hi,
i make little rewrite your LabEntry.
seems to work
<code>
import tkinter as Tk
class LabEntry(Tk.Frame) :
def __init__(self,root,label,**args) :
super().__init__()
entry = Tk.Entry(self, **args)
entry.grid(column=1, row=0)
Lab=Tk.Label(self,text=label)
Lab.grid(column=0,row=0)
def Finish() :
root.destroy()
root= Tk.Tk()
root.protocol('WM_DELETE_WINDOW',Finish)
Name= Tk.StringVar()
Name.set('')
NameE= LabEntry(root,'Name :',textvariable=Name,width=25)
NameE.grid(column=0,row=0)
Tk.mainloop()
