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.

TSpeedButton

Another very common component is TSpeedButton. Its main difference compared to a standard TButton is that it does not capture focus (this means you can click on it without moving the focus from another component). This can be very useful when you're implementing toolbars since you may want to perform some actions on a previously selected piece of text (that is, in a memo component) or on a row of a grid/list control.

TSpeedButton usually looks different (somewhat less important) from a standard button, but you can easily change its appearance by setting its StyleLookup property to the buttonstyle value. Other styles come in handy when you want to implement the typical segmented control (sometimes named scope bar) that you can find in several applications. You can think of it as a set of buttons, one adjacent to the other, with some visual peculiarities for the first and last buttons of the set. From a behavior point of view, you can configure it to have independent...
