## What it is
A collection of 100+ independent open-source Qt/QWidget demo projects written in C++, each a standalone project with clean, well-commented code. It supports Qt4/5/6 and runs on Windows, Linux, and macOS, aimed primarily at Qt beginners.

## Use cases
- learn Qt widget programming with example code
- find a serial port debugging assistant demo
- see how to build custom Qt controls like battery or nav buttons
- copy sample code for log redirection in a Qt app
- study small complete Qt projects as a beginner
- get a network debugging tool example in C++

## When to choose
- you are learning Qt and want many small, readable, commented examples
- you need reference implementations of common custom widgets or small tools
- you want code that compiles across Qt4/5/6 and multiple operating systems

## When to avoid
- you need a production-ready library with a stable API and clear license terms
- you want a single unified framework rather than many independent demo projects
- your project is not C++/Qt based

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, gui, ui-components, logging, serialization
- domain: developer-tools, tutorials, cross-platform, desktop-applications
- platform: windows, cpp, cross-platform
- tags: qt, qwidget, demo-collection, beginner-friendly, c-plus-plus, sample-code, linux, macos
