tkinter创建标签并动态托管

Question

我想创建一个简单的GUI,我可以输入一些值.前面和下面的标签以及启动脚本的按钮.

我使用的是这样的东西:

w = Label(master, text="weight:")
w.grid(sticky=E)
w = Label(root, text="bodyfathydrationmuscle:bones")
w.grid(sticky=E)
w = Label(root, text="hydration:")
w.grid(sticky=E)

没关系,但我想做动态.当我将w用于所有的命令时,我只能施放一次.但我需要我所有的数据;-)

我在考虑:

  def create_widgets(self):
    L=["weight","bodyfat","hydration","muscle","bones"]
    LV=[]
    for index in range(len(L)):
        print(index)
        print(L[index])
        ("Entry"+L[index])= Entry(root)
        ("Entry"+L[index]).grid(sticky=E)
        ("Label"+L[index])=Label(root, text=L[index])
        ("Label"+L[index]).grid(row=index, column=1)

稍后打电话:

var_weight=Entryweight.get()
var_bodyfat=Entrybodyfat.get()

等等.我怎么能让它发挥作用？

您的程序建议Entrybodyfat应该动态生成其他变量,但您不希望这样做.

通常的方法是将条目和标签存储在列表或地图中:

from Tkinter import *

root = Tk()

names = ["weight", "bodyfat", "hydration", "muscle", "bones"]
entry = {}
label = {}

i = 0
for name in names:
    e = Entry(root)
    e.grid(sticky=E)
    entry[name] = e

    lb = Label(root, text=name)
    lb.grid(row=i, column=1)
    label[name] = lb
    i += 1

def print_all_entries():
    for name in names:
        print entry[name].get()

b = Button(root, text="Print all", command=print_all_entries)
b.grid(sticky=S)

mainloop()

然后是bodyfat条目的值entry["bodyfat"].get().
