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.

Building a 3D "Hello, world!" application

In the Delphi IDE, select Create new Multi-Device Application and choose 3D Application from the dialog window that will pop up. You will see the dialog in the following screenshot, with the 3D Application entry highlighted:

The IDE will prepare the new application by adding a form. Differently from what we are used to, this form inherits from the FMX.Forms3D.TForm3D class rather than the FMX.Forms.TForm class. It basically incorporates an instance of FMX.Types3D.TContext3D and implements the FMX.Controls3D.IViewport3D interface. This enables the form to act as a host for 3D controls.

In other words, the form will be used as a 3D container for our scene. However, many other aspects of the form are unchanged with respect to the TForm (2D) version. For example, you can change the Color property of the form from the default value (White) to a custom value (Silver) and you'll notice the change immediately...
