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 visual layouts

In this section, we will learn about the various visual layouts/components.

UI is made of visual components (eventually with the aid of some other non-visible ones). By layout, we are usually referring to the strategy used to place these visual components in front of the user.

The placement of components always follows a particular model, for example, the box model where components can be regarded as rectangular-shaped boxes, hence, with a width and a height, and positioned using a set of coordinates (relative to a conventional origin). In our case, the origin is set to be the upper-left corner of the parent container of the component and, by convention again, the placement is expressed in coordinates of the upper-left corner of the component.

Delphi historically has adopted this model for placement of visual components in conjunction with the concept of parenthood. In the VCL framework, every component needs to have a Parent object: a visual component will be...
