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.

Learning about lists

In this section, we are going to explore list controls in FMX, specifically, two components that implement list controls: TListBox and TListView. We'll learn when to favor one over the other and how to master their powerful features.

List controls (a concept usually distinct from grids) are very important in almost every application, but it is especially true that lists are the most frequently used way to deliver a large amount of data to the user on mobile platforms. Screens of mobile devices are usually smaller and the interaction is usually not mediated by a high-precision device (a mouse or a physical keyboard, for instance). Especially on mobile phones, it is quite natural to interact with the screen with a finger while holding the device with the same hand, making it naturally comfortable to consume information in the form of lists of items instead of grids with bi-directional scrolling.

The importance of list controls is assumed on mobile platforms, in...
