的Python 3 Tkinter的樹狀獲得所選項目

的名稱，以便基本上我有this樹：的Python 3 Tkinter的樹狀獲得所選項目

而且我希望有按「爲Aggiungi」按鈕，選擇回項目的名稱。例如，當我選擇番茄，然後按下按鈕我想要「番茄鍾」作爲字符串，如果我選擇Frutta我想要「Frutta」等... 我試着用get.children，然後tree.set（）但我不能讓它工作。我該怎麼做？

from tkinter import * 
from tkinter import ttk 

_root = Tk() 
_root.resizable(width=FALSE, height=FALSE) 

_F_shopItems = Frame(_root) 
_F_shopItems.pack(side="left")

_F_treeview.pack(side="left")

_F_bottom.pack(side="bottom")

虛擬事件和方法可能是你需要什麼，

import tkinter as tk 
from tkinter import ttk 

class Frame(ttk.Frame): 
    def __init__(self, *args, **kw): 
     ttk.Frame.__init__(self, *args, **kw) 
     self.tree = ttk.Treeview(self) 
     self.tree.pack() 

     for i in range(10): 
      self.tree.insert("", tk.END, text="item %s" % i) 

     self.tree.bind('<<TreeviewSelect>>', self.on_select) 

     self.button = ttk.Button(self, text="test", command=self.print_selected) 

     self.button.pack() 
     self.selected = [] 

    def on_select(self, event): 
     self.selected = event.widget.selection() 

    def print_selected(self): 
     for idx in self.selected: 
      print(self.tree.item(idx)['text']) 

if __name__ == "__main__": 
    root = tk.Tk() 
    frame = Frame(root) 
    frame.pack() 
    root.mainloop()
