#win
win = Tk()
win.title("文本编辑")
win.geometry("750x600")
#Menu
m = Menu(win)
win.config(menu=m)
filemenu = Menu(m, tearoff=0)
m.add_cascade(label="文件", menu=filemenu)
filemenu.add_command(label="新建", command=savef)
filemenu.add_command(label="打开", command=openf)
filemenu.add_command(label="保存", command=savef)
#text
t=Text(win)
t.pack(side=RIGHT, fill=BOTH)
#treeview
tr = ttk.Treeview(win)
tr.column("#0", width=200)
tr.pack(side=LEFT, fill=BOTH)
tr.heading("#0", text="文件列表")
win.mainloop()
