利用python中的tkinter进行gui设计,结合数据库mysql编写一段代码,要求实现顾客操作系统界面,该界面包括选择列表区:显示部分主要是由标题加表格和勾选框以及滑动条组成,操作有全选/取消全选、提交操作、刷新列表。 订单信息区:这个区域是只读的,只有刷新列表一个功能。 功能区:这个区域实时的显示用户信息并且有若干功能按钮,点击相应的按钮就进入相应的功能模块。 用来实现获取正在营业的店铺菜单功能,点外卖提交订单功能,查询订单功能。

抱歉,由于篇幅较长,无法在这里一一解释并编写代码。以下是大致的思路和部分示例代码,供您参考:
1. 导入模块和连接数据库
```python
import tkinter as tk
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
password="yourpassword",
database="yourdatabase"
)
```
2. 创建主窗口和各个控件
```python
root = tk.Tk()
root.title("顾客操作系统")
root.geometry("800x600")
# 选择列表区
select_frame = tk.Frame(root)
select_frame.pack(side=tk.LEFT, fill=tk.BOTH)
# 订单信息区
order_frame = tk.Frame(root)
order_frame.pack(side=tk.TOP, fill=tk.BOTH)
# 功能区
func_frame = tk.Frame(root)
func_frame.pack(side=tk.RIGHT, fill=tk.BOTH)
# 创建表格
table = tk.ttk.Treeview(select_frame, columns=("name", "price", "num"), show="headings")
table.column("name", width=200, anchor="center")
table.column("price", width=200, anchor="center")
table.column("num", width=200, anchor="center")
table.heading("name", text="菜名")
table.heading("price", text="价格")
table.heading("num", text="数量")
table.pack(side=tk.TOP, fill=tk.BOTH)
# 创建勾选框
select_all = tk.BooleanVar()
select_all.set(False)
select_button = tk.Checkbutton(select_frame, text="全选/取消全选", variable=select_all)
select_button.pack(side=tk.TOP)
# 创建滑动条
scrollbar = tk.ttk.Scrollbar(select_frame, orient=tk.VERTICAL, command=table.yview)
scrollbar.pack(side=tk.RIGHT, fill=tk.Y)
table.configure(yscrollcommand=scrollbar.set)
# 创建提交按钮、刷新按钮
submit_button = tk.Button(select_frame, text="提交操作")
submit_button.pack(side=tk.BOTTOM)
refresh_button = tk.Button(select_frame, text="刷新列表")
refresh_button.pack(side=tk.BOTTOM)
```
3. 查询数据库并在表格中显示数据
```python
mycursor = mydb.cursor()
mycursor.execute("SELECT name, price, num FROM menu")
result = mycursor.fetchall()
for row in result:
table.insert("", tk.END, values=row)
```
4. 实现全选/取消全选功能
```python
def select_all_items():
children = table.get_children()
for child in children:
table.item(child, values=(table.item(child)["values"][0], table.item(child)["values"][1], select_all.get()))
select_all.trace("w", lambda *args: select_all_items())
```
5. 实现提交操作和刷新列表功能
```python
def submit_action():
selected_items = []
children = table.get_children()
for child in children:
if table.item(child)["values"][2] != "":
selected_items.append(table.item(child)["values"])
mycursor = mydb.cursor()
for item in selected_items:
sql = "INSERT INTO orders (name, price, num) VALUES (%s, %s, %s)"
val = (item[0], item[1], item[2])
mycursor.execute(sql, val)
mydb.commit()
select_all.set(False)
refresh_action()
def refresh_action():
table.delete(*table.get_children())
mycursor = mydb.cursor()
mycursor.execute("SELECT name, price, num FROM menu")
result = mycursor.fetchall()
for row in result:
table.insert("", tk.END, values=row)
```
6. 实现订单信息区的刷新功能
```python
def refresh_order():
order_text.delete("1.0", tk.END)
mycursor = mydb.cursor()
mycursor.execute("SELECT name, price, num FROM orders")
result = mycursor.fetchall()
for row in result:
order_text.insert(tk.END, "{0} {1}元 x {2}\n".format(row[0], row[1], row[2]))
```
7. 实现功能区的按钮和功能
```python
def get_menu():
# 获取正在营业的店铺菜单功能
pass
def submit_order():
# 点外卖提交订单功能
pass
def query_order():
# 查询订单功能
pass
menu_button = tk.Button(func_frame, text="获取菜单", command=get_menu)
menu_button.pack(side=tk.TOP)
order_button = tk.Button(func_frame, text="提交订单", command=submit_order)
order_button.pack(side=tk.TOP)
query_button = tk.Button(func_frame, text="查询订单", command=query_order)
query_button.pack(side=tk.TOP)
order_text = tk.Text(order_frame)
order_text.pack(side=tk.TOP)
refresh_order()
```
这只是一个简单的示例,可能需要根据具体需求进行修改。同时,在实际开发中还需要注意安全性和可靠性等方面的问题。
