Question

我试图在tkinter python中创建一个设置窗口，我试图为所有组合框创建相同的回调函数，但是我不知道如何识别哪个组合框是调用方。示例代码：

def Open_settings_Form():
    def callbackFunc(event):
        print(event.widget.current())

    global SETTINGS
    Settings_Form = Toplevel(Main_Form)
    Settings_Form.title("LOG Settings")
    Settings_Form.geometry('900x300')  

    labelTop = Label(Settings_Form, text = "Log Parsing Order")
    labelTop.grid(column=0, row=0)

    combo0 = ttk.Combobox(Settings_Form, state="readonly", values=Log_Fields)
    combo0.bind("<<ComboboxSelected>>", callbackFunc)
    combo0.current(SETTINGS['LOG_Order'][0])
    combo0.grid(column=0, row=1)
    combo1 = ttk.Combobox(Settings_Form, state="readonly", values=Log_Fields)
    combo1.bind("<<ComboboxSelected>>", callbackFunc)
    combo1.current(SETTINGS['LOG_Order'][1])
    combo1.grid(column=1, row=1)
    combo2 = ttk.Combobox(Settings_Form, state="readonly", values=Log_Fields)
    combo2.bind("<<ComboboxSelected>>", callbackFunc)
    combo2.current(SETTINGS['LOG_Order'][2])
    combo2.grid(column=2, row=1)
    combo3 = ttk.Combobox(Settings_Form, state="readonly", values=Log_Fields)
    combo3.bind("<<ComboboxSelected>>", callbackFunc)
    combo3.current(SETTINGS['LOG_Order'][3])
    combo3.grid(column=3, row=1)

在我的callbackFunc中，我可以获取组合框的选定项，但无法找到触发该事件的组合框。除了正在使用的 ComboboxSelected 以外，还有其他绑定方法吗？以下是event.widget对象的方法/参数：

非常感谢

您可以将名称传递给combobox小部件，然后通过event.widget回调对其进行检索。

import tkinter as tk
from tkinter import ttk

root = tk.Tk()

def details(event):
    print (event.widget)

combo1 = ttk.Combobox(root,name="box1")
combo1["values"] = ("A","B","C")
combo1.pack()
combo1.bind("<<ComboboxSelected>>",details)

combo2 = ttk.Combobox(root,name="box2")
combo2["values"] = ("D","E","F")
combo2.pack()
combo2.bind("<<ComboboxSelected>>",details)

root.mainloop()

从绑定事件中检索Tkinter中的组合框名称
