python - pygame 中是否有事件处理选项来最小化和最大化屏幕？

Question

是否有任何事件处理程序可以最小化或最大化屏幕，就像退出屏幕一样？

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

Answer 1

当窗口最小化/图标化或最大化时，Pygame 将 pygame.ACTIVEEVENT 添加到事件队列中。您可以检查 if event.gain == 1 and event.state == 6: 和 if event.gain == 0 and event.state == 6: 来查看窗口是否最大化或最小化。唯一的问题是，当窗口获得输入焦点时，event.gain == 1 和 event.state == 6 也为 True。

import pygame as pg


pg.init()
screen = pg.display.set_mode((640, 480))
clock = pg.time.Clock()
BG_COLOR = pg.Color('gray12')

done = False
while not done:
    for event in pg.event.get():
        if event.type == pg.QUIT:
            done = True
        elif event.type == pg.KEYDOWN:
            if event.key == pg.K_i:
                pg.display.iconify()
        elif event.type == pg.ACTIVEEVENT:
            if event.gain == 1 and event.state == 6:
                print('maximized')
            elif event.gain == 0 and event.state == 6:
                print('minimized')

    screen.fill(BG_COLOR)
    pg.display.flip()
    clock.tick(60)

如果您想通过按键最小化/图标化窗口，您可以调用pygame.display.iconify() .
