This project demonstrates the use of multithreading in a PyQt6 application to manage character appending and deleting to a QLineEdit widget, with real-time updates on a simple ASCII progress bar.

App's Graphical User Interface

The application features a main window with:

• A read-only QLineEdit where characters are appended and deleted.
• An ASCII progress bar that visually represents the percentage of characters in the QLineEdit.
• A text box to set the delay for deleting characters.
• A start button to initiate the threads.

• Appending Characters: Three threads (thread1, thread2, thread3) continuously append characters ('p', 's', 't') to the text box.
• Deleting Characters: A separate thread (deleting_thread) continuously removes the last character from the text box based on a user-defined delay.
• Progress Bar: Updates in real-time to reflect the current percentage of the maximum 40 characters allowed in the text box.

Ensure you have Python installed along with PyQt6. You can install PyQt6 using pip if it's not already installed:

pip install PyQt6

Clone this repository and navigate to the directory containing multithread.py. Run the following command to start the application:

python multithread.py

• MainWindow: Manages the UI and threads.
• Worker: Handles the appending of characters.
• DeletingWorker: Manages the deletion of characters.

Each worker is moved to a separate QThread to ensure that the GUI remains responsive.
