我在引用框架内创建的顶层时遇到问题。
我对 python 还是比较陌生，所以任何帮助都会很棒。
当 searchList(Entry) 尝试将数据导入到 contactMenu(Toplevel) 实例时，就会出现问题。
from Tkinter import *
emailList = ['one.two@gmail.com','two.three@gmail.com','five.six@gmail.com','seven.eight@gmail.com']

def set_completion_list(self, completion_list):
self._completion_list = completion_list
self._hits = []
self._hit_index = 0
self.position = 0
self.bind('<KeyRelease>', self.handle_keyrelease)
def autocomplete(self, delta=0):
"""autocomplete the Entry, delta may be 0/1/-1 to cycle through possible hits"""
if delta: # need to delete selection otherwise we would fix the current position
self.delete(self.position, END)
else: # set position to end so selection starts where textentry ended
self.position = len(self.get())
# collect hits
_hits = []
_hits.sort(key=str.lower)
for element in self._completion_list:
if element.startswith(self.get().lower()):
_hits.append(element)
# if we have a new hit list, keep this in mind
if _hits != self._hits:
self._hit_index = 0
self._hits=_hits
# only allow cycling if we are in a known hit list
if _hits == self._hits and self._hits:
self._hit_index = (self._hit_index + delta) % len(self._hits)
# now finally perform the auto completion
if self._hits:
contactsMenu.displayField.delete(0, END)
#contacts.displayField.insert(0,self._hits)
self.select_range(self.position,END)
for items in range(0, len(self._hits)):
contactsMenu.displayField.insert(0,self._hits[items])
