Pay attention because we saw a lot of people doing the same. Designing a new set of widgets is a HUGE effort. For the use of 3d I do not see any point doing that. A valuable effort would be to check the polymorph widgets that are worth. - Remove broken or useless morphic widgets. - improve existing widgets - as an example alain plantec designed and implemented a new tree with much much better capabilities than the default one and we are waiting that he finishes to integrate into pharo - At esug alain show us a first attempt to use cairo to build a new "morphic" and there widgets will also be missing. I think that having a layout manager (copying may be the one of sophie) is more important than new widgets because how do the components move when you resize a window or the relative placement of widgets is also important. > I added new features; can be viewed here: > > Inlaying a view into another > http://www.youtube.com/watch?v=L0dSuunKbEM > > Adding external files (images only) for use in UIBuilder > http://www.youtube.com/watch?v=UXvwieFA_4k > > Building a context menu > http://www.youtube.com/watch?v=cilG97m4u2g > > > For probe the designer only type > > view := CLUIBuilderMainForm new show. > > in a workspace. > > > I want to be thankful to Jordi Delgado and Citilab for Smalltalk > initiative > and lessons, and future events ( ESUG 2010 :) ) > > > Regards > -- > View this message in context: http://n2.nabble.com/CLFramework-UIBuilder-tp3594252p3594252.html > Sent from the Pharo Smalltalk mailing list archive at Nabble.com. > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project

I committed my image segment tests to the inbox (Tests-AdrianLienhard. 19). There are some initial tests in ImageSegmentTest (one fails, which documents a problem of loading symbols). I also implemented support code that allows one to analyze a segment binary (i.e., to iterate over the instances in the segment without instantiating the objects). This should simplify writing more tests. Cheers, Adrian [...] ___________________ http://www.adrian-lienhard.ch/ Great! Thanks! I'll start exploring adding more tests for this area. Sheridan

Re: [Pharo-project] Building a VM and/or plugins

by Schwab,Wilhelm K

Ken, That's interesting, and might be particularly so to anyone who cares about doing things efficiently on Windows. I say that because there is some perhaps dated literature from the NT days that dismantled the conventional wisdom that native threads always beat green threads. Basically, they found that the NT schueduler was fairly pathetic and that a good green thread scheduler handing out asynch events would beat its fumblings with blocking calls. For now, I am far more concerned about coding something in a reasonble time than trying to keep up with Amazon's web traffic. The asynch side of OpenSSL is very flexible, and IIRC, **very** complicated. For now, I would be happy to get the blocking calls working and to signal semaphores or raise errors when they complete. That should be enough to let the image keep running when the outside world does not answer quickly for any reason.

I would think a separate thread (or process) is required to handle and recover from bad pointer references. For general client/server multiplexing however, you might look at liboop for ideas: http://liboop.ofb.net/ "Liboop is a low-level event loop management library for POSIX-based operating systems. It supports the development of modular, multiplexed applications which may respond to events from several sources. It replaces the "select() loop" and allows the registration of event handlers for file and network I/O, timers and signals. Since processes use these mechanisms for almost all external communication, liboop can be used as the basis for almost any application." There are refs to other event dispatchers on the liboop web page.

Heh. With very little effort I created a window with a button, pushed the button, and got a nice "Hello World" in the Transcript...
