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.

Mastering real-world data bindings

So far, we have looked at a few examples of managed bindings, where the developer needs to explicitly trigger the evaluation of the binding in order to update the target. This kind of approach lets the developer have full responsibility and control over what happens in the application. This means that a normal-sized application may become hard to write/maintain because everything is left to the developer (reducing the advantage of a declarative versus imperative approach, whose simplicity is somehow the background concept for the entire thing), but also that the developer always has the opportunity to fine-tune the binding mechanism, thus keeping everything under control.

Apart from TBindExpression (and TBindExprItems), there are other kinds of LiveBindings available for different purposes. We'll provide an overview of the most significant use cases in the remainder of this chapter.

However, before we look at these LiveBindings, we need...
