Removing a method...
by Tony Giaccone 10 Nov '08

10 Nov '08

I'm working with the SeaSide Squeak Image. 5.8-578. Try as I might to be prefect. Sometimes I make a mistake and create a method with a signature it shouldn't have. So I try to use the "Refactor Method-> remove", menu selection. When I do this, I get a waring about "Browse References". If I say no, nothing seems to happen. I I say yes, I get a References To: browser with pointers to other classes where a method (message?) with the same signature is used However, none of those references will ever be to my class, they are made against classes that already exists. I don't want to touch those references, but I do want to remove my method. How do I do that? It's totally not clear to me. Tony

How can I determine what version of a package I have installed in my image. For example, I have Seaside installed, but I don't know what version I have. --- Mark Volkmann

Squeak dies when I click process browser
by farnsworth2008 09 Nov '08

09 Nov '08

I am new to small talk and new to squeak. The first thing I am doing is exploring the user interface by clicking on stuff. Much of what I have seen is very cool and works well but I have also had problems with the system freezing up and becoming unresponsive. The image I am trying to use is: sq3.10.2-7179dev08.11.1.image I tried a couple of other images: sq3.10.2-7179web08.11.1.image SqueakLightII.7212.image In all cases the image freezes up when I try to open the process browser. The system also freezes up at other times. I am using the term "freezes up" to describe the following collection of symptoms: 1) The Mouse pointer moves fine 2) Applications other then the mouse are frozen (i.e. clock stops moving) 3) Dragging stuff around is not working 4) Buttons in all applications are not working Basically the system seems totally frozen at this point such that the only recovery is to shut down squeak and start again. Does the community have any thoughts or tips? -Mark -- View this message in context: http://www.nabble.com/Squeak-dies-when-I-click-process-browser-tp20405720p2… Sent from the Squeak - Beginners mailing list archive at Nabble.com.

Class Instances
by Michael Junginger 06 Nov '08

06 Nov '08

Hi there, I'm trying to find out all the instances of a class. Is this possible? If so, how could I do this? I expected that there exists some method like subclasses where I can find out all subclasses of a class... Thank you very much in advance, Mike

how can I make an application distribution, like eToys
by Albert Lee 06 Nov '08

If I want to develop a commercial software, and deliver the copy to customers. And I want to hide the source code and irrelevant halos, menus, to make the application looks like "a real" product :) how can I do it?

Smalltalk constants
by Delyan Kalchev 06 Nov '08

06 Nov '08

Hi, Is there a good way to create a named constant in Smalltalk. For example the name MyNamedConstant to be constant bind to the number 2 or even to a non-constant object, like the pseudo-variables nil or true are bind to their objects and the programmer cannot change them to point to other objects. Thanks

Is there a program to generate an all classes tree chart?
by Albert Lee 06 Nov '08

06 Nov '08

learning smalltalk, and get some idea of Metaclass and reﬂective. we can use subclasses or allSubclasses to list a Class' subclass, and then, we can generate the inherit tree. so, is there any existing program to generate this chart?

Thanks for the tip--that's really a good way to get a feel for how things behave. For anyone else interested in this thread, I'll also pass on a couple of pages I found helpful: http://www.visoracle.com/squeak/faq/morphic-layout.html http://coweb.cc.gatech.edu/cs2340/3659 -----Original Message----- From: beginners-bounces(a)lists.squeakfoundation.org [mailto:beginners-bounces@lists.squeakfoundation.org] On Behalf Of Herbert König Sent: Tuesday, 4 November 2008 8:07 p.m. To: A friendly place to get answers to even the most basic questions aboutSqueak.

I never know this when I need it, so I take a rectangle and an EllipseMorph from the object catalog, put the ellipse inside the rectangle (red halo, embed into) and then I play with both Morphs layout options. Don't forget to pin both Morphs Menus to the screen. -- Cheers, Herbert _______________________________________________ Beginners mailing list Beginners(a)lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners ********************************************************************** This electronic message together with any attachments is confidential.
