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.

Learning about the TAnimation class

The TAnimation class, which is contained in the FMX.Ani.pas source file, is a TFMXObject descendant and is the ancestor of TCustomPropertyAnimation (it is the ancestor of most animation components in FMX). This class also holds an instance of the global timer FMX uses to notify the running animations that time has passed.

In this section, we will learn about the TAnimation class, along with its inherited classes, in detail. We'll also learn about the global animation functions and interpolation modifier functions associated with it. 

The TCustomPropertyAnimation descendant class uses Run Time Type Information (RTTI) functionalities to attach the animation to a specific property of the Parent component. This way, you can add a TCustomPropertyAnimation (descendant) to any FMX object and address one of the properties with the animation's execution. The ability to refer to the property by name (string) means you can configure...
