How to switch default browser
by Rich 02 Aug '06

02 Aug '06

How would one go about switching the default browser? I remember at one point switching from the standard Squeak browser to the Refactoring Browser, but since found out that OmniBrowser is the Squeak browser of choice (if I'm wrong about this please let me know) but can't figure out how to switch the default to OmniBrowser. I know I have it installed and can open it manually from the workspace, but it would be nice if I could switch the default. Thanks everybody. -Rich

I just tried to open SqueakMap package loader and got this option: "The map on disk is more than 10 days old. Update it from the internet?" I chose "Yes", and got an error: "Reading an instance of ByteSymbol - which modern class should it translate to?" Any suggestions or workarounds? Thanks.

Returning focus to caller
by Jesus Alvarez 30 Jul '06

30 Jul '06

I have a Squeak application that has a main window (SystemWindow) and sometimes opens dialog windows to request user input (also SystemWindows). When a dialog is closed, I would like to return keyboard and mouse focus to the caller. I tried returnFocus (model isMorph) ifTrue: [ self currentHand newKeyboardFocus: model. self currentHand newMouseFocus: model.]. but that doesn't work. If several windows are open, it can return to a window other than the caller. BTW - The model is the caller window. What is the recommended way to return focus to a previous window? Thanks.

Can't file in project with SqueakMap code in it
by Mike O'Brien 29 Jul '06

29 Jul '06

I filed out a project with a SqueakMap package in it (in addition to my own code). Attempting to file it into a clean 3.8-6665 image fails. The package in question is XPMReadWriter, and after grinding a bit, I get a Debugger: UndefinedObject(Object) >> doesNotUnderstand: #commentStamp:prior: The Compiler is trying to evaluate: 'XPMReadWriter commentStamp: ''<historical>'' prior: 0' XPMReadWriter isn't defined at this point. Is this a problem with the order in which Project files are written? It's just possible that I first loaded XPMReadWriter before creating this project, then loaded it in again. Would this result in such a Project file? The problem was cured by manually loading the XPMReadWriter SqueakMap package first, then filing in the Project. That worked fine. I'm just trying to understand what happened. FWIW, though, when the project opened up, all of the previously existing windows had bold-face font in all panes. New windows were created using the correct font, however. Weird. Mike O'Brien

Splitting strings
by Damien Pollet 28 Jul '06

28 Jul '06

Hi, is there anything like ruby's String#split in Smalltalk? (split the string at string occurences or regexp matches) I found SequenceableCollection#piecesCutWhere: or String#findTokens but I need to split at occurences of a substring. I must also admit my problem is with VW... I did try in the method finder in Squeak, but without much success. -- Damien Pollet type less, do more
