2.動態Label標簽

使用 textvariable 參數，set 設定動態標簽內容 def label(self):self.playingsong = StringVar()self.playingsong.set('暫無播放歌曲')self.playinglabel = tkinter.Label(self.window, width='45', bg='#87CEEB', textvariable=self.playingsong)self.playinglabel.grid(row=1, column=0, columnspan=5)

3.歌單列表ListBox

根據選擇的目錄獲取到具體歌曲信息，插入到listbox中 def listbox(self):self.songlistbox = tkinter.Listbox(self.window, width=45, height=12, selectmode='single')self.songlistbox.grid(row=2, column=0, columnspan=5)yscrollbar = tkinter.Scrollbar(self.window, command=self.songlistbox.yview)yscrollbar.place(x=306, y=65, height=217, anchor='nw')self.songlistbox.config(yscrollcommand=yscrollbar.set)
