你好，当我尝试向sqlite插入数据时，会出现一个错误并且按钮是从框架中消失，问题出在这两个函数def fitcher(insertFun):和def insertFun(self)
from tkinter import *
from tkinter import ttk
import sqlite3
class mainGui(ttk.Frame):
def __init__(self):
Frame.__init__(self,background="lightblue")
self.master.title("Family book library")
self.pack(expand=1, fill=BOTH)
toolBar = Frame(self)
self.buttonPicInsert = PhotoImage(file="insert.png")
addbook = ttk.Button(toolBar,image = self.buttonPicInsert,command = self.insertFun)
addbook.pack(side=LEFT)
self.buttonPicAnalyse = PhotoImage(file="analys.png")
analysis = ttk.Button(toolBar, image = self.buttonPicAnalyse,command = self.analysFun)
analysis.pack(side=LEFT)
self.buttonPicSearch = PhotoImage(file="search.png")

答案 0 :(得分：1)
据我所知，你在这里遗漏了很多东西 首先你需要这个功能
new.wait_window()
return (new.varb..etc)
你需要添加这个
new.conn.commit()
new.conn.close()
此函数必须更改缩进，将其从此函数__init__
def insertFun():
你必须使用这个功能来获取数据
textvariable = new.locationGet
例如
new.locationGet = tk.StringVar()
new.locationFiled = ttk.Entry(new, width=90, justify = CENTER,textvariable = new.locationGet)
new.locationFiled.pack()
也改变了推荐只是阅读了这个页面，它非常适合你的问题here
