python记事本，采用tkinter组件，完成菜单栏，上下文菜单，状态栏，快捷键

import tkinter as tk 
import tkinter.scrolledtext as tst

#v = tk.StringVar()
class Application(tk.Frame):
    def __init__(self, master=None):  
        tk.Frame.__init__(self, master)
        self.grid()
        self.createWidgets()     
        self.createMenu()         
        root['menu'] = self.menubar 
        root.bind('<Button-3>', self.f_popup)
        #root.bind('<Button-1>', self.callback)

         # 状态栏
        self.status = tk.StringVar()
        self.status.set('Ln: 1 Col: 1')
        self.lblStatus = tk.Label(self, textvariable=self.status, anchor='c')
        self.lblStatus.grid(row=7, column=0, columnspan=20, sticky = tk.S + tk.E)
        root.bind('<Key>', self.loc)
        root.bind('<Button-1>', self.loc)
        
    def createWidgets(self):             
        self.textEdit = tst.ScrolledText(self, width=80, height=25)
        self.textEdit.grid(row=0, column=0, rowspan=6)
        
        '''
        self.lblState = tk.Label
