ATB error

[rougier]

Citing Todd Marshall (unable to contact him):

I just was trying to use your atb python wrapper for AntTweakBar on Ubuntu 64bit 12.10. I downloaded your

http://www.loria.fr/~rougier/downloads/atb-python.tgz

directly from you and ran "sudo setup.py install". I tried your demo_glut.py and it crashed complaining about glumpy.key not existing. Maybe the newer version of glumpy used to have glumpy.key and has since moved it to glumpy.window.key etc

I had to make two simple changes in handlers_glut.py to get the demo_glut.py to run.

add "window" to achieve the following everywhere

glumpy.key --> glumpy.window.key
glumpy.mouse ---> glumpy.window.mouse

in VI I just did the following substitutions
%s/<glumpy.key>\C/glumpy.window.key/gp
%s/<glumpy.mouse>\C/glumpy.window.mouse/gp

Also, in demo_glut.py had to change

import trackball

to

import atb.trackball as trackball

This is Todd Marshall. Thanks for opening this issue. In the meantime, I made an account here ...

Yep, I feared not being able to contact you since the mailer daemon bounced back my anwser.

atb-python is currently broken because glumpy should not appear at all in source, it is supposed to be self-contained and only use GLUT. Do you have a fix by any chance ?

[pocdn]

A possible fix is to just remove glumpy in handlers_glut.py and set the keyboard/mouse mappings directly. Here's my version that does that; Note I chose to use an arbitrary naming convention of "local" but it may make sense to be something like "_pyatb_glut" to better delineate what this is for or if someone wants to add bindings to GLF/SDL/etc later.
