Python GUI Program with Submit and Reset Buttons

Aim:Write a GUI program to create a window wizard having two text labels, two text fields and two buttons as Submit and Reset

Program:


import tkinter as tk

def write_text():
    print("Tkinter is easy to create GUI!")

parent = tk.Tk()
frame = tk.Frame(parent)
frame.pack()

text_disp= tk.Button(frame,
                   text="SUBMIT",
                   command=write_text
                   )

text_disp.pack(side=tk.LEFT)

exit_button = tk.Button(frame,
                   text="RESET",
                   fg="green",
                   command=quit)
exit_button.pack(side=tk.RIGHT)

parent.mainloop()

Sample Viva Questions and Answers

What is a GUI program?
A GUI (Graphical User Interface) program allows users to interact with software through graphical elements like windows, buttons, and text fields instead of text-based commands.
What is the purpose of the window wizard in this program?
The window wizard serves as a user-friendly interface for inputting data through text fields and provides options to submit or reset the entered information.
What are the main components of the GUI in this program?
The main components include two text labels, two text fields for user input, and two buttons labeled “Submit” and “Reset.”
What is the function of the Submit button?
The Submit button is used to process the data entered in the text fields, typically by validating the input and performing an action such as saving or displaying the data.
What does the Reset button do?
The Reset button clears the text fields, allowing the user to start over without any previously entered data.
How can you create text labels in a GUI?
Text labels can be created using GUI library functions that allow you to define and display static text on the window.
What is the significance of text fields in the GUI?
Text fields allow users to input data, making the interface interactive and enabling data collection.
Which libraries can be used to create GUI applications in Python?
Common libraries for creating GUI applications in Python include Tkinter, PyQt, and Kivy.
How can you handle events in a GUI program?
Events can be handled by defining callback functions that are triggered when users interact with GUI elements, such as clicking buttons.
What are some practical applications of GUI programs?
GUI programs are used in various applications, including data entry forms, configuration wizards, and user management systems, enhancing user experience and accessibility.
