Tkinterのウィジェット一覧をリストで取得する

Posted at

TkinterでGUIを作成するときに配置したウィジェットを一覧で取得する必要があったのでメモ。

import tkinter as tk

# ウィジェット一覧をリストで取得
def get_all_widget (wid, finList=None) -> list:
    if finList is None:
        finList = []
    _list = wid.winfo_children()        
    for item in _list :
        finList.append(item)
        get_all_widget(item,finList)   
    return finList

root = tk.Tk()

# ~~~~~~~~~~
# ウィジェット配置処理は割愛。
# ~~~~~~~~~~

for wdg in get_all_widget(root):
    print(wdg)

結果

直下だけでなくcanvasの中のwidgetも取得する。
