Скрытие столбцов TreeView в Tkinter

Question

Я создал TreeView, но я хочу, чтобы иметь возможность скрывать определенные столбцы при вызове определенных функций. Таким образом, этот TreeView сначала создается, но когда я вызываю функцию, можно сказать, что все столбцы скрыты, за исключением [trackArtist]. Как мне это сделать? Я могу заставить его работать, переписав части TreeView (столбцы, которые я хочу появиться) внутри функции, но это кажется ужасно избыточным.

def some_function(self): 
     self.tree = ttk.Treeview(self.stationBuilderMenuMiddleFrame) 
     ttk.Style().configure("displayField", background="#850664", foreground="#000000", fieldbackground="#FFFFFF") 
     ysb = ttk.Scrollbar(self.stationBuilderMenu, orient=tk.VERTICAL, command=self.tree.yview) 
     xsb = ttk.Scrollbar(self.stationBuilderMenu, orient=tk.HORIZONTAL, command=self.tree.xview) 
     self.tree.configure(yscrollcommand=ysb.set) 
     self.tree.configure(xscrollcommand=xsb.set) 

     self.tree["columns"]=("trackNumber", "trackTitle", "artistCat", "artistDisplay", "trackArtist", "album", 
           "albumLabel", "composer", "year", "trackDuration", "albumAsin", "albumItunes", "ISRC", 
           "filename", "albumCoverName", "notes") 
     self.tree.column("trackNumber", stretch=0, anchor=N) 
     self.tree.column("trackTitle", stretch=0, anchor=N) 
     self.tree.column("artistCat", stretch=0, anchor=N) 
     self.tree.column("artistDisplay", stretch=0, anchor=N) 
     self.tree.column("trackArtist", stretch=0, anchor=N) 
     self.tree.column("album", stretch=0, anchor=N) 
     self.tree.column("albumLabel", stretch=0, anchor=N) 
     self.tree.column("composer", stretch=0, anchor=N) 
     self.tree.column("year", stretch=0, anchor=N) 
     self.tree.column("trackDuration", stretch=0, anchor=N) 
     self.tree.column("albumAsin", stretch=0, anchor=N) 
     self.tree.column("albumItunes", stretch=0, anchor=N) 
     self.tree.column("filename", stretch=0, anchor=N) 
     self.tree.column("albumCoverName", stretch=0, anchor=N) 
     self.tree.column("notes", stretch=0, anchor=N) 
     self.tree.heading("trackNumber", text="Track Number") 
     self.tree.heading("trackTitle", text="Track Title") 
     self.tree.heading("artistCat", text="Artist CAT") 
     self.tree.heading("artistDisplay", text="Artist Display") 
     self.tree.heading("trackArtist", text="Track Artist") 
     self.tree.heading("album", text="Album") 
     self.tree.heading("albumLabel", text="Album Label") 
     self.tree.heading("composer", text="Composer") 
     self.tree.heading("year", text="Year") 
     self.tree.heading("trackDuration", text="Track Duration") 
     self.tree.heading("albumAsin", text="Album ASIN") 
     self.tree.heading("albumItunes", text="Album iTunes") 
     self.tree.heading("ISRC", text="ISRC") 
     self.tree.heading("filename", text="File Name") 
     self.tree.heading("albumCoverName", text="Album Cover Filename") 
     self.tree.heading("notes", text="Notes") 
     self.tree.grid(in_=self.stationBuilderMenuMiddleFrame, row=0, column=0, sticky=tk.NSEW) 
     ysb.grid(in_=self.stationBuilderMenuMiddleFrame, row=0, column=1, sticky=tk.NS) 
     xsb.grid(in_=self.stationBuilderMenuMiddleFrame, row=1, column=0, sticky=tk.EW) 
     self.stationBuilderMenuMiddleFrame.rowconfigure(0, weight=1) 
     self.stationBuilderMenuMiddleFrame.columnconfigure(0, weight=1) 

Это код взлома, который я выбрал вместе. Не работает очень хорошо.

Вы должны быть в состоянии сделать это, используя

self.tree["displaycolumns"]=("artistCat", "artistDisplay")

Найдено на Documentation.

Чтобы отобразить все, кроме одного, вы можете построить его в цикле

exclusionlist=[...] 
displaycolumns=[] 
for col in tree["columns"]: 
    if not "%s"%col in exclusionlist: 
     displaycolumns.append(col) 
tree["displaycolumns"]=displaycolumns 

Найти ниже рабочего кода, который не портил данные. ТОЛЬКО С ПОМОЩЬЮ tree["displaycolumns"]=[...]
