I want to make a benchmark app in python using Tkinter-CodePudding

I want it to show the user input but it is not showing. Please send help. I have tried code from multiple posts but no luck. I was able to make it show the 'selected' option but for no avail. Please help me

import tkinter as tk
from tkinter.ttk import *
app = tk.Tk()
# Functions and scripts
def OnSubmit():
    print(str(usrnme.get()))
    print(str(passw.get()))
    print(str(selected.get()))

app.title("Pymark: Landing Page")
app.geometry("600x600")
app.resizable(0, 0)
desc = """

PyMark is the first benchmark created using python's native GUI creator "Tkinter" and using hashes to rank performance.
The sofware is light and can run on older CPU's like i7-4510U (the processor I use) and does not require a lot of memory.
I am still open for constructive critisism and community feedback on my work as I am a beginner programmer.

IMPORTANT: PyMark can still experience bugs thus, pull requests are encouraged!

Please continue enjoying PyMark!

# Landing Page
lpframe = Frame(app)
mainheading = Label(lpframe, text="Welcome to PyMark!", font = ('Times New Roman', 20))
maindesc = Label(lpframe, text=f'{desc}', font = ('Times New Roman', 9))
lpframe.pack()
mainheading.pack(padx = 10, pady = 10)
maindesc.pack(padx = 10, pady = 10)
# Login Page
loginframe = Frame(app)
headerframe = Frame(loginframe, relief = 'groove')
loginheader = Label(headerframe, text='Login / Register: ', font = ('Times New Roman', 12))
usrnmelb = Label(loginframe, text = 'Username: ', font = ('Times New Roman', 9))
passlb = Label(loginframe, text = 'Password: ', font = ('Times New Roman', 9))
selected = tk.StringVar()
register = Radiobutton(loginframe, text='Register', value='reg', variable=selected)
login = Radiobutton(loginframe, text='Login', value='log', variable=selected)
submitbtn = Button(loginframe, text = 'Submit', command=OnSubmit)
usrnmeentr = Entry(loginframe)
passentr = Entry(loginframe)
loginframe.pack()
headerframe.pack(padx = 20, pady = 20)
loginheader.pack(padx = 20, pady = 20)
usrnmelb.pack()
usrnmeentr.pack()
passlb.pack()
passentr.pack()
register.pack()
login.pack()
submitbtn.pack(padx = 10, pady = 10)
usrnme = tk.StringVar()
passw = tk.StringVar()
usrnmeentr.focus()
app.mainloop()

I expected it to return the username, password and the selected option but it only told the selected option and nothing else.

CodePudding user response：

The OnSubmit() function does not get the correct inputs to print. Get the entryfields content with the method .get(). In your case the OnSubmit() function should look like this:

def OnSubmit():
    print(str(usrnmeentr.get())) #usrnme.get() was not the name of the entry box
    print(str(passentr.get()))
    print(str(selected.get()))

CodePudding user response：

You must link your Entry to Stringvar(), not your radio buttons

import tkinter as tk

app = tk.Tk()
app.geometry('300x300')


# Functions and scripts
def OnSubmit():
    print(var.get())


var = tk.StringVar()
entry = tk.Entry(app, textvariable=var)
entry.pack()

bt = tk.Button(app, text='Show', command=OnSubmit)
bt.pack()
app.mainloop()
