import tkinter as tk
from tkinter import ttk, filedialog, messagebox# 创建主窗口
root = tk.Tk()
root.title("Tkinter 工具栏示例")
root.geometry("800x600")# 创建文本编辑框
text_editor = tk.Text(root, wrap='word', relief=tk.FLAT)
text_editor.pack(fill=tk.BOTH, expand=True, padx=10, pady=10)# 当前文件路径
current_file = None# 工具栏回调函数
def new_file():global current_filecurrent_file = Nonetext_editor.delete(1.0, tk.END)def open_file():global current_filecurrent_file = filedialog.askopenfilename(defaultextension=".txt",filetypes=[("Text Files", "*.txt"), ("All Files", "*.*")])if current_file:text_editor.delete(1.0, tk.END)with open(current_file, "r", encoding="utf-8") as file:text_editor.insert(1.0, file.read())def save_file():global current_fileif current_file:with open(current_file, "w", encoding="utf-8") as file:file.write(text_editor.get(1.0, tk.END))else:save_as_file()def save_as_file():global current_filecurrent_file = filedialog.asksaveasfilename(defaultextension=".txt",filetypes=[("Text Files", "*.txt"), ("All Files", "*.*")])if current_file:with open(current_file, "w", encoding="utf-8") as file:file.write(text_editor.get(1.0, tk.END))def cut_text():text_editor.event_generate("<<Cut>>")def copy_text():text_editor.event_generate("<<Copy>>")def paste_text():text_editor.event_generate("<<Paste>>")# 创建工具栏
toolbar = ttk.Frame(root)
toolbar.pack(side=tk.TOP, fill=tk.X)# 添加工具栏按钮
new_button = ttk.Button(toolbar, text="新建", command=new_file)

paste_button.pack(side=tk.LEFT, padx=2, pady=2)# 运行主循环
root.mainloop()
