Question

我有以下代码。这基本上从文件夹应用程序及其子文件夹中获取所有图像。我的问题是我试图在所有图像上添加一个点击事件来做同样的事情。基本上＆＃34; exec("apps/" + apps[app_count] + "/app.py"）＆＃34;

# -*- coding: utf-8 -*-
from pygame import *
import os
import pygame
import time
import random
import sys

_image_library = {}

class SeedOS():

    def home(self):
        (width, height) = (240, 320)
        screen = pygame.display.set_mode((width, height))
        pygame.display.set_caption('Seed OS')
        pygame.font.init() 
        Font30 = pygame.font.SysFont('Arial', 30)
        WHITE = (255,255,255)
        BLACK = (0,0,0)
        screen.fill(WHITE)
        apps = os.walk("apps").next()[1]
        app_count = 0
        icon_width = 15
        icon_height = 0
        max_width = 155
        pygame.display.flip()
        while True:
            while app_count < len(apps):
                print apps[app_count]
                image = pygame.image.load("apps/" + apps[app_count] + "/app.png").convert()
                screen.blit(image, (icon_width, icon_height))
                icon_width+=70
                if icon_width > max_width:
                    icon_width = 15
                    icon_height +=70
                app_count += 1
            time2 = time.strftime('%H:%M:%S')
            pygame.display.flip()
            pygame.draw.rect(screen,BLACK,(0,290,240,30))
            clock = Font30.render(time2, False, WHITE)
            screen.blit(clock,(60,288))
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    sys.quit()

phone = SeedOS()
phone.home()

这是检查文件夹中所有内容的代码的一部分＆＃34; apps＆＃34;

while app_count < len(apps):
                    print apps[app_count]
                    image = pygame.image.load("apps/" + apps[app_count] + "/app.png").convert()
                    screen.blit(image, (icon_width, icon_height))
                    icon_width+=70
                    if icon_width > max_width:
                        icon_width = 15
                        icon_height +=70
                    app_count += 1

并附加每个文件夹中的所有图像。我希望每次点击图标，执行它＆＃34; app.py＆＃34;在每个应用程序文件夹中都有两个文件：＆＃34; app.png＆＃34;和＆＃34; app.py＆＃34;。

您可以在apps列表中添加每个图片的坐标，然后使用pygame.mouse.get_pos()方法使用这些坐标：

while True:
            while app_count < len(apps):
                print apps[app_count]
                apps[app_count] = (apps[app_count], icon_width, icon_height)  # Adding coordinates to the list
                image = pygame.image.load("apps/" + apps[app_count][0] + "/app.png").convert() # Adding an index to find the image in the tuple
                screen.blit(image, (icon_width, icon_height))
                icon_width+=70
                if icon_width > max_width:
                    icon_width = 15
                    icon_height +=70
                app_count += 1
            time2 = time.strftime('%H:%M:%S')
            pygame.display.flip()
            pygame.draw.rect(screen,BLACK,(0,290,240,30))
            clock = Font30.render(time2, False, WHITE)
            screen.blit(clock,(60,288))
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    sys.quit()
                if event.type == pygame.MOUSEBUTTONDOWN:
                    if event.button == 1: # MOUSEBUTTONLEFT
                        for a in apps:
                            if a[1] < pygame.mouse.get_pos()[0] < a[1]+IMAGEWIDTH and a[2] < pygame.mouse.get_pos()[1] < a[2] + IMAGEHEIGHT:
                                # Instruction to launch ("apps/" + a[0] + "/app.py")

您所要做的就是定义图标的宽度和高度（如果每个应用程序的内容与pygame.Surface.get_size()不一致），并替换最后一行用正确的语法。在Windows上你可以使用：

os.system("apps\\"+a[0]+"\\app.py") # of course you should import os first

如何在Pygame中为图像添加点击事件？
