There are several debug flags that can be set in pyglet that might help
with debugging this, but I would first suggest a quick poor-man's
debugging, and just throw a few print statements in there. Give the
following a try. It will either tell us where it's hanging, or if it's
another issue such as the windows just not being displayed. It'll at least
be a start to find out where the issue is.
import time
import pyglet
class Figure(pyglet.window.Window):
ID = 0
def __init__(self):
Figure.ID += 1
super(Figure, self).__init__(caption='fig' + str(Figure.ID))
self.fps = pyglet.clock.ClockDisplay()
def on_draw(self):
self.clear()
self.fps.draw()
fig1 = Figure()
fig2 = Figure()
while True:
pyglet.clock.tick()
print("Clock ticked")
for window in pyglet.app.windows:
window.switch_to()
print("switched to window {0}".format(window))
window.dispatch_events()
print("dispatched events")
window.dispatch_event('on_draw')
print("dispatched on_draw event")
window.flip()
print("flipped window\n")
time.sleep(1)
