Recent versions of OLPCGames have a customisation point:
def build_toolbar( self ):
"""Build our Activity toolbar for the Sugar system
This is a customisation point for those games which want to
provide custom toolbars when running under Sugar.
"""
the default implementation (available in activity.py for your
inspection) just creates an activity.ActivityToolbar and sets a few
callbacks on the "share" widget. You can read the code in
olpcgames/activity.py if you want to see how it all works.
You will likely want to override build_toolbar something like this:
def build_toolbar( self ):
"""Add my extra widgets to the toolbar
"""
toolbar = super( MyActivityClass, self ).build_toolbar()
# your custom widgets added here...
return toolbar
all of this code, including any callbacks you register, are going to
happen in the GTK mainloop, so if you are passing messages to your
Pygame code you will likely need to use a queue or Pygame events to get
the messages over to the Pygame side. You can see an example of
defining a toolbar in the terminal activity... hmm, and reading that it
seems that someone has changed the original "toolbar" class to a
"toolbox" class, so we'll probably have to update OLPCGames to support that.
Anyway, hope that gets you started,
Mike
