Tkinter是Python的标准GUI库，可以用来创建各种弹窗。以下是几种常见弹窗的实现方法：
1. 基础消息弹窗文章源自网吧系统维护-https://www.58pxe.com/12845.html
import tkinter as tk from tkinter import messagebox # 创建主窗口 root = tk.Tk() root.withdraw() # 隐藏主窗口 # 信息弹窗 messagebox.showinfo("标题", "这是一条信息") # 警告弹窗 messagebox.showwarning("警告", "这是一个警告") # 错误弹窗 messagebox.showerror("错误", "这是一个错误") # 询问弹窗 result = messagebox.askquestion("问题", "你确定吗？") if result == 'yes': print("用户选择了是") else: print("用户选择了否")
2. 自定义弹窗窗口文章源自网吧系统维护-https://www.58pxe.com/12845.html
import tkinter as tk
def create_popup():
# 创建弹窗窗口
popup = tk.Toplevel()
popup.title("自定义弹窗")
popup.geometry("300x200")
# 添加内容
label = tk.Label(popup, text="这是一个自定义弹窗")
label.pack(pady=20)
button = tk.Button(popup, text="关闭", command=popup.destroy)
button.pack(pady=10)
# 主窗口
root = tk.Tk()
root.title("主窗口")
# 按钮用于触发弹窗
open_button = tk.Button(root, text="打开弹窗", command=create_popup)
open_button.pack(pady=50)
root.mainloop()
3. 模态弹窗（阻止主窗口操作）文章源自网吧系统维护-https://www.58pxe.com/12845.html
import tkinter as tk
def create_modal_popup():
popup = tk.Toplevel()
popup.title("模态弹窗")
popup.geometry("250x150")
# 使弹窗成为模态窗口
popup.transient(root) # 关联到主窗口
popup.grab_set() # 捕获所有事件
label = tk.Label(popup, text="这是模态弹窗")
label.pack(pady=20)
def close_popup():
popup.grab_release() # 释放事件捕获
popup.destroy()
button = tk.Button(popup, text="关闭", command=close_popup)
button.pack(pady=10)
root = tk.Tk()
root.title("主窗口")
modal_button = tk.Button(root, text="打开模态弹窗", command=create_modal_popup)
modal_button.pack(pady=50)
root.mainloop()
4. 带输入框的弹窗文章源自网吧系统维护-https://www.58pxe.com/12845.html
import tkinter as tk
def get_input():
def return_input():
nonlocal user_input
user_input = entry.get()
popup.destroy()
user_input = None
popup = tk.Toplevel()
popup.title("输入弹窗")
popup.geometry("300x150")
label = tk.Label(popup, text="请输入内容:")
label.pack(pady=10)
entry = tk.Entry(popup, width=30)
entry.pack(pady=10)
submit_btn = tk.Button(popup, text="提交", command=return_input)
submit_btn.pack(pady=10)
# 等待弹窗关闭
popup.wait_window()
return user_input
root = tk.Tk()
root.title("主窗口")
input_button = tk.Button(root, text="获取输入", command=lambda: print(get_input()))
input_button.pack(pady=50)
root.mainloop()
5. 进度弹窗文章源自网吧系统维护-https://www.58pxe.com/12845.html
import tkinter as tk
from tkinter import ttk
import time
import threading
def long_running_task(progress_bar, popup):
for i in range(101):
time.sleep(0.05) # 模拟耗时操作
progress_bar['value'] = i
progress_bar.update()
time.sleep(1)
popup.destroy()
def show_progress():
popup = tk.Toplevel()
popup.title("进度")
popup.geometry("300x100")
label = tk.Label(popup, text="处理中，请稍候...")
label.pack(pady=5)
progress_bar = ttk.Progressbar(popup, orient="horizontal", length=250, mode="determinate")
progress_bar.pack(pady=10)
# 在新线程中运行任务
thread = threading.Thread(target=long_running_task, args=(progress_bar, popup))
thread.start()
root = tk.Tk()
root.title("主窗口")
progress_button = tk.Button(root, text="显示进度", command=show_progress)
progress_button.pack(pady=50)
root.mainloop()
