循环实例化窗口小部件到不同的框架python / tkinter

Question

我正在用python创建一个简单的GUI生产计算器。 我正在使用Tkinter，并且有一个带有10个标签的主机。 我已经创建了所有条目，函数完成了我们需要的计算，并且一切正常。 我的问题是我想在每个选项卡line10-line19上使用这些条目和标签。 我可以手动为每个选项卡重新创建代码，但这似乎不是很pythonic。 我希望能够将这段代码放入一个循环中，该循环将重命名每行的变量名称，并通过更改grid方法中的参数将对象放置在不同的选项卡框架中。 我希望我很清楚自己是个新人，并希望对这种语言有所了解。 我希望能够在所有变量名的末尾用不同的数字重复此代码，串联是否有效？

这是我的代码。

Answer 1

pythonic解决方案是使每个笔记本选项卡成为自定义类的实例。 它看起来像这样：

class NotebookTab(Frame):
    def __init__(self, parent):
        Frame.__init__(self, parent)

        self.create_widgets()

        def create_widgets(self):
            self.ctlabelj = Label(self, text = "Cycle Time:")
            self.ctlabelj.grid(row=2, column=0)
            self.cycletime = StringVar()
            self.cycletime.trace('w', proj)
            self.cycletimeentj = Entry(self, textvariable=self.cycletime)
            self.cycletimeentj.grid(row=2,column=1)

            moldoptionsj = [1, 1, 2, 3, 4]
            self.vj = IntVar()
            ...

for linenumber in range(10, 20):
    tab = NotebookTab(notebook, text="Line %d" % linenumber)
    notebook.add(self)

好吧，使用循环很容易：看一下（我认为只有一个问题）…

from Tkinter import *
from ttk import *
import time

class supervisorcalc:
    def __init__(self, master):
        self.notebook = Notebook(master)
        self.lines = {}

        for i in range(10, 20):
            self.lines[i] = Frame(self.notebook)
            self.notebook.add(self.lines[i], text="Line" +  str(i))

        self.notebook.grid(row=0,column=0)
