Hi, El 02/08/11 15:08, StÃ©phane Ducasse escribiÃ³: > You should have a look at TreeMorph and friends. > I'm sure that you can build a leo based system. > The timeProfiler is also an example of how to use the TreeMorph > Stef > Thanks. As a newbie, I think that I'm not quite ready to browse the classes and methods and start from there, so I will use Glamour and the thesis from Phillip Bunge as an starting point for this exploration, putting questions here when they come. Having comprehensive documentation is a good thing for any complex tool we want to learn and is a joy to read things like PBE, Seaside Tutorial and the Glamour Thesis. I hope to read most docs like these and hopefully help also with its creation. Cheers, Offray Ps: there also a lot of good blogs in the Smalltalk noosphere.

Hi Igor, Thanks for your advice.

I have used previously Leo mainly for documentation and not for programming because I'm not a programmer, but I think that is time to learn it and I want to do it with Pharo/Smalltalk (but keeping python in my belt anyway because of it uses in another fields of my interest). One of the things I like more about Leo is the fact that you can organize any kind of information in a integrated emergent tree and has a nice feature, called "Clones" so the same nodes in a tree can be put in an arbitrary place and be changed in synchrony, creating different ways of see the information inside the tree. In contrast with this experience, workspaces look and feel a lot plain. I'm using them to document my learning in Pharo/Smalltalk and I create different workspaces for this preliminary exploration: one for Seaside, one for Aida, One for Moose, and one for PBE. They include not only code snippets but also text, not the kind of text that you will put on classes of methods, but the one that you will put on a blog post, interchanging text and code snippets. Thats why I want to create a tree like workspace. I will keep you posted and made the usual newbie questions. Thanks, Offray

polymorph question

by Werner Kassens

Hi, i have a subclass of PluggableTextFieldMorph. somewhere in the code i set its contents with: self textMorph contents: aString . this sets the textcursor to the first position and makes him unvisible. what i want to do is set the cursor to the last position and make him visible (and movable). i tried it with: self textMorph editor selectAt: textMorph asText size +1 . which does indeed what i want, but the textcurser is now unmovable by the cursor keys. how do i make the cursor movable again? i tried it eg with: self textMorph editor unselect . but of course this did not work, instead it produced an error because unselect calls markBlock: which does not exist. when i changed TextEditor>>unselect to: self editingState markBlock: self pointBlock copy the error vanished, but it did not help . Hence my question, how do i make the textcursor movable by the cursor keys? ( or move the cursor in a less intrusive way than with selectAt: ) as an aside, i noticed that focusChanged in PluggableTextFieldMorph is not called at every focus change. in my subclass i first tried changing keyboardFocusChange: in the obvious way, but interestingly this does not help in _every_ case, i needed to change navigateFocusBackward and navigateFocusForward. of course this has nothing to do with my question. werner

Re: [Pharo-users] Pharo 1.2.1

by Marcus Denker

Hello, The Book (sadly) describes a quite old version of Pharo (1.0 with a special Code Browser). In the meantime, we changed (improved, simplified) *a lot* of things... The problem is that it's futile to try to keep the book up to date. We will make a new one for 2.0 :-) So the best is to use the version linked from http://pharobyexample.org/ https://gforge.inria.fr/frs/download.php/27023/PBE-1.0.zip when doing exercises from the book.

Pharo 1.2.1

by David Perkins

Hello! I just downloaded Pharo 1.2.1 on my Mac OS X.5, and am also reading a printed copy of "Pharo By Example Version 2010-02-01" in order to learn Smalltalk. In the Quick Tour chapter, you show the Preference Browser, but I am unable to bring this up using the System ... menu option. Does it need to be installed separately? Also in the Quick Tour chapter, you give an example BouncingAtomsMorph new openInWorld, which fails with the message "unknown variable BouncingAtomsMorph ...". Does this also need installation? Please forgive my beginner questions. Thanks!! David Perkins kinetiks(a)verizon.net
