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.

Understanding LiveBindings methods

We've already seen that the TBindingLists component provides access to a set of methods you can use in your expressions (we also learned how to register our own methods in the system via the SquareInvocable example).

Methods are system-wide, so we need to refer to the System.Bindings.Methods unit (if your Delphi edition includes RTL sources, this can be a good place to look when you're in need of inspiration to define your own methods). A method can have arguments and return a value. Let's have a look at some built-in methods:

  • IfThen(Condition, Value1, Value2) implements the inline if (ternary) operator. It requires all three arguments to be specified, and all of them can be values or expressions. If the Condition argument evaluates to True, the function returns Value1; otherwise (when Condition is False), Value2 is returned. Obviously, if Value1 and/or Value2 are expressions, the result will be the evaluation result of...
