该项目主要功能,图书的增删查改,借阅证的增、删;借阅证用于结借书管理;借阅证分为老师和学生,numbers为借阅状态:
项目使用mysql数据库,表为3张:
先看运行主界面及功能:
主页面实现代码:
initwin(): #主窗口
def __init__(self,master):
global im
global image
self.master=master
self.master.config(bg='Magenta')
self.initwin=tk.Frame(self.master,)
self.initwin.pack()
self.canvas = tk.Canvas(self.initwin,
width = 1000,
height = 700,
bg = 'green')
image=Image.open('bg.jpg')
im=ImageTk.PhotoImage(image)
self.canvas.create_image(0,0,anchor='nw',image = im) # 使用create_image将图片添加到Canvas组件中
self.canvas.pack() # 将Canvas添加到主窗口
btn_add=ttk.Button(self.initwin,text="图书入库或修改信息",command=self.add)
btn_query=ttk.Button(self.initwin,text="查询图书信息",command=self.query)
btn_card=ttk.Button(self.initwin,text="借书证管理",command=self.card)
btn_borrow=ttk.Button(self.initwin,text="借书",command=self.borrow)
btn_return=ttk.Button(self.initwin,text="还书",command=self.returnbook)#return是保留字。。。
self.canvas.create_window(100,50,width=200,height=40,window=btn_add)
self.canvas.create_window(100,100,width=200,height=40,window=btn_query)
self.canvas.create_window(100,250,width=200,height=40,window=btn_card)
self.canvas.create_window(100,150,width=200,height=40,window=btn_borrow)
self.canvas.create_window(100,200,width=200,height=40,window=btn_return)
self.title=tk.Label(self.initwin,text="图书管理系统",font=("宋体",30))
self.author=tk.Label(self.initwin,text="源代码+QQ:3125841747",font=("宋体",24))
self.canvas.create_window(400,150,anchor="nw",width=300,height=70,window=self.title)
self.canvas.create_window(400,350,anchor="nw",window=self.author)
def add(self,): #add窗口,实现的功能:选择批量入库或者单本入库,添加或是修改
self.initwin.destroy()
addwin(self.master)
def query(self):
self.initwin.destroy()
querywin(self.master)
def card(self):
self.initwin.destroy()
cardwin(self.master)
def borrow(self):
self.initwin.destroy()
borrowwin(self.master)
def returnbook(self):
self.initwin.destroy()
returnwin(self.master)
图书入库:分为单本入库和读取记事本批量入库:
单本入库:实现对图书的增、改:
批量入库成功后,会在文件夹中生成日志文件:
入库图书代码实现:
addwin():
def __init__(self,master):
global im
global image
self.master=master
self.master.config(bg='GhostWhite')
self.str="此处输出状态信息"
self.addwin=tk.Frame(self.master,)
self.addwin.pack()
self.canvas = tk.Canvas(self.addwin,

bg = 'white')
image=Image.open('bg.jpg')
im=ImageTk.PhotoImage(image)
self.canvas.create_image(0,0,anchor='nw',image = im) # 使用create_image将图片添加到Canvas组件中
self.canvas.pack() # 将Canvas添加到窗口
self.btn_back=ttk.Button(self.addwin,text="返回主菜单",command=self.back)
#btn_back.pack()
self.canvas.create_window(100,50,width=200,height=40,window=self.btn_back)
self.mode=tk.IntVar() #选择入库模式(单本或者批量)
self.style_radio=ttk.Style()
self.style_radio.configure("radio.TRadiobutton",font=("微软雅黑",12),background="Aqua")

self.state=tk.Message(self.addwin,text=self.str,width=300,font=("微软雅黑",12))
self.canvas.create_window(800,100,height=50,window=self.s_title)
self.canvas.create_window(650,150,anchor="nw",width=300,window=self.state)
self.flag1=0#标记“批量入库”的控件是否存在的flag
self.flag2=0#标记“单本入库”的控件是否存在的flag
self.cflag=0#change flag,用来区分是添加一本书还是修改书的信息.为1时代表修改
查询图书可以分为:类别、书名、出版社、年份、作者、价格这几种进行查询:
按类别查询:
按书名查询:
按出版社查询:
其他功能不一一演示,
查询图书的代码:
ef show(self,result):
#美观方面的问题还需要改进。。。现在先大体实现功能
#重构此部分,由label改为ttk的Treeview
self.query_list=ttk.Treeview(self.querywin,columns=["书号","类别","书名","出版社","年份","作者","价格","库存数"],show="headings")#show设为headings可以隐藏首列

借书需要有借阅证,借阅证添加操作:
拥有借阅的证号,才可以借书:
还书 :
借书代码实现如下:
