QR Code Generator App

Project Overview

The main aim of this project is to create a QR code for any website submitted via the app. The app provides a user-friendly interface for generating customizable QR codes with different patterns, colors, and sizes. It also validates the submitted URL and allows users to save the generated QR code with a timestamped filename.

Project Structure

The project consists of two main Python files:

1. app.py (Frontend using PyQt5)
2. qrcode_gen.py (QR Code generation and URL validation logic)

app.py

This file contains the frontend code for the app built with PyQt5. The app provides:

• An input field to enter the URL for which a QR code is to be generated.
• Two buttons:
  1. Generate QR Code: Generates a QR code with random patterns, colors, and backgrounds.
  2. Save QR Code: Saves the generated QR code with a default timestamped filename.
• A display area that shows the QR code once it is generated. Each time the "Generate QR Code" button is clicked, a new QR code with a different design is displayed.

Additional features:

• If the URL entered is invalid, an error message is displayed, asking the user to input a valid URL.
• Once the QR code is saved, a popup message confirms that the QR code has been successfully saved.

qrcode_gen.py

This file contains the core logic for QR code generation and URL validation:

• generate_qr_code function: This function is called by app.py to generate the QR code when the user clicks the "Generate QR Code" button.
• URL validation is also handled in this file, ensuring the URL format is correct before generating the QR code.
• QR codes are generated with random patterns, colors, and fixed sizes, offering a variety of styles.
• QR codes are saved with a default timestamp as filename in a specified folder.

Results

Sample output showing various QR codes generated by the app with different patterns and background colors.
