进入全屏时屏幕大小不更新

Question

进入全屏时，窗口进入全屏，但颜色不进入。我试过检查它是否在全屏，并用RESIZE属性刷新，但这只适用于在全屏之外调整大小的情况。代码：

import time
import ctypes, pygame
from Game import Character
from pygame.locals import (
    K_UP,
    K_DOWN,
    K_LEFT,
    K_RIGHT,
    K_ESCAPE,
    K_F11,
    KEYDOWN,
    QUIT
)
print("Starting")

global active
global screen

user32 = ctypes.windll.user32
SCREEN_WIDTH = int(round(user32.GetSystemMetrics(0) / 2, 0))
SCREEN_HEIGHT = int(round(user32.GetSystemMetrics(1) / 2, 0))

timeOne = time.time()

pygame.init()

def Main():
    active = True
    screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT), pygame.RESIZABLE)
    pygame.display.set_caption("Test")

    print("Done. Complete in ", round(time.time()-timeOne, 2), "seconds.")

    while active:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                active = False
            elif event.type == KEYDOWN:
                if event.key == K_ESCAPE:
                    active = False
                elif event.key == K_F11:
                    if screen.get_flags() & pygame.FULLSCREEN:
                        pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
                    else:
                        pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT), pygame.FULLSCREEN)
            elif event.type == pygame.VIDEORESIZE:
                screenSize = event.size
                screen = pygame.display.set_mode(screenSize, pygame.RESIZABLE)

        screen.fill((0, 0, 255))
        pygame.display.flip()

    pygame.quit()

Main()

这是我第一次参加pygame，所以要为任何新手的错误提前道歉

我使用的代码决定了显示器打开窗口时的屏幕尺寸↔ 全屏。我不认为VIDEORESIZE事件是在开关中触发的，因为视频大小实际上没有改变（也许有办法触发它，但我认为不同的全屏和窗口大小有点历史遗留）

这样做的结果是，在切换过程中，显示屏必须重新初始化。下面的程序将在窗口和窗口之间切换↔ F11上的全屏模式，将整个屏幕涂成蓝色。互联网上有一些关于这种切换技术的老代码片段和评论，还有鼠标操作等方面的变化。我发现这些已经不再必要了。。。至少在我的测试系统上(如果需要进一步了解，请告知我们。）

import pygame

        WINDOW_WIDTH  = new_width
        WINDOW_HEIGHT = new_height
        #pygame.key.set_mods( 0 ) #HACK: work-a-round for a SDL bug??

    # Update the window, but not more than 60fps
    window.fill( SKY_BLUE )
    pygame.display.flip()

    # Clamp FPS
    clock.tick_busy_loop(60)

    # Failsafe - exit after 15 seconds (in case your display goes sqrilly)
    if ( pygame.time.get_ticks() > 15000 ):
        print("Exiting Failsafe")
        break

pygame.quit()
