Delphi GUI Programming with FireMonkey

By: Andrea Magni

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 the Style Designer

A style object definition contains enough information to describe the organization of a set of components. It also includes the values of the components' properties. In practical terms, you may think of style as a (portion of a) Delphi UI definition without code and event handlers implementation. From a certain point of view, you may see the Form Designer (the IDE central window) as an editor for the style of your application.

There is another tool introduced specifically to manipulate FMX styles (and/or portions of them) within the Delphi IDE, which is the Style Designer.

In the previous section, I have shown you what FMX files look like and told you that styles are stored in the same format. If you drop a TStyleBook component on your form and activate the editing mode (double-click on it), the Style Designer will pop up.

The key parts of the IDE that are involved are as follows:

  • The Structure View (which will list the contents of ...
