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.

Introducing managed bindings

As we've already mentioned, a binding is basically made up of an expression that ties a Source and a Target control together. Typically, it evaluates the expression against certain properties of the Source control in order to assign the result to certain properties of the Target control. Let's start with a simple example. Here, we will try to tie the Text property of a TEdit instance to the Text property of a TButton instance.

Follow these steps in your IDE:

  1. Create a new, blank FMX application.
  2. Drop a TEdit and TButton component onto your form (we'll keep their default names of Edit1 and Button1).
  3. Drop a TBindingList component onto your form.
  4. Add a new binding expression to your binding list (double-click on the TBindingList component and click on the New binding button, the first on the left in the component editor toolbar).
  5. Find the TBindExpression entry in the list shown in the New LiveBinding dialog that appears...
