Overview of this book

FireMonkey (FMX) is a cross-platform application framework that allows developers to create exciting user interfaces and deliver applications on multiple operating systems (OS). This book will help you learn visual programming with Delphi and FMX. Starting with an overview of the FMX framework, including a general discussion of the underlying philosophy and approach, you’ll then move on to the fundamentals and architectural details of FMX. You’ll also cover a significant comparison between Delphi and the Visual Component Library (VCL). Next, you’ll focus on the main FMX components, data access/data binding, and style concepts, in addition to understanding how to deliver visually responsive UIs. To address modern application development, the book takes you through topics such as animations and effects, and provides you with a general introduction to parallel programming, specifically targeting UI-related aspects, including application responsiveness. Later, you’ll explore the most important cross-platform services in the FMX framework, which are essential for delivering your application on multiple platforms while retaining the single codebase approach. Finally, you’ll learn about FMX’s built-in 3D functionalities. By the end of this book, you’ll be familiar with the FMX framework and be able to build effective cross-platform apps.

Using native HTTP client implementations

Network interaction is becoming more and more common in most applications. Delphi developers have had the opportunity to deal with networking using Indy (https://www.indyproject.org/). It is an open source client/server communication library supporting low-level (TCP, UDP, and more) and high-level (FTP, HTTP, and more) protocols.

In this section, we'll understand the use of HTTP client implementations. These are native to each platform and conveniently wrapped by the Delphi RTL to provide developers with a common, handy way to develop single code base applications featuring HTTP client capabilities.

With the stress of multi-platform applications and distributed applications, the HTTP protocol has become more and more important among others (the world is now dominated by REST services). The need for security has also pushed most services to shift toward HTTPS (now an industry standard even for basic things).

Indy relies on OpenSSL implementation...
