如何讓插入到tkinter條目小部件中的圖形覆蓋tkinter樹視圖中的默認值

Question

我下面有一些代碼可將在entry小部件中entry圖形插入到從tree1中選擇的名為tree2 tkinter treeview ，以覆蓋默認圖形。 我能切插入month ，但是當我插入figure的下方，選擇treeview的內容，並在column1不column2 。 如果未輸入任何數字，則默認值為2018

感謝您提出的實現建議

from tkinter import ttk
import tkinter as tk


blow = [("january", "2013"),("february", "2014"),("march", "2015"),("april",
"2016"),("may", "2017")]

def append_select():
    cur_id = tree.focus()
    data = 2018
    data = e1_sub.get()  # if none is provided the default should 2018

    if cur_id:
        tree2.insert("", tk.END, values=data)
       #tree2.insert("", tk.END, values=tree2.column("#2")[data])
        tree2.insert("", tk.END, values=tree.item(cur_id)['values'][:1])


root = tk.Tk()
root.geometry("500x500")

tree = ttk.Treeview(columns=("columns1", "columns"), show="headings",
selectmode="browse")
tree.heading("#1", text="Month")
tree.heading("#2", text="Year")

for n in blow:
    tree.insert("", tk.END, values=(n))

tree.pack()

e1_sub = tk.StringVar()
e1 = tk.Entry(root, textvariable=e1_sub)
e1.pack()

b1 = tk.Button(text="append", command=append_select)
b1.pack()

tree2 = ttk.Treeview(columns=("Month", "Year"), show="headings")
tree2.heading("#1", text="First name")
tree2.heading("#2", text="Surname")
tree2.pack()

root.mainloop()

我想您想做的是：

def append_select():
    cur_id = tree.focus()

    data = e1_sub.get()  # if none is provided the default should 2018
    if not data:
        data = 2018

    if cur_id:
        month = tree.item(cur_id)['values'][0]
        tree2.insert("", tk.END, values=(month, data))

基本上，它首先檢查條目是否為空，如果為空，則返回2018，然后簡單地將其寫入。 可能結構更好。
