Event-driven programming in GUI development is a paradigm where the program's flow is determined by user interactions, such as:

- Mouse clicks

- Key presses

- Window resizing

- Button clicks

In event-driven programming:

1. The program waits for an event to occur.

2. When an event occurs, the program responds by executing a specific block of code (event handler).

3. The event handler processes the event and updates the GUI accordingly.

4. The program returns to waiting for the next event.

Event-driven programming allows for:

- Responsive and interactive GUIs

- Efficient use of system resources

- Modular and reusable code

- Easy integration of new features and functionality

Common events in GUI development include:

- Button clicks

- Text input

- Mouse movements

- Window events (open, close, resize)

- Keyboard events (key presses, key releases)

By using event-driven programming, developers can create dynamic and user-friendly GUI applications that respond to user interactions in a timely and efficient manner.
