python - Lubuntu 终端 Python 桌面快捷方式

Question

所以我正在尝试为我用 python 制作的终端 mp3player 创建桌面快捷方式。我正在使用 Lubuntu。

我的程序是这样的

#!/usr/bin/python
# -*- coding: utf-8 -*-
from __future__ import print_function
import os
import sys
import random
from sys import stdout

from pygame import mixer # Load the required library


class mp3Player(object):
    def __init__(self):
        self.mix = mixer
        self.mix.init()

    def play(self, filelist):
        for root, mp3file in filelist:
            try:
                stdout.write(root + '\n')
                stdout.write("Playing %s\n"%mp3file)

                self.mix.music.load(os.path.join(root, mp3file))
                self.mix.music.play()

                while self.mix.music.get_busy():
                    choice = raw_input("[skip, exit, pause, shuffle]\n")
                    if choice == "skip":
                        break
                    elif choice == "pause":
                        self.mix.music.pause()
                        raw_input("Press enter to continiue.")
                        self.mix.music.unpause()
                    elif choice == "shuffle":
                        random.shuffle(filelist)
                        break
                    elif choice == "exit":
                        raise KeyboardInterrupt
                    else:
                        pass

            except KeyboardInterrupt, e:
                self.mix.music.stop()
                print("User Interrupted")
                sys.exit(0)

            stdout.flush()

class mp3Files(object):
    def __init__(self):
        self.mp3player = mp3Player()
        self.filelist = []

    def search(self):
        for root, dirs, files in os.walk(os.getcwd()):
            for mp3file in files:
                if mp3file.endswith(".mp3"):
                    self.filelist.append((root, mp3file))

        self.mp3player.play(self.filelist)

def main():
    mp3 = mp3Files()
    mp3.search()

if __name__ == "__main__":
    main()

您将需要 pygame 来测试它，我建议在您的音乐文件夹中执行它，因为它会递归地在当前目录中搜索 mp3 文件，并在完成后播放列表。但是，这是我的 .desktop 文件。

[Desktop Entry]

当我双击它时，它只打开一个终端而不执行脚本。我究竟做错了什么？哦

提前致谢。

编辑:

文件是可执行的，我执行了

 sudo update-desktop-database

收到警告

终于找到了我所缺少的。

必须首先使用脚本作为命令参数启动 lxterminal。

Exec=lxterminal --command="/home/jan/Schreibtisch/mp3playa/mp3playa"
