Compatibility Tips

SUGAR_BUNDLE_VERSION

Some earlier OLPC builds (e.g., 703) do not have a bundle version environment variable, so you need to catch an exception if you want to access the version.

try:
    version = os.environ['SUGAR_BUNDLE_VERSION']
except:
    version = "unknown"

Screen size

The screen size varies on different hardware platforms. If you develop in an emulator, it is worthwhile trying different sizes to make sure your activity scales properly.

Some useful utilities:

width = gtk.gdk.screen_width()
height = gtk.gdk.screen_height()

toolbox = activity.ActivityToolbox(self)
toolboxheight = toolbox._activity_toolbar.size_request()[1]
