Question

我想将AutocompleteEntry中选择的变量传递给另一个形式或类中的另一个函数（即func2）。我尝试了如下

import Tkinter, tkFileDialog, Tkconstants , os
from Tkinter import *
import tkMessageBox as messagebox, Tkinter
import sys
import ttk
import tkFont
list1233 = ['a', 'actions', 'additional', 'also', 'an', 'and', 'angle', 'are', 'as', 'be', 'bind', 'bracket', 'brackets', 'button', 'can', 'cases', 'configure', 'course', 'detail', 'enter', 'event', 'events', 'example', 'field', 'fields', 'for', 'give', 'important', 'in', 'information', 'is', 'it', 'just', 'key', 'keyboard', 'kind', 'leave', 'left', 'like', 'manager', 'many', 'match', 'modifier', 'most', 'of', 'or', 'others', 'out', 'part', 'simplify', 'space', 'specifier', 'specifies', 'string;', 'that', 'the', 'there', 'to', 'type', 'unless', 'use', 'used', 'user', 'various', 'ways', 'we', 'window', 'wish', 'you']

# My frame for form

        self.parent = parent
        self.initialize()
        self.grid()        
    def initialize(self):
        # Dropdown Menu
        self.dropMenu2 = AutocompleteEntry(list1233)
        self.dropMenu2.grid(row=6, column=3)
    def func2(self,value2):
        print value2
        messagebox.showinfo("FileSave Status ", valu2)
class AutocompleteEntry(Entry):

        Entry.__init__(self, *args, **kwargs)

                    self.lb = Listbox()
                    self.lb.bind("<Double-Button-1>", self.selection)
                    print "satyaaa"

        value = widget.get(selection[0])

        if self.lb_up:
            print "I",self.lb.get(ACTIVE)

    def selection(self, event):

                self.lb.selection_clear(first=index)
                index = str(int(index)-1)                
                self.lb.selection_set(first=index)

def create_form(argv):
    form = simpleform_ap(None)
    w, h = form.winfo_screenwidth(), form.winfo_screenheight()
    form.geometry("1000x650")
    form.resizable(width=False, height=False)
    form.title('Meta Data Exporter')
    form.mainloop()
if __name__ == "__main__":
     global label123
     create_form(sys.argv)

它给出了错误TypeError： init （）正好接受2个参数（给定3个）。请帮帮我

您可以向 init 函数添加另一个变量，并在没有传递值时将其设置为None

# My frame for form
class simpleform_ap(Tk):
    def __init__(self,parent, entered_value=None):
        Tk.__init__(self,parent)
        ..
        ..

您是否也希望将方法或类作为行

中的父项传递

self.app = simpleform_ap(self.selection, enterednumber)   # Send it to Demo3 as an argument

你可能只想传递self而不是self.selection

如何在Python Tkinter中将变量值或Listbox值传递给另一个类的函数
