Hello people I have a problem using canvas. olpcgames canvas has 2 arguments: width and height. In my activity class I call canvas in this way: self.canvas = olpcgames.canvas(1200, 750) but I have this problem: olpcgames.canvas: Uncaught top-level exception: Traceback (most recent call last):   File "/home/monyu/Activities/StoryBuilder.activity/olpcgames/canvas.py", line 116, in _start     fn() TypeError: __init__() takes exactly 2 arguments (1 given) Exception in thread Thread-1: Traceback (most recent call last):   File "/usr/lib/python2.5/threading.py", line 486, in __bootstrap_inner     self.run()   File "/usr/lib/python2.5/threading.py", line 446, in run     self.__target(*self.__args, **self.__kwargs)   File "/home/monyu/Activities/StoryBuilder.activity/olpcgames/canvas.py", line 124, in _start     gtk.main_quit() RuntimeError: called outside of a mainloop I reviewed several olpcgames activities but I don't understand how to show the content of my game into the canvas, so I was following the Activity tutorial but I got the same log. reviewed the olpcgames canvas source code and the method connect_game is looking for the name of activity main loop, but I don't know how to set it on. if ':' not in app:  app += ':main'  mod_name, fn_name = app.split(':')  mod = __import__(mod_name, globals(), locals(), [])  fn = getattr(mod, fn_name) any hints Thanks -- -------------------------------------------- + Software Libre en Colombia <a href="http://el-directorio.org">http://el-directorio.org</a> + OLPC Colombia <a href="http://wiki.laptop.org/go/OLPC_Colombia">http://wiki.laptop.org/go/OLPC_Colombia</a> + Mujeres en el software libre <a href="http://www.chicaslinux.org">http://www.chicaslinux.org</a>
