使用Python创建一个简单的任务管理器应用程序

import tkinter as tk
from tkinter import ttk

# 创建主窗口
root = tk.Tk()
root.title("任务管理器")

# 创建任务列表框架
task_frame = ttk.LabelFrame(root, text="任务列表")
task_frame.grid(row=0, column=0, padx=10, pady=5, sticky="nsew")

# 创建任务列表
task_list = tk.Listbox(task_frame, height=15, width=50)
task_list.pack(fill="both", expand=True)

# 创建滚动条
scrollbar = ttk.Scrollbar(task_frame, orient="vertical", command=task_list.yview)
scrollbar.pack(side="right", fill="y")

# 绑定滚动条和列表
task_list.config(yscrollcommand=scrollbar.set)

# 创建按钮框架
button_frame = ttk.LabelFrame(root, text="操作")
button_frame.grid(row=1, column=0, padx=10, pady=5, sticky="nsew")

# 创建按钮
add_button = ttk.Button(button_frame, text="添加任务")
edit_button = ttk.Button(button_frame, text="编辑任务")
delete_button = ttk.Button(button_frame, text="删除任务")
complete_button = ttk.Button(button_frame, text="完成任务")

add_button.grid(row=0, column=0, padx=5, pady=3)
edit_button.grid(row=0, column=1, padx=5, pady=3)
delete_button.grid(row=0, column=2, padx=5, pady=3)
complete_button.grid(row=0, column=3, padx=5, pady=3)

# 启动主循环
root.mainloop()

# 添加任务
def add_task():
    task = task_entry.get()
    if task:
        task_list.insert("end", task)
        task_entry.delete(0, "end")

# 编辑任务
def edit_task():
    selected_task = task_list.curselection()
    if selected_task:
        index = selected_task[0]
        task_entry.delete(0, "end")
        task_entry.insert("end", task_list.get(index))
        task_list.delete(index)

# 删除任务
def delete_task():
    selected_task = task_list.curselection()
    if selected_task:
        index = selected_task[0]
        task_list.delete(index)

# 完成任务
def complete_task():
    selected_task = task_list.curselection()
    if selected_task:
        index = selected_task[0]
        task_list.itemconfig(index, {"bg": "light gray"})

# 创建任务输入框
task_entry = ttk.Entry(task_frame, width=50)
task_entry.pack(pady=5)

# 绑定按钮功能
add_button.config(command=add_task)
edit_button.config(command=edit_task)
delete_button.config(command=delete_task)
complete_button.config(command=complete_task)
