在不使用tk.Button的情况下从tk.Text和tk.Listbox获取用户输入

import tkinter as tk

root = tk.Tk()

text_box = tk.Text(root, height=5, width=30)
text_box.insert(tk.END, "请输入内容...")
text_box.pack()

root.mainloop()

import tkinter as tk

root = tk.Tk()

list_box = tk.Listbox(root, height=5, width=30)
list_box.insert(0, "选项1")
list_box.insert(1, "选项2")
list_box.insert(2, "选项3")
list_box.pack()

root.mainloop()

import tkinter as tk

def get_user_input(event):
    # 从文本框中获取用户输入
    user_input = text_box.get("1.0", tk.END).strip()

    # 从列表框中获取用户选择
    selected_index = list_box.curselection()
    selected_option = list_box.get(selected_index)

    print("用户输入：", user_input)
    print("用户选择：", selected_option)

root = tk.Tk()

text_box = tk.Text(root, height=5, width=30)
text_box.insert(tk.END, "请输入内容...")
text_box.pack()

list_box = tk.Listbox(root, height=5, width=30)
list_box.insert(0, "选项1")
list_box.insert(1, "选项2")
list_box.insert(2, "选项3")
list_box.pack()

root.bind("<Return>", get_user_input)
root.mainloop()
