The activity must create a single PygameCanvas widget:
self._canvas = sugargame.canvas.PygameCanvas(self)
self._canvas = sugargame.canvas.PygameCanvas(self)
self.set_canvas(self._canvas)
self.set_canvas(self._canvas)
The activity may assign keyboard focus to the PygameCanvas widget, so that keyboard events generate pygame events:
self._canvas.grab_focus()
The activity must call the run_pygame method of the PygameCanvas widget, passing the main loop function of the Pygame program.
# Start the game running.
# Start the game running.
self._canvas.run_pygame(self.game.run)
self._canvas.run_pygame(self.game.run)

== Differences between Sugargame and olpcgames ==
The olpcgames framework provides a wrapper around Pygame which attempts to
allow a Pygame program to run mostly unmodified under Sugar. To this end,
the Pygame program is run in a separate thread with its own Pygame message
loop while the main thread runs the GTK message loop. Also, olpcgames wraps
Sugar APIs such as the journal and mesh into a Pygame-like API.
Sugargame takes a simpler approach; it provides a way to embed Pygame into a
GTK widget. The Sugar APIs are used to interact with Sugar, the Pygame APIs
are used for the game.
Sugargame advantages:
* Simpler code
* More elegant interface between Pygame and GTK
* Runs as a single thread: no thread related segfaults
* Possible to use Sugar widgets with Pygame
Sugargame limitations:
* No support for Pango or SVG sprites (yet)
