hi As promised here it goes a widgets tookit that can be used with ChucK. We decided to call it Zombie GUI server, as it can be taken control from ChucK (and soon supercollider hopefully). This is the address for download source, docs and examples http://www.ixi-software.net/content/download/zombie0.1.zip These are for windows and mac standalone servers (testing) http://www.ixi-software.net/content/download/zombie_win_exe.zip http://www.ixi-software.net/content/download/zombie_mac_app.zip We tested the mac standalone on 10.4 and it seems to work fine, please let us know of any problems. You might want to use the source zombie.py but then you need the following dependencies: wxpython, simpleOSC There are two ways to use it, the first is to work with python extending the zombie.py class source, this is probably the easier way as the code is really minimal and there is no need to know python, check python_example.py for details. The second way to use it is from ChucK (using both the standalone or the source). This is a bit more complex but not much more really. We provide a set of classes that make life easier to communicate to the server from ChucK. Check the chuck_basic.ck example. Note that most of the file is the class provided that talks to the python server, there is only need to change the bottom part of the file. I am not sure if this is the best way to organise the code in ChucK. I tried to hide all the code into another file so that we end up a very simple file that contains only the stuff needed to edit and the rest is in another file, but there are few things in current ChucK that prevented me from doing this. On the one hand it is only possible to have one public class per file, on the other hand there is no import or include yet implemented. It would be great to have some system like supercollider has to put all the user defined classes on a folder like libraries. So if anyone finds a better way to organise the code on the chuck example we would be very happy to change them. Next step are to make it compatible with supercollider and to add more flexibility to the system. Please check the readme.txt file for more details on the API and more documentation like how to create standalone applications etc... Please let us know of any problems or experiences using this. We hope this helps developing GUIs for ChucK. enrike
