How Would I Create A Reset Button For My Program Relating With The Following Code?

I am trying to add a reset button but I can't seem to get it to work. I created a main in order to refer back to it when the button is pressed but no luck. Any ideas? import sys fr

Solution 1:

By calling main() again, you are simply creating another instance of the GUI. What you should do instead is (if I understand correctly), reset the values of the currently existing GUI. You can use the set() method of the GUI objects.

Does

def reset_values():
    kiloMent.set(0)
    mileMent.set(0)
reset = Button(text="Reset Values!", command=reset_values).place(x=10, y=165)

do the trick?

Looking at your code more thoroughly, however, there are some other problems there, as well. To start with, I would suggest not creating a Label everytime the user tries to convert a value.

Solution 2:

This code should work:

from tkinter import *

def main():
    def closeWin():
        myGui.destroy()  # Close Window Function

    def kiloFunc():
        finalKilo.set(kiloMent.get() * 0.62)  # Kilometers to Miles Fuction

    def mileFunc():
        finalMile.set(mileMent.get() // 0.62)  # Miles to Kilometers Function

    def clearFunc():
        kiloMent.set("0")
        mileMent.set("0")
        finalKilo.set("")
        finalMile.set("")

    myGui = Tk()

    kiloMent = IntVar()
    mileMent = IntVar()

    finalKilo = StringVar()
    finalMile = StringVar()

    myGui.title("Distance Converter")
    myGui.geometry("450x200+500+200")

    myLabel = Label(text="Welcome! Please enter your value then choose your option:", fg="blue", justify='center')
    myLabel.pack()

    kiloEntry = Entry(myGui, textvariable=kiloMent, justify='center')
    kiloEntry.pack()

    kilo2milesButton = Button(text="Kilometers to Miles!", command=kiloFunc)
    kilo2milesButton.pack()

    mileEntry = Entry(myGui, textvariable=mileMent, justify='center')
    mileEntry.place(x=130, y=105)

    miles2kiloButton = Button(text="Miles to Kilometers!", command=mileFunc)
    miles2kiloButton.place(x=150, y=135)

    kiloLabel = Label(textvariable=finalKilo, fg='red', justify='center')
    kiloLabel.place(x=200, y=80)

    mileLabel = Label(textvariable=finalMile, fg='red', justify='center')
    mileLabel.place(x=200, y=170)

    reset = Button(text="Reset Values!", command=clearFunc)
    reset.place(x=10, y=165)

    quit = Button(text="Quit", command=closeWin)
    quit.place(x=385, y=165)

    myGui.mainloop()

main()

A few notes about your original code besides the ones that Chuck mentioned:

1. The math and sys imports were unused.
2. You were setting variables equal to widget.pack() and widget.place(), which are functions that return None.
