How to use pyglet within a class

class, overriding, pyglet, python

Solution

You can inherit from Window. This should work:

class Frontend(pyglet.window.Window):
    def __init__(self, xs, ys):
        self.GameInstance = Board(xs,ys)
        super().__init__(width=512, height=512,visible=False)

    def on_draw(self):
        self.clear()

Your code is not working because you can not reference the instance of the Frontend class outside the methods. If you will have only one instance of the Frontend class you can do something like:

class Frontend:
    window = pyglet.window.Window()
    def __init__(self):
        ...
    @window.event
    def on_draw():
        ...

Problem

In all the tutorials on the web I've seen with Pyglet, it doesnt seems that any of them have used classes to contain the pyglet.window.Window instance. For example, most tutorials seem to go something like ``` import pyglet game_window = pyglet.window.Window() @game_window.event def on_draw(): #dostuff while __name__ == "__main__": pyglet.app.run() ``` I'm having trouble restructuring this code into a class. My code which is intended to do so, is here: ``` import pyglet from pyglet.gl import * from Board import Board class Frontend: def __init__(self,xs, ys): self.GameInstance = Board(xs,ys) self.GameWindow = pyglet.window.Window(width=512, height=512,visible=False) @GameWindow.event def on_draw(self): self.GameWindow.clear() f = Frontend() ``` When I run this code, I get the following error: ``` Traceback (most recent call last): File "C:/Users/PycharmProjects/Nothing/2048/Frontend.py", line 7, in <module> class Frontend: File "C:/Users/PycharmProjects/Nothing/2048/Frontend.py", line 13, in Frontend @GameWindow.event NameError: name 'GameWindow' is not defined ``` When I replace `@GameWindow.event` with `@self.GameWindow.event` in an attempt to resolve the NameError I get: ``` Traceback (most recent call last): File "C:/Users/PycharmProjects/Nothing/2048/Frontend.py", line 7, in <module> class Frontend: File "C:/Users/PycharmProjects/Nothing/2048/Frontend.py", line 13, in Frontend @self.GameWindow.event NameError: name 'self' is not defined ``` Which i expect. However, I'm not sure why this code isnt working - can someone explain why and how to fix it?
