Eventloop in Pyglet is a great feature when we want to control or integrate run() into another loop (eg: reactor.run() on twisted). In their documentation, http://www.pyglet.org/doc/programming_guide/customising_the_event_loop.html, the example of using custom eventloop in pyglet isn’t clear.
Here is example how to use EventLoop() in Pyglet to control the loop without pyglet.app.run():
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | from pyglet import window, text, app, resource, event, clock event_loop = app.EventLoop() fps_display = clock.ClockDisplay() window = window.Window() image = resource.image("ball.png") @window.event def on_draw(): window.clear() image.blit(100, 100) fps_display.draw() @event_loop.event def on_window_close(window): event_loop.exit() return event.EVENT_HANDLED def main(): event_loop.run() if __name__ == "__main__": main() |
So, basically, we create a new instance from EventLoop by:
1 | event_loop = app.EventLoop() |
And we can start this event_loop by execute run() method from the instance.
