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.

Approaching LiveBindings 

The FMX framework comes with a piece of technology known as LiveBindings. It's expression-based and designed around the observer pattern. Expressions can involve different kinds of members, including data sources (object-oriented or dataset-oriented) and user interface (UI) elements (controls).

The LiveBindings engine holds expression definitions and gathers and dispatches events. It does this by, for example, collecting a member's value change notification and reevaluating every expression where the member is involved. This same technology is also available in VCL, and design-time support has been added to the IDE on purpose (we already looked at the LiveBindings Designer earlier in this book in Chapter 2, Exploring the Similarities and Differences of VCL, and Chapter 4, Discovering Lists and Advanced Components).

LiveBindings is quite a broad technology that's simple in theory but has some layering and peculiarities you must consider...
