Question

我是python的新手。我用vb2010编程，但现在是时候尝试新的东西。我希望在鼠标按下事件后5秒后隐藏动作（如在start（）中）。

import pygame
import sys
from pygame.locals import *
from time import gmtime, strftime
import threading
import time
white = (255,255,255)
black = (0,0,0)
blue = (0,0,255)
width = 600
height = 400
channel = '0001'
name = 'Channel 3'
class screen(object):
    def __init__(self):
        pygame.init()
        self.font = pygame.font.SysFont('Arial', 25)
        pygame.display.set_caption('PyTV')
        self.screen = pygame.display.set_mode((width,height), 0, 32)
        self.screen.fill((black))
        pygame.display.update()

    def printData(self):
        self.rect = pygame.draw.rect(self.screen, (blue), (0, 0, width, height - 350), 0)
        self.screen.blit(self.font.render(channel, True, white), (width - 590, 0))
        self.screen.blit(self.font.render(name, True, white), (height - 335, 0))
        self.screen.blit(self.font.render(strftime("%H:%M %d/%m/%Y", gmtime()), True, white), (width - 590, height - 377))
        pygame.display.update()

    def clean(self):
        self.screen.fill((black))
        pygame.display.update()


if __name__ == '__main__':
    def start():
        Pan3.printData()
        time.sleep(5)
        Pan3.clean()
    Pan3 = screen()
    threading.Thread(target=start).start()
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit(); sys.exit();
            if event.type == pygame.MOUSEBUTTONDOWN:
                print 'Event! Mouse Down! Code here....'

Answer 1

考虑到您也使用线程，timer可能符合您的需求。

编辑：满足您对如何使其工作的更详细解释的需求，这里有一些伪代码。

if event.type == pygame.MOUSEBUTTONDOWN:
    if active_timer:
        timer.cancel()
    timer = Timer(5.0, show_info_things)
    timer.start()

我希望这能让你顺利进行。

当您第一次点击left mouse时，它会显示日期，当您第二次点击时，它会隐藏日期。如果您没有第二次点击，则会在5秒后自动隐藏。

与密钥SPACE相同 - 首先按显示，第二次隐藏。如果你不按第二次，它会在5秒后自动隐藏。

键ESC和right click也会隐藏。

    Screen().run()

在mousedown操作后5秒后隐藏部分
