在Tkinter中激活列表框中的输入框

import tkinter as tk

def on_listbox_click(event):
    selected_item = listbox.get(listbox.curselection())
    entry.delete(0, tk.END)
    entry.insert(tk.END, selected_item)

def on_entry_change(event):
    # 更新列表框中的项
    search_text = entry.get()
    listbox.delete(0, tk.END)
    for item in items:
        if search_text.lower() in item.lower():
            listbox.insert(tk.END, item)

root = tk.Tk()

# 创建列表框和输入框
listbox = tk.Listbox(root)
entry = tk.Entry(root)

# 将列表框和输入框放置在窗口中
listbox.pack()
entry.pack()

# 绑定事件
listbox.bind("<Button-1>", on_listbox_click)
entry.bind("<KeyRelease>", on_entry_change)

# 初始数据
items = ["Apple", "Banana", "Cherry", "Durian", "Elderberry"]

# 将初始数据添加到列表框中
for item in items:
    listbox.insert(tk.END, item)

root.mainloop()
