Python tk 弹出对话框
精选 原创Python tk 弹出对话框
在Python中,你可以使用tkinter
库来创建弹出对话框。tkinter
提供了一个tkinter.messagebox
模块,其中包含了一些用于创建消息框、警告框、错误框等的函数。以下是一个简单的示例,演示如何创建一个简单的弹出对话框:
import tkinter as tk
from tkinter import messagebox
def show_info_dialog():
messagebox.showinfo("Information", "This is an information dialog.")
def show_warning_dialog():
messagebox.showwarning("Warning", "This is a warning dialog.")
def show_error_dialog():
messagebox.showerror("Error", "This is an error dialog.")
def ask_question():
result = messagebox.askquestion("Question", "Do you want to proceed?")
if result == "yes":
print("User clicked 'Yes'")
else:
print("User clicked 'No'")
# 创建主窗口
root = tk.Tk()
root.title("Dialog Example")
# 创建按钮来触发对话框
info_button = tk.Button(root, text="Show Info Dialog", command=show_info_dialog)
info_button.pack(pady=10)
warning_button = tk.Button(root, text="Show Warning Dialog", command=show_warning_dialog)
warning_button.pack(pady=10)
error_button = tk.Button(root, text="Show Error Dialog", command=show_error_dialog)
error_button.pack(pady=10)
question_button = tk.Button(root, text="Ask Question", command=ask_question)
question_button.pack(pady=10)
# 运行主循环
root.mainloop()
在这个例子中,我们使用messagebox.showinfo
、messagebox.showwarning
和messagebox.showerror
来创建不同类型的对话框。messagebox.askquestion
用于创建包含Yes/No按钮的对话框,并根据用户的选择返回相应的结果。这些对话框通常用于显示信息、警告、错误以及询问用户的意见。

山高路远坑深,
大军纵横驰奔,
谁敢横刀立马?
