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.

Filling items with data

Let's say we have prepared our TListView component with a dynamic appearance so that it can host multiple values on each item of the list. In the visual LiveBindings Designer, we can now see more bindable entries within the ListView1 element that match the Items.<ItemAppearanceElement> naming pattern. The LinkListControlToField binding can hold several expressions to be used in different parts of the list control:

  • FieldName and CustomFormat are useful when you need a simple binding across the data source and the list view, generally for addressing Items.Text (not many item appearance elements). The CustomFormat property is referred to when FieldName is specified.
  • FillExpressions determines how each item is filled with data. If you have multiple item appearance elements to fill, you'll need an expression for each. For each item, you must specify a ControlMember instance, so that you can address the item&apos...
