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.

Loading a style from embedded resources

Loading the style definitions from an external file is quite straightforward, thanks to the TStyleManager.SetStyleFromFile method and the TStyleBook.LoadFromFile/LoadFromStream methods.

Sometimes you don't want to rely on external files (for a number of reasons, ranging from higher intrinsic security for external modifications to easier deploying operations) and you have a chance to embed one or more styles into your application binary resources. We'll do this by taking the following steps:

  1. With your project open in the IDE, open the Project | Resources and Images ... menu entry. The following screenshot shows you the Resource and Images IDE dialog window:

  1. Add an FMX style file to the list of the resources, keeping RCDATA as the resource type but giving a unique name to the embedded resource (that is, MYSTYLE). This way, we instruct the IDE to include the file as a binary resource of the final executable.
Beware that...
