问题描述
我想从一个大列表中生成多个复选框,并获取所有值。
I would like to generate multiple checkboxes from a large list, and get all the values.
到目前为止,这是我的代码(列表可能更大) :
Here is my code so far (the list could be much larger):
from Tkinter import *
def print_ingredients(*args):
values = [('cheese',cheese.get()),('ham',ham.get()),('pickle',pickle.get()),('mustard',mustard.get()),('lettuce',lettuce.get())]
print values
lst = ['cheese','ham','pickle','mustard','lettuce']
top = Tk()
mb= Menubutton ( top, text="Ingredients", relief=RAISED )
mb.grid()
mb.menu = Menu ( mb, tearoff = 0 )
mb["menu"] = mb.menu
cheese=IntVar()
ham=IntVar()
pickle=IntVar()
mustard=IntVar()
lettuce=IntVar()
l = mb.menu.add_checkbutton(label="cheese", variable = cheese)
l = mb.menu.add_checkbutton(label="ham", variable = ham)
l = mb.menu.add_checkbutton(label="pickle", variable = pickle)
l = mb.menu.add_checkbutton(label="mustard", variable = mustard)
l = mb.menu.add_checkbutton(label="lettuce", variable = lettuce)
btn = Button(top, text="Print", command=print_ingredients)
btn.pack()
mb.pack()
top.mainloop()
这可以按预期工作,但是当列表很大时,似乎不必将所有内容都写出来。
This works as intended but when it is a much larger list it seems unnecessary to write all of this out.
是否有办法仅通过遍历字符串列表来创建复选框/复选框(然后获取其值)?
Is there a way to create the checkboxes/checkbuttons (and then get their values) solely by iterating through the list of strings?
推荐答案
是的。您将需要将数据存储在某个地方。我建议做一本字典。
Yes. You will need to store the data somewhere. I suggest making a dictionary.
from Tkinter import *
INGREDIENTS = ['cheese','ham','pickle','mustard','lettuce']
def print_ingredients(*args):
values = [(ingredient, var.get()) for ingredient, var in data.items()]
print values
data = {} # dictionary to store all the IntVars
top = Tk()
mb= Menubutton ( top, text="Ingredients", relief=RAISED )
mb.menu = Menu ( mb, tearoff = 0 )
mb["menu"] = mb.menu
for ingredient in INGREDIENTS:
var = IntVar()
mb.menu.add_checkbutton(label=ingredient, variable=var)
data[ingredient] = var # add IntVar to the dictionary
btn = Button(top, text="Print", command=print_ingredients)
btn.pack()
mb.pack()
top.mainloop()
