Juan Vuletich
