pygame的屏幕没有显示出来

Question

所以我使用pygame的制作基本的天气应用程序，并具有与GUI问题IM

所以所有的代码工作正常，但窗口犯规正确显示

这里是代码：

import ast, sys 
import pygame 
from pygame.locals import * 
import inputbox 
import get_info 

class Weather(): 
    def __init__(self): 
     self.zip = '99354' 
     self.get_info() 
     pygame.font.init() 
     self.state = 2 
     self.font = pygame.font.Font("resources\Sansation_Light.ttf", 16) 
     self.font_render() 
     self.bg = pygame.image.load('resources/background.png') 

     self.refresh = pygame.image.load('resources/button1.png') 
     self.refresh_r = self.refresh.get_bounding_rect() 
     self.refresh_r.x, self.refresh_r.y = (155,550) 
     self.chg_zip = pygame.image.load('resources/button2.png') 
     self.chg_zip_r = self.chg_zip.get_bounding_rect() 
     self.chg_zip_r.x, self.chg_zip_r.y = (20,135) 

     self.main() 

    def font_render(self): 
     self.current_img = pygame.image.load('resources/%s.png'%self.weather) 
     self.cur_temp = self.font.render(self.temp, 0, (255,255,255)) 
     self.cur_weather = self.font.render(self.weather, 0, (255,255,255)) 
     self.updated = self.font.render(self.update[0], 0, (255,255,255)) 
     self.updated2 = self.font.render(self.update[2], 0, (255,255,255)) 
     self.ref_text = self.font.render("Refresh", 0, (255,255,255)) 
     self.zip_text = self.font.render("Change Zip", 0, (255,255,255)) 

    def Draw(self): 

     self.screen.blit(self.bg,(0,0)) 
     self.screen.blit(self.refresh,(155,550)) 
     self.screen.blit(self.ref_text,(200,560)) 
     self.screen.blit(self.chg_zip,(20,135)) 
     self.screen.blit(self.zip_text,(40,140)) 
     self.screen.blit(self.radar_img,(12,175)) 
     self.screen.blit(self.updated,(100,500)) 
     self.screen.blit(self.updated2,(175,525)) 
     self.screen.blit(self.current_img,(20,20)) 
     self.screen.blit(self.cur_temp,(150,50)) 
     self.screen.blit(self.cur_weather,(150,70)) 

     row = 25 
     for i in range(0,5): 
      stat_str = str(self.info[0][i][0])+' : '+ str(self.info[0][i][1]) 
      self.cur_stats = self.font.render(stat_str, 0, (255,255,255)) 
      self.screen.blit(self.cur_stats,(275,row)) 
      row+=25 

    def button(self): 
     if self.refresh_r.collidepoint(pygame.mouse.get_pos()) and pygame.mouse.get_pressed()[0]: 
      self.get_info() 
     if self.chg_zip_r.collidepoint(pygame.mouse.get_pos()) and pygame.mouse.get_pressed()[0]: 
      self.state = 1 

    def get_zip(self): 
     self.screen.blit(self.bg,(0,0)) 
     self.zip = inputbox.ask(self.screen,"Zipcode") 
     self.__init__() 
     self.screen.blit(self.bg,(0,0)) 
     self.state = 2 


    def get_info(self): 

     get_info.get_info(self.zip) 
     print "done" 

     with open('info.txt','r') as info: 
      fore_info = info.read() 

     weather = ast.literal_eval(fore_info) 
     current = weather[0] 
     self.info = weather[1] 
     forecast = weather[2] 
     self.place = weather[3] 
     self.update = self.place.strip().split('.') 
     self.temp = current[0] 
     self.weather = current[1] 
     self.radar_img = pygame.image.load('radar.jpg') 

    def main(self): 
     clock = pygame.time.Clock() 
     self.screen = pygame.display.set_mode((475,600)) 
     pygame.display.set_caption('Weather') 

     while True: 
      clock.tick(45) 
      for event in pygame.event.get(): 
       if event.type == QUIT: 
        sys.exit() 
      if self.state == 1: 
       self.get_zip() 
      else: 
       self.Draw() 
       self.button() 


Weather() 

我知道我的代码是非常草率，而不是最好的，但它仍然有效，当我运行它，这是窗口的外观，除了像：

这表明曾经是它的背后，直到你拖到另一个窗口上，或者你MIN和MAX它，然后它说明了什么，我应该

所以我应该如何改变我的代码，以便它弹出，并显示正常

这可能是因为你从来没有打电话pygame.display.flip()
