我以前用tkinter接口在2.7中创建了一个程序我现在试图将它合并到3.5.2程序中,但是我有很多错误,我不确定是否这是由于Python3.5.2的tkinter中的软件包更改所致。主要的问题是要做下面的下拉菜单将是我的2.7版本以及错误的3.5.2和解决方案我尝试了错误。Python 3.5 tkinter下拉菜单
Tkinter的代码的Python 2.7:
from Tkinter import *
import tkMessageBox
OPTIONS = [
"Homepage",
"Instructions",
"Contact Page"
]
root = Tk()
root.title("Tittle")
root.geometry('700x300')
var = StringVar(root)
var.set("Menu")
#var.set(OPTIONS[0])
menu = apply(OptionMenu, (root, var) + tuple(OPTIONS))
menu.pack(side=TOP, anchor=W)
#Set the separator between the menu and the buttons
separator = Frame(height=2, bd=1, relief=SUNKEN)
separator.pack(fill=X, padx=1, pady=20)
top = Frame(root)
center = Frame(root)
bottom = Frame(root)
top.pack(side=TOP)
center.pack(side=TOP)
bottom.pack(side=BOTTOM, fill=BOTH, expand=True)
#Method to change the GUI when an option from the Menu is selected
def change_age(*args):
if var.get()=="Homepage":
b1.pack(in_=center, side=LEFT)
b2.pack(in_=center, side=LEFT)
b3.pack(in_=center, side=LEFT)
b4.pack(in_=center, side=LEFT)
if var.get()=="Instructions":
L1.pack(in_=center, side=LEFT)
var.trace('w', change_age)
# create the widgets for the top part of the GUI
b1 = Button(root, text="Database Parser", height=5)
b1.place(x=170, y=500)
b2 = Button(root, text="Web Crawler", height=5)
b3 = Button(root, text="Password Generator", height=5)
b4 = Button(root, text="Dictionary Attack", height=5)
#Instructions labels
L1 = Label(root, text="Instructions:\nHere you can write all your instructions")
L2 = Label(root, text="Contact Page:\nHere you can write all your contact information")
b1.pack(in_=center, side=LEFT)
b2.pack(in_=center, side=LEFT)
b3.pack(in_=center, side=LEFT)
b4.pack(in_=center, side=LEFT)
root.mainloop()
3.5.2解决方法一:
from tkinter import *
from tkinter.filedialog import askopenfilenames
import sys
OPTIONS = [
'HOME'
'INSTRUCTIONS'
]
root = Tk()
root.title('Title')
root.geometry('700x300')
var = StringVar(root)
var.set("Menu")
menu = apply(OptionMenu, (root, var) + tuple(OPTIONS))
menu.pack(side=TOP, anchor=W)
separator = Frame(height=2, bd=1, relief=SUNKEN)
separator.pack()
top = Frame(root)
center = Frame(root)
bottom = Frame(root)
top.pack(side=TOP)
center.pack(side=TOP)
bottom.pack(side=BOTTOM, fill=BOTH, expand=True)
#Method changes GUI when an option from menu is selected
"""
def change_layout(*args):
if var.get()=='Homepage':
b1.pack(in_=center, side=LEFT)
b2.pack(in_=center, side=LEFT)
b3.pack(in_=center, side=LEFT)
if var.get()=='Instructions':
b1.pack_forget()
b2.pack_forget()
b3.pack_forget()
"""
def load_file():
fname = askopenfilenames(filetypes= (("Text Files", ".txt"),
("HTML Files", "*.html;*.htm"),
("All Files", "*.*")))
if fname:
try:
print('Files loaded')
except OSError as Error:
print('Files encountered error while loading')
# widgets for the top part of the GUI
b1 = Button(root, text='Select Files', height=5, command=load_file)
b1.place(x=170, y=500)
b2 = Button(root, text='Run Program', height=5)
b3 = Button(root, text='Save Results', height=5)
b1.pack(in_=center, SIDE=LEFT)
b2.pack(in_=center, SIDE=LEFT)
b3.pack(in_=center, SIDE=LEFT)
#Instructions - TODO Later date
root.mainloop()
解决方案的一个错误: 与
menu = apply(OptionMenu, (root, var) + tuple(OPTIONS))
说明NameError出现第一个问题:名字'apply'没有被定义。我的第一个想法是删除它,并继续认为它可能不需要在python 3.5.2,然后它告诉我我不能运行代码“menu.pack(SIDE = TOP,锚= W)”错误代码:
AttributeError: 'tuple' object has no attribute 'pack'
3.5.2解决方案2:
from tkinter import *
from tkinter.filedialog import askopenfilenames
import sys
class drop_down_menu(OptionMenu):
def __init__(self, master, menu, *options):
self.var = StringVar(master)
self.var.set('Menu')
OptionMenu.__init__(self, master, self.var, *options)
self.init_ui()
def init_ui(self):
self.master.title('Test')
self.pack(fill=BOTH, expand=1)
OPTIONS = [
'HOME'
'INSTRUCTIONS'
]
root = Tk()
root.title('Title')
root.geometry('700x300')
menu = drop_down_menu(root, 'Menu', OPTIONS)
menu.place
separator = Frame(height=2, bd=1, relief=SUNKEN)
separator.pack()
top = Frame(root)
center = Frame(root)
bottom = Frame(root)
top.pack(side=TOP)
center.pack(side=TOP)
bottom.pack(side=BOTTOM, fill=BOTH, expand=True)
#Method changes GUI when an option from menu is selected

def load_file():

使用方法二,我是能够获得通过菜单错误,但现在收到此错误信息,我只是失去了,为什么这所有的工作没有2.7上的问题,但现在拒绝在3.5.2上做任何事情:
Traceback (most recent call last):
File "C:/Users/Lewis Collins/PycharmProjects/Home.py", line 86, in <module>
b1.pack(in_=center, SIDE=LEFT)
File "C:\Users\Lewis Collins\AppData\Local\Programs\Python\Python35-32\lib\tkinter\__init__.py", line 1991, in pack_configure
+ self._options(cnf, kw))
_tkinter.TclError: bad option "-SIDE": must be -after, -anchor, -before, -expand, -fill, -in, -ipadx, -ipady, -padx, -pady, or -side
提前感谢您的任何帮助或反馈。
对于最后一个,它应该是小写'side ='。不是'SIDE ='。 – Lafexlos
关于[apply](http://python3porting.com/differences.html#apply)。我没有时间来形成完整的答案,所以我希望别人会这样做。我只是在投入一些资源。 – Lafexlos
@Lafexlos谢谢我现在正在运行,但快速问题我的菜单栏正在占用整个区域,并且下拉菜单不会用新行分隔,关于如何将菜单缩小为字符串长度的任何想法'菜单' –
