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.

Binding a field value to a property  TLinkPropertyToField

Consider the following scenario: we have a dataset (EmployeeData), a corresponding TBindSourceDB component (EmployeeBindSourceDB), and a TText component (the Text1 component). We want to bind the Text1.Text component property to the FirstName field of the dataset.

In the following screenshot, you can see the LiveBindings Designer tool window showing the bindable members of the TBindSourceDB and TText instances. The New LiveBinding dialog shows that the TLinkPropertyToField entry has been selected here:

Figure 6.5

Here, we can add a TBindingsList component to the form, start the component's editor (by double-clicking on it), add a new binding, and select the TLinkPropertyToField entry from the list (the previous screenshot shows the New LiveBinding dialog with the TLinkPropertyToField entry selected). The IDE will add a new LiveBinding object named...
