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.

Exploring threads and tasks

Threads are a first-class citizen concept of modern operating systems and their model has been used for decades to implement the concurrent execution of different sets of instructions. In a very simplistic way, you can think of threads as independently executed lists of instructionsthere is a sequence in each list but they are independent of each other.

In this section, we will learn about the TThread class. We will also understand the thread's lifespan. We are going to familiarize ourselves a bit with the Parallel Programming Library, along with synchronization.

Other conceptualizations may render threads as independent agents executing their own program within the main program. In the end, they represent a way to organize code execution in order to do the following:

  • Take advantage of full hardware resources (modern CPUs have multiple processors/cores)
  • Deal with UI responsiveness
  • Deal with asynchronous operations (those operations have...
