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.

Item appearances

Some of these item appearances are built-in and you can simply select one of them to change the layout of your TListView items. Different appearances can be set according to the item's type (header, footer, regular item, and edit item where the last one is a different version of the item used when TListView is put in Edit mode), and there is a registry (TAppearancesRegistry in the FMX.ListView.Appearances unit) so you can add your own if you like.

Back to our example, you can select the Text item in the Structure view (the type is TTextObjectAppearance) and change TextColor (or other Font properties) to configure how the text of the list item will be painted. You can configure almost any aspect of the text and it is fairly simple: text alignment (vertical and horizontal), text trimming, wrapping, and similar ones are all there. The following screenshot shows the Object Inspector window when the...
