Get Strings from Entry Boxes

[360monkey]

Hey Bytes Community!

I am learning Tkinter GUI and have come across a problem.

from Tkinter import *
import random
 
class App:
 
    def __init__(self, master):
        frame = Frame(master)
        frame.pack()
        menu = Menu(root)
        root.config(menu=menu)
        filemenu = Menu(menu)
        menu.add_cascade(label='File', menu=filemenu)
        filemenu.add_command(label='Practice', command=self.namesetare)
        filemenu.add_command(label='Story Mode', command=self.namesetadv)
        filemenu.add_command(label='Quit', command=frame.quit)
        infomenu = Menu(menu)
        menu.add_cascade(label='About...', menu=infomenu)
        infomenu.add_command(label='About BattlerIII', command=self.about)
 
    def namesetare(self):
        nsa = Toplevel()
        self.pone = Label(nsa, text='Player One:').grid(row=0)
        self.e1 = Entry(nsa).grid(row=0, column=1)
        self.ptwo = Label(nsa, text='Player Two:').grid(row=1)
        self.e2 = Entry(nsa).grid(row=1, column=1)
        self.next = Button(nsa, text='Next', command=self.arena)
        self.next.grid(row=2, column=1)
        return self.e1
 
    def arena(self):
        areone = Toplevel()
        hmn1 = str(self.e1.get())
        hmn2 = str(self.e2.get())
        self.text1 = Label(areone, text=hmn1)
        self.text1.pack()
        aretwo = Toplevel()
        self.text2 = Label(aretwo, text=hmn2)
        self.text2.pack()
        self.attack1 = Button(areone, text='ATTACK', fg='red', command=self.atk1)
        self.attack1.pack(side=LEFT)
        self.attack2 = Button(aretwo, text='ATTACK', fg='red', command=self.atk2)
        self.attack2.pack(side=LEFT)
 
root = Tk()
root.title('BattlerIII')
app = App(None)
root.mainloop()

what i want to do (the important parts are underlined), is be able to recall the strings inputted in the GUI.
so if i said:

print(hmn1)
it would say what was put into the entry boxes.

similarly, a = input('')
print(a)

any help would be appreciated!
Thanks!

Save the entry widgets to self.e1 and self.e2. Apply grid() to the widget objects separately. In Entry(), set textvariable to a StringVar object. I modified method namesetare() below.

    def namesetare(self):
        nsa = Toplevel()
        self.pone = Label(nsa, text='Player One:').grid(row=0)
        self.v1 = StringVar()
        self.e1 = Entry(nsa, textvariable=self.v1)
        self.e1.grid(row=0, column=1)
 
        self.ptwo = Label(nsa, text='Player Two:').grid(row=1)
        self.v2 = StringVar()
        self.e2 = Entry(nsa, textvariable=self.v2)
        self.e2.grid(row=1, column=1)
 
        self.next = Button(nsa, text='Next', command=self.arena)
        self.next.grid(row=2, column=1)
        self.next1 = Button(nsa, text='Quit', command=nsa.destroy)
        self.next1.grid(row=2, column=2)
        return self.e1

Set the value of the labels in the arena method to the same values used in the Entry widgets. Example:

        self.text1 = Label(areone, textvariable=self.v1)

The text in the label widgets is now linked to the text in the Entry widgets because they share the same values.
