#1.文本框
#lal=tk.Label(root,text="欢迎使用音乐播放器")     
#lal.place(x=80,y=30,width=140,height=15)  


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

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
condition = tk.StringVar()
condition.set("暂停")

b1=tk.Button(root,textvariable=condition,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)

value.set("0")
Scale(root,from_=0,to=100,orient=HORIZONTAL,length=480,show=0,variable=value,resolution=0.01,command=slide).pack()

#-----------------------------------七、定义音乐列表----------------------------------------------


#1.界面-------------------------
scrollbar1 = Scrollbar(root)
scrollbar1.pack(side=RIGHT, fill=Y)
 
listbox1 = Listbox(root,height=20,width=22)
listbox1["yscrollcommand"] = scrollbar1.set

listbox1.pack(side=RIGHT)
scrollbar1["command"] = listbox1.yview

#2.功能--------------------------

def Select(event):
    global Number
    songname=listbox1.get(listbox1.curselection())   
    Number=int(songname.split(".")[0])-1
    print(Number)

    pygame.mixer.music.play(0)
    entry_var.set(SongName[Number])

def  listbox_Show():
    num=1    
    for i in SongName:
        Num=str(num)+"."
        listbox1.insert(END,Num+i)
        num+=1 



listbox1.bind('',Select)
listbox_Show()

#------------------------------------------------------------------

#1.初始播放------------------------------
def init_play():
    pygame.mixer.init()
    pygame.mixer.music.load(SongPath[Number])  
    pygame.mixer.music.play(0)
    play_model()

init_play()
#--------------线程区--------------------------

#播放模式
t1=Play_Model()
t1.start()

#2.播放进度条
t2=Music_PlaySlide()
t2.start()

#3.界面主线程
root.mainloop()
#---------------------------------------
pygame.mixer.music.stop()
