写一个管理系统图标的程序

这个任务可以使用 Python 的 tkinter 模块来完成。以下是一个简单的示例程序，可以用于添加、编辑和删除图标。

import tkinter as tk
from tkinter import filedialog
from PIL import Image, ImageTk

class IconManager:
    def __init__(self, master):
        self.master = master
        self.icons = {}
        self.current_icon = None
        self.create_widgets()

    def create_widgets(self):
        self.icon_listbox = tk.Listbox(self.master)
        self.icon_listbox.pack(side=tk.LEFT, fill=tk.BOTH, expand=True)
        self.icon_listbox.bind('<<ListboxSelect>>', self.select_icon)

        self.add_button = tk.Button(self.master, text='Add', command=self.add_icon)
        self.add_button.pack()

        self.edit_button = tk.Button(self.master, text='Edit', command=self.edit_icon, state=tk.DISABLED)
        self.edit_button.pack()

        self.delete_button = tk.Button(self.master, text='Delete', command=self.delete_icon, state=tk.DISABLED)
        self.delete_button.pack()

        self.preview_label = tk.Label(self.master)
        self.preview_label.pack(side=tk.RIGHT, fill=tk.BOTH, expand=True)

    def add_icon(self):
        filetypes = [('Image Files', ('.png', '.jpg', '.jpeg', '.gif')), ('All Files', '*.*')]
        filename = filedialog.askopenfilename(filetypes=filetypes)
        if filename:
            icon_image = Image.open(filename)
            icon_name = filename.split('/')[-1]
            self.icons[icon_name] = icon_image
            self.icon_listbox.insert(tk.END, icon_name)
            self.select_icon(None)

    def edit_icon(self):
        filename = filedialog.asksaveasfilename(defaultextension='.png')
        if filename:
            self.current_icon.save(filename)

    def delete_icon(self):
        if self.current_icon:
            icon_name = self.icon_listbox.get(self.icon_listbox.curselection())
            self.icon_listbox.delete(self.icon_listbox.curselection())
            del self.icons[icon_name]
            self.select_icon(None)

    def select_icon(self, event):
        if self.icon_listbox.curselection():
            icon_name = self.icon_listbox.get(self.icon_listbox.curselection())
            self.current_icon = self.icons[icon_name]
            icon_image = ImageTk.PhotoImage(self.current_icon)
            self.preview_label.config(image=icon_image)
            self.preview_label.image = icon_image
            self.edit_button.config(state=tk.NORMAL)
            self.delete_button.config(state=tk.NORMAL)
        else:
            self.current_icon = None
            self.preview_label.config(image='')
            self.edit_button.config(state=tk.DISABLED)
            self.delete_button.config(state=tk.DISABLED)

if __name__ == '__main__':
    root = tk.Tk()
    root.title('Icon Manager')
    icon_manager = IconManager(root)
    root.mainloop()

这个程序创建了一个窗口，其中包含一个列表框，用于显示所有图标的名称，并将选定的图标显示在右侧的标签中。可以使用“添加”按钮添加新图标，使用“编辑”按钮编辑当前选定的图标，并使用“删除”按钮删除当前选定的图标。
