python中的simpledialog.SimpleDialog，带有2个输入H

Question

我想知道是否有可能在 python 中获得一个带有 2 个输入的 simpledialog.SimpleDialog。文档对此并不清楚，我在网上找不到任何有关此的信息。

我想得到的最终结果是这样的： 一个输入框，每个变量有 2 行

|---------------------|
|Input 1 | ' text abc'|
|---------------------|
|Input 2 | ' Text fgh'|
|---------------------|

提前致以诚挚的问候和感谢

我假设你在追求这样的事情：

official documentation 解释了如何做所有事情，这远远超出了您现在的需要。

您需要标签小部件、入口小部件、按钮小部件和打包器几何管理器。

ZetCode 对你来说可能是一个很好的教程，这个答案部分基于他的代码：

#### Save this as dual_input.py ####
#! /usr/bin/env python
# -*- coding: utf-8 -*-

from tkinter import Tk, Text, TOP, BOTH, X, N, LEFT, RIGHT
from tkinter.ttk import Frame, Label, Entry, Button

# Good habit to put your GUI in a class to make it self-contained
class SimpleDialog(Frame):

    def __init__(self):
        super().__init__()
        # self allow the variable to be used anywhere in the class
        self.output1 = ""
        self.output2 = ""
        self.initUI()

    def initUI(self):

        self.master.title("Simple Dialog")
        self.pack(fill=BOTH, expand=True)

        frame1 = Frame(self)
        frame1.pack(fill=X)

        lbl1 = Label(frame1, text="Input 1", width=6)
        lbl1.pack(side=LEFT, padx=5, pady=10)

        self.entry1 = Entry(frame1, textvariable=self.output1)
        self.entry1.pack(fill=X, padx=5, expand=True)

        frame2 = Frame(self)
        frame2.pack(fill=X)

        lbl2 = Label(frame2, text="Input 2", width=6)
        lbl2.pack(side=LEFT, padx=5, pady=10)

        self.entry2 = Entry(frame2)
        self.entry2.pack(fill=X, padx=5, expand=True)

        frame3 = Frame(self)
        frame3.pack(fill=X)

        # Command tells the form what to do when the button is clicked
        btn = Button(frame3, text="Submit", command=self.onSubmit)
        btn.pack(padx=5, pady=10)

    def onSubmit(self):

        self.output1 = self.entry1.get()
        self.output2 = self.entry2.get()
        self.quit()

def main():

    # This part triggers the dialog
    root = Tk()
    root.geometry("250x150+300+300")
    app = SimpleDialog()
    root.mainloop()
    # Here we can act on the form components or
    # better yet, copy the output to a new variable
    user_input = (app.output1, app.output2)
    print(app.output1)
    # Get rid of the error message if the user clicks the
    # close icon instead of the submit button
    # Any component of the dialog will no longer be available
    # past this point
    try:
        root.destroy()
    except:
        pass
    # To use data outside of function
    # Can either be used in __main__
    # or by external script depending on
    # what calls main()
    return user_input

# Allow dialog to run either as a script or called from another program
if __name__ == '__main__':
    follow_on_variable = main()
    # This shows the outputs captured when called directly as `python dual_input.py`
    print(follow_on_variable)
