I've made a subclass of Window, but any use of the mouse event methods
throws a TypeError complaining about incompatible function signatures.
----------------
import pyglet
class MyWindow(pyglet.window.Window):
CAPTION = 'MyWindow'
WIDTH = 800
HEIGHT = 600
def __init__(self):
super(MyWindow, self).__init__(
width = MyWindow.WIDTH,
height = MyWindow.HEIGHT,
caption = MyWindow.CAPTION)
def on_mouse_press(x, y, button, modifiers):
pass
def on_mouse_release(x, y, button, modifiers):
pass
def on_mouse_drag(x, y, dx, dy, buttons, modifiers):
pass
def on_draw(self):
self.clear()
if __name__ == '__main__':
window = MyWindow()
pyglet.app.run()
----------------
This is the error I get for mouse presses:

This is the error I get for mouse releases:
