Python 3. TTK。如何改變特定細胞的價值？

Question

我有一些問題tkinter/ttk。

所以，我知道如何獲取Treeview.focus，但如何更改此表中特定單元格的值？有什麼建議麼？

import tkinter as tk 
import tkinter.ttk as ttk 

root = tk.Tk() 

tview = ttk.Treeview(root) 
tview["columns"] = ("SLOT_1","SLOT_2") 
tview.column("SLOT_1", width=100) 
tview.column("SLOT_2", width=100) 

tview.heading("#0",text="Column 0",anchor="w") 
tview.heading("SLOT_1", text="Column 1") 
tview.heading("SLOT_2", text="Column 2") 

def add_item(): 
    tview.insert("","end",values=("","bar")) 

def edit_item(): 
    focused = tview.focus() 
    print(tview.item(focused)) 

tview.pack() 

add_item = tk.Button(root,text="Add item",command=add_item) 
add_item.pack(expand=True,fill='both') 

edit_item = tk.Button(root,text="Edit item",command=edit_item) 
edit_item.pack(expand=True,fill='both') 

root.mainloop() 

我使用Python 3.6與tkinter/ttk。

我添加了一個線程，以便程序在等待用戶輸入編輯時不會掛起。您可能需要爲要輸入的編輯添加文本框或多個文本框

import tkinter as tk 
import tkinter.ttk as ttk 
import threading 

root = tk.Tk() 

tview = ttk.Treeview(root) 
tview["columns"] = ("SLOT_1", "SLOT_2") 
tview.column("SLOT_1", width=100) 
tview.column("SLOT_2", width=100) 

tview.heading("#0", text="Column 0", anchor="w") 
tview.heading("SLOT_1", text="Column 1") 
tview.heading("SLOT_2", text="Column 2") 

def test_program_thread(): 
    thread = threading.Thread(None, edit_item, None,(), {}) 
    thread.start() 

def add_item(): 
    tview.insert("", "end", values=("", "bar")) 


def edit_item(): 
    focused = tview.focus() 
    x = input('Enter a Value you want to change') 
    tview.insert("", str(focused)[1:], values=("", str(x))) 
    tview.delete(focused) 

tview.pack() 

add_item = tk.Button(root, text="Add item", command=add_item) 
add_item.pack(expand=True, fill='both') 

edit_item_button = tk.Button(root, text="Edit item", command=test_program_thread) 
edit_item_button.pack(expand=True, fill='both') 

root.mainloop()
