If you navigate inside a class, for example AColorSelectorMorph, you can see all its properties and one of them is environment, if you go inside it, you get again all classes in the system dictionary.

For example, if you evaluate: Foo new. Thanks Mariano. May be my question was not well explained. Of course if I evaluate: Foo new, I get into a infinite loop. 1st question, when I'm inspecting, I'm evaluating? In the case that I mention above (Class enviroment) I got all classes in the system and each of them has an environment, that is all classes, and so on. Here, we have a infinite recursion. So, how the inspector get a lazy visualization of the it? Greetings

Re: [Pharo-project] Some questions about pharo

The Windows vm displays a system tray icon that allows the image to leave the headless state. It has been quite useful, but there should be (hopefully is) a way to prevent that. ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of Lukas Renggli [renggli(a)gmail.com] Sent: Monday, October 18, 2010 2:09 PM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] Some questions about pharo See <http://book.seaside.st/book/advanced/deployment/maintaining/vnc>.
