Better editor components?
by Marcin Tustin 14 Jun '07

14 Jun '07

I've been playing around with SeaSide tutorials, using the class browser and the workspace - is this the right way to do things? The text editing there is pretty sucky for a man used to xemacs, so I ask: is there a better "application" for editing code, or can I get hold of a better generic editor component that can be dropped in to replace the one the browser and workspace are using?

Fishing for a Masters Thesis Topic
by Robert Stehwien 13 Jun '07

13 Jun '07

I've been primarily a Windows C++ developer for 12 years with a little Java, Perl, Python, and lately Ruby along the way. I've never looked at line of Smalltalk until recently. But that all changed when I decided to get a Masters in CS and since a PhD isn't out of the question write a thesis. When asked by a co-worker what my thesis topic would be, I said "maybe something with peer-to-peer, gaming, collaborative environments, 3D, education, visual programming, interaction design, or languages" (big list I know but somewhat ordered). I started digging around and noticed a pattern... Smalltalk, Squeak, Croquet, and Seaside kept coming up (although it took a little while to notice the mouse icon and 3d bunny. So I've ordered the book "Object Land", downloaded all the free books and Squeak (ordered the DVD too), and joined the list. But I'm still having trouble narrowing down a thesis topic to present to my advisor (for adjustment I'm sure). Anyone have any suggestions for a thesis topic? Maybe there is some part of Squeak that the community would like documented/researched/implemented. P2P gaming/collaboration using Croquet sound interesting, but I'm pretty open for suggestions. Thanks, Robert PS: As a working C++ developer it will take a while for me to finish the thesis and my masters.

web based game development in squeak
by gent 12 Jun '07

12 Jun '07

Hi I'd like to develop a simple strategy game that runs from the browser for my website. Can Squeak compile an application in Java or Flash or any other format a browser would recognize without exotic plugins? -- View this message in context: http://www.nabble.com/web-based-game-development-in-squeak-tf3898123.html#a… Sent from the Squeak - Beginners mailing list archive at Nabble.com.

Where is BytecodeGenerator?
by Damian Dobroczyński 06 Jun '07

06 Jun '07

Hi list, What image/VM I should use to get WriteBarrier working (methods contains references to non-existent BytecodeGenerator class)? Documentation says that it should be Squeak 3.7 which means VM v. 3.7 or image v. 3.7? Currently, I use VM ver.3.7 (http://ftp.squeak.org/current_stable/win/Squeak-Win32-3.7.1-VM.zip) and developement image (http://damien.cassou.free.fr/squeak-dev) Damian

usage of PluggableListMorph
by Konrad.Krentz 06 Jun '07

06 Jun '07

Hi all, I've got troubles using PluggableListMorph. I just need a ListBox to put some strings into it. The first problem happens when I open a PListMorph in world - can't drag it. Secondly I have no idea how to put my choice items into the PListMorph. I tried list: but it doesn't work. It would also be very interesting to me if someone knew a method, which returns a collection of all subclass instances of a certain class. Thanks for your answers Konrad

closing/deleting a morph and dependents
by Dietmar Schielke 05 Jun '07

05 Jun '07

Hi Squeakers, i made a simple morph with submorphs. the submorphs are views for some domain objects and are dependents of them ( domainobj addDependent: mysubmorph ). Every thing works fine :-) but i can't figure out, how to remove my submorphs from the dependents list of my domain object, when I close/delete my morphic gui. It seems Morph delete does not call delete recursively on its submorphs. Is there an other way submorphs get informed when they are removed from the screen? Thanks in advance, Dietmar

invoking a *class* method from a workspace
by mstram 05 Jun '07

05 Jun '07

What's the trick / catch ... if there is one for invoking a class method from a workspace? I created a Class "MikeTest". - Added an instance method : "imethod" MikeTest >> imethod ^ 'I am an instance method' - Added a Class method MikeTest class>>cmethod ^ 'I am a class method' ---- Then in a workspace : t := MikeTest new. t imethod (alt-p) -->> 'I am an instance method' (As expected) t cmethod (alt-p) gives 'MessageNotUnderstood' http://mstram.freepgs.com/img/message_not_understood_when_evaluating_class_… The debug trace has 'UndefinedObject>>Doit' ... which seems strange to me ... does that mean the workspace doesn't understand how to send a class method ??? Puzzled (again).

Objects with #startUp: when Squeak starts
by Damian Dobroczyński 05 Jun '07

05 Jun '07

Hi list, I experimented with Magma objects in a Workspace window. Unfortunately, after destroying this window several objects still exists and they are invoked at the startup (just after or while the image is loaded) with #startUp: message. I'd be very happy to remove some of these objects from the "start-up" list because they make some trouble (for example trying to read some files which do not exists any more). I assume that the start-up list of objects this is a sort of standard feature for Squeak? D.

The VM version does not need to match the Image version. In fact, at the moment I'm running a Squeak VM version 3.3 on my PDA with the 3.8 image, and it works fine. The 64-bit VM can run both 32-bit images and 64-bit images. Unfortunately, I can't remember how this worked. If I remember correctly, you could compile two binaries - one for 32-bit images and one for 64-bit images. I also believe that the 64-bit VM was originally made because the 32-bit VM didn't work at all on 64-bit architectures. Can anybody else confirm this? Also make sure that you have the ia32-libs Ubuntu package installed - this may magically make the 32-bit VMs work. Michael.
