Python + Pygame + PygButton detecting

Question

I'm using Python 3.3 with Pygame and PygButton (low rep don't allow me more than two links) My files at the moment are [int.py http://pastebin.com/sDRhieCG ] and [scene.py http://pastebin.com/Y2Mgsgmr ].

The idea is making a mainloop in int.py the smaller as possible. The code has a commented-out example of the start_screen buttons at the mainloop. It works, but with every new screen the mainloop would be bloated.

So I created a Scene class to apply background, texts and buttons. It works, but I can make the buttons work. E.g. the bquit button doesn't quit the screen (as it did previously when inserted into the mainloop).

I'm trying to create a scene_loop() inside the Scene() to run everything the specific scene has to offer. With a button click it would change scene and such, start a new scene_loop.

I can't seem to add specific methods after the Scene class is instanced, so I created a Scene_Start class to deal with specific methods like the scene_loop and its buttons (since the background is easily placed through the Scene class).

I'm just stuck and can't see a way to resolve this without scrapping everything and starting again.

Help?

tl;dr: 1. PygButton isn't working outside mainloop 2. How can I create a scene_loop that replaces the mainloop for that scene, "unbloating" mainloop (it would only take care of starting the app and changing scenes).

Thank You.

Problem solved. Answering my own question so it can be helpful to others. Each class have a sceneloop method that runs and "replace" the mainloop. This allows for unbloating and isolating any problem into the scene without affecting the other components.

The mainloop:

while True:
    for event in pg.event.get():   
        if event.type == QUIT or (event.type == KEYDOWN and event.key == K_ESCAPE):
            pg.quit()
            sys.exit()
    scene.startscreen.draw()
    scene.startscreen.sceneloop()
    pg.display.update()

A sceneloop example. This is a method inside the Scene_Start(Scene) class, instanced as startscreen as show above in the main loop.

def sceneloop(self):
    while self.scene_loop == True:
        for event in pg.event.get():
            if event.type == QUIT or (event.type == KEYDOWN and event.key == K_ESCAPE):
                pg.quit()
                sys.exit()
            if 'click' in self.bcreate.handleEvent(event): #CREATE
                startcreate.draw()
                startcreate.sceneloop()
            if 'click' in self.bstart.handleEvent(event): #START
                pg.quit()
                sys.exit()
            if 'click' in self.bload.handleEvent(event): #LOAD
                startload.draw()
                startload.sceneloop()
            if 'click' in self.boptions.handleEvent(event): #OPTIONS
                startoptions.draw()
                startoptions.sceneloop()
            if 'click' in self.bquit.handleEvent(event): #QUIT
                pg.quit()
                sys.exit()
        self.update()
