通过词典连接两个组合（目的是在Combobox中显示男性或女性名称）

Question

我有一个组合，可以选择性别男性或女性。然后，我还有另一个Combobox，现在所有人的名字都被显示（没有性别的区别）。

我想从第一个Combobox中选择雄性，然后自动显示（无按钮）第二个Combobox中的男性名称。女性名字同样的事情。谢谢

from tkinter import ttk
import tkinter as tk
from tkinter import *

window = tk.Tk()  
window.attributes('-zoomed', True)
window.configure(bg='#f3f2f2')

style = ttk.Style(window)
style.theme_use('clam')

John = {"Name": "John", "Years": 1980, "Gender": "Male"}
Linda = {"Name": "Linda", "Years": 1983, "Gender": "Female"}
Martin = {"Name": "Martin", "Years": 1981, "Gender": "Male"}


gender=ttk.Combobox(window, width = 12)
gender.place(x=5, y=60)
gender['value'] = ["Male", "Female"]
gender.set("Gender?")

all_name=ttk.Combobox(window, width = 12)
all_name.place(x=150, y=60)
all_name['value'] = [x["Name"] for x in [John, Linda, Martin]]
all_name.set("All Name")



window.mainloop()

Answer 1

您可以绑定＆lt;＆lt; comboboxSelected＆gt;＆gt;在性别上的事件和更新 value value all_name ofert all_name 事件回调：

...
def on_gender_selected(event):
    selected = gender.get()
    # get the names for selected gender
    all_name['value'] = [x['Name'] for x in [John, Linda, Martin] if x['Gender'] == selected]
    all_name.set('') # clear current selection

gender.bind('<<ComboboxSelected>>', on_gender_selected)
...
