Tkinter列表框與條目

Question

有沒有辦法讓Tkinter列表框的項目成爲條目窗口小部件？結果將是您可以動態修改Listbox條目中的文本。如果你的列表框的樣子：

-------- 
| Apples | 
| Pears | 
| Oranges | 
--------- 

那麼你會希望能夠點擊蘋果和寫一些任意的文本 - 那麼你可以綁定Enter鍵，比方說，觸發基於新文本的功能。

Answer 1

，你可以給用戶一些條目然後創建從輸入

一個列表框，但你不能只改變一個列表框的文字一樣，

也許嘗試不同的GUI庫像WX

編輯

這裏是你可以做的：

from Tkinter import * 


root = Tk() 
opt_list = ['opt1','opt2','opt3','opt4','opt5'] 
sel_list = [] 

def get_sel(): 
    sel_list.append(Lb1.curselection()) 
    root.destroy() 

def change_opt(): 
    entry = E.get() 
    change = entry.split(" ") 
    print change 
    Lb1.insert(int(change[0]),change[1]) 
    root.update() 


def cancel(): 
    root.destroy() 
E = Entry(root) 
A = Button(root, text ="Change", command = change_opt) 
B = Button(root, text ="Submit", command = get_sel) 
C = Button(root, text ="Cancel", command = cancel) 
Lb1 = Listbox(root, selectmode=MULTIPLE) 


for i,j in enumerate(opt_list): 
    Lb1.insert(i,j) 


Lb1.pack() 
B.pack() 
C.pack() 
E.pack() 
A.pack() 

root.mainloop() 

這將使一個列表框與opt_list選項然後當你鍵入比如5 hello的項目，然後按更改將選項hello添加到第五位

那唯一的辦法我能想到的

Answer 2

不，tkinter不支持就地編輯列表框中的項目。當然，如果你真的不需要一個列表框，你總是可以將標籤或輸入小部件堆疊在一起，以獲得相似的效果。

Answer 3

我知道這個問題已經有一段時間了，但我已經創建了一個名爲'ListboxEditable'的小部件，它可以充當列表框，並且當雙擊某個項目時，用戶可以在條目中鍵入任何內容。然後，當用戶單擊另一行時，信息將保存在相應的修改單元格中。請注意，用戶可以使用向上和向下鍵瀏覽整個給定列表（所選行具有不同的背景顏色）。

此代碼是根據Bryan Oakley的回答開發的。

我離開這裏最小的工作情況：

# Imports 
from tkinter import * 
from tkinter.ttk import * 
# Import for the listboxEditable 
from ListboxEditable import * 

# Colors 
colorActiveTab="#CCCCCC" # Color of the active tab 
colorNoActiveTab="#EBEBEB" # Color of the no active tab 
# Fonts 
fontLabels='Calibri' 
sizeLabels2=13 

# Main window 
root = Tk() 

# *** Design ***** 
frame_name=Frame(root,bg=colorActiveTab) # Column frame 
frame_name_label=Frame(frame_name,bg='blue') # Label frame 
label_name=Label(frame_name_label, text="Header", bg='blue', fg='white', font=(fontLabels, sizeLabels2, 'bold'), pady=2, padx=2, width=10) 
frame_name_listbox=Frame(frame_name,bg='blue') # Label frame 
list_name=['test1','test2','test3'] 
listBox_name=ListboxEditable(frame_name_listbox,list_name) 

# *** Packing **** 
frame_name.pack(side=LEFT,fill=Y) 
frame_name_label.pack(side=TOP, fill=X) 
label_name.pack(side=LEFT,fill=X) 
frame_name_listbox.pack(side=TOP, fill=X) 
listBox_name.placeListBoxEditable() 

# Infinite loop 
root.mainloop() 

的ListboxEditable類如下：
