Qt Event Loop, Networking and I/O API

Explore the intricacies of Qt's event loop, networking, and I/O API in this comprehensive CppNow conference talk. Dive into the evolution of Qt from a simple cross-platform GUI toolkit to a powerful framework supporting various subsystems. Learn about Qt's central event-handling loop and its role in asynchronous mechanisms. Discover how to implement asynchronous I/O support for child processes, TCP connections, and UDP I/O. Gain insights into Qt's high-level support for HTTP and FTP operations. Through examples and in-depth explanations, understand the implementation details and practical applications of these subsystems. Suitable for both application developers and library creators, this talk covers Qt API basics, naming conventions, events, signals, inspection, string matching, emit, connection types, abstract dispatcher, qtimer, socket notifications, signal emission, and nested event loops. Enhance your understanding of Qt's powerful asynchronous capabilities and learn how to leverage them in your projects.
