用python制作简易的音乐播放器（GUI界面制作+OS文件操作+面向对象+多线程）

#----------------------一、音乐文本读取--------------------

SongPath =[filePath+i for i in SongName]

Number=0
volume=0.3

Switch=True

#----------------------二、功能区--------------------------------------

#-----------------------三、面板区-----------------------------------------    





#---------------一、窗口---------------------
root=tk.Tk()        
root.title('音乐播放器')
root["height"]=150   
root["width"]=300    
root.resizable(0,0)

#1.文本框
lal=tk.Label(root,text="欢迎使用音乐播放器")      #在root中创建标签
lal.place(x=50,y=15,width=200,height=50)  #向root放置标签


#---------------二、显示正在播放的歌曲--------------------------

entry_var = tk.StringVar()
entry_var.set('欢迎使用')
en1=tk.Entry(root,textvariable=entry_var,justify=CENTER,state=NORMAL)                       
en1.place(x=50,y=70,width=200,height=15) 

entry_var1 = tk.StringVar()
entry_var1.set('00:00')
en2=tk.Entry(root,textvariable=entry_var1,justify=CENTER)                       
en2.place(x=10,y=5,width=80,height=15) 


#---------------三、音量调节----------------------------

b3=tk.Button(root,text="+",command=fun4)
b3.place(x=50,y=90)

b3=tk.Button(root,text="-",command=fun5)
b3.place(x=65,y=90)



#---------------四、切换歌曲|暂停播放----------------------------------
#1.上一曲按钮
b1=tk.Button(root,text="上一曲",command=fun1)
b1.place(x=80,y=90)


#2.播放按钮
b1=tk.Button(root,text="播放|暂停",command=fun2)  #定义：按钮名称+按钮功能
b1.place(x=130,y=90)          #定义：按钮大小+按钮位置

#3.下一曲按钮
b3=tk.Button(root,text="下一曲",command=fun3)
b3.place(x=195,y=90)

pygame.mixer.init()
t=Current_time()
t.start()




root.mainloop()
