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



#---------------一、窗口---------------------
root=tk.Tk()        
root.title('音乐播放器')

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()

#---------------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)



#--------------五、下载功能------------------------------


#1.搜索
en3=tk.Entry(root,justify=CENTER,state=NORMAL)                       
en3.place(x=50,y=150,width=80,height=30) 

b1=tk.Button(root,text="搜索",command=Search)
b1.place(x=135,y=150)

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

#2.下载
en4=tk.Entry(root,justify=CENTER,state=NORMAL)                       
en4.place(x=180,y=150,width=30,height=30) 

b1=tk.Button(root,text="下载",command=DownLoad_music)
b1.place(x=220,y=150)
#-------------------------------------------------


txtCon=tk.scrolledtext.ScrolledText(root,wrap=tk.WORD)
