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.

Letting components flow as text with TFlowLayout

As we said, talking about responsiveness often means you need to rearrange components differently than originally designed and according to the actual characteristics of the device. While always keeping in mind that you can actually combine and nest FMX visual components as you wish, we are now going to introduce the TFlowLayout component.

As the name suggests, this will allow the developer to arrange a set of components, letting them flow in a very similar manner to how text runs in a Word processor. Elements will be running in a row, one beside the other, until the boundary of TFlowLayout is reached. Then the next element (the one not fitting the remaining space between the prior element and the layout boundary) is allowed to run over a new row.

The following screenshot shows you a TFlowLayout component with 15 children components (buttons):

As you can see, there is a vertical and horizontal gap of 10...
