In a classical procedural program, how is the execution flow typically controlled?

By the order in which widgets are created in the GUI

By the operating system scheduling threads at runtime

By user interactions such as mouse clicks and key presses

By using constructs like loops, conditionals, and function calls

What is the 'event source' in a GUI application?

The widget or component that generates the event

The function that processes the event

The main window of the application

In an event-driven GUI application, what is the role of the event loop?

To compile the source code into executable machine code

To render the GUI widgets onto the screen only once at startup

To continuously wait for and dispatch events to the appropriate handlers

To store all user data in a database

A developer needs to build a GUI application that must run on Windows, macOS, and Linux with a native look and feel on each platform. The developer wants to minimize the amount of platform-specific code. Which choice is most appropriate?

Use platform-specific APIs directly on each operating system.

Use a command-line interface with graphical escape codes.

Use a cross-platform GUI toolkit such as Tkinter or PyQt.

Use a web-based interface served by a local HTTP server.

What is the core principle of visual programming as it relates to GUI development?

Designing the interface by arranging visual components rather than writing code for each element

Using only text-based commands to define the layout of the interface

Compiling the source code into machine code before execution

Writing all application logic in a single procedural script
