Is there an event handling option to minimize and maximize screen in pygame?

问题

Is there any event handler to minimize or maximize screen like there is to quit screen?

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

Pygame adds pygame.ACTIVEEVENTs to the event queue when the window is minimized/iconified or maximized. You can check if event.gain == 1 and event.state == 6: and if event.gain == 0 and event.state == 6: to see if the window was maximized or minimized. The only problem is that event.gain == 1 and event.state == 6 is also True when the window gains input focus.

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)

If you want to minimize/iconify the window with a key press, you can call pygame.display.iconify().
