Почему Pygame отображает черный экран? ⇐ Python

[Anonymous]

Мой Pygame не устарел, поскольку у меня работала предыдущая версия кода. Когда я запускаю код, я получаю черный экран:

Код: Выделить всё

import pygame
import sys
from pygame.locals import *

white = (255,255,255)
black = (0,0,0)
objs = []

MAIN_BUTTON = 1

class Pane():

def __init__(self):
self.Screen = pygame.display.set_mode((1000,600), 0, 32)
self.font = pygame.font.SysFont('Arial', 25)

def drawPane(self, textToDisplay):
self.Screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))
pygame.draw.rect(self.Screen, (black), (175, 75, 200, 100), 2)

def drawPane1(self, textToDisplay):
self.Screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))
pygame.draw.rect(self.Screen, (black), (175, 75, 200, 100), 2)

def drawPane2(self, textToDisplay):
self.Screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))
pygame.draw.rect(self.Screen, (black), (175, 75, 200, 100), 2)

def drawPane3(self, textToDisplay):
self.Screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))
pygame.draw.rect(self.Screen, (black), (175, 75, 200, 100), 2)

def drawPane4(self, textToDisplay):
self.Screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))
pygame.draw.rect(self.Screen, (black), (175, 75, 200, 100), 2)

def drawPane5(self, textToDisplay):
self.Screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))

self.Screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))
pygame.draw.rect(self.Screen, (black), (175, 75, 200, 100), 2)

def drawPane8(self, textToDisplay):
self.Screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))
pygame.draw.rect(self.Screen, (black), (175, 75, 200, 100), 2)

def drawPane9(self, textToDisplay):
self.Screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))
pygame.draw.rect(self.Screen, (black), (175, 75, 200, 100), 2)

class Screen():

def __init__(self):
pygame.init()
self.font = pygame.font.SysFont('Arial', 25)
pygame.display.set_caption('Box Test')
self.screen = pygame.display.set_mode((1000,600), 0, 32)
self.screen.fill((white))
pygame.display.update()
numberOfPanes = 0
self.NoOfPanes = numberOfPanes

def addPane(self, textToDisplay):
myPane = Pane()
myPane.drawPane(textToDisplay)

def clearScreen(self):
self.screen = pygame.display.set_mode((600,400), 0, 32)
self.screen.fill((white))
pygame.display.update()

def mousePosition(self):
global clickPos
global releasePos
for event in pygame.event.get():
if event.type == MAIN_BUTTON:
self.Pos = pygame.mouse.get_pos()
return MAIN_BUTTON
else:
return False

if __name__ == '__main__':
Pan3 = Screen()
Pan3.addPane("hello")
Pan3.mousePosition()
pygame.display.update()
while True:
ev = pygame.event.get()
for event in ev:
if event.type == pygame.MOUSEBUTTONUP:
posx,posy = pygame.mouse.get_pos()
print(posx)
print(posy)

for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit(); sys.exit();

Я пытаюсь отобразить панели из класса Pane() в классе Screen(), но средство отслеживания координат мыши все еще работает
