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.

The Multi-Device Preview window

Given that FMX and the Delphi IDE allow us to design views with device-specific variations, it may be challenging to keep everything under control. A very significant aid for this is provided by the Multi-Device Preview IDE tool window, located in the same tab control of Project Manager in the IDE window.

In a single spot, you can have a rendering of the current form against a number of selected devices (against the fact that you can design only one view at the time).

The following screenshot shows the Multi-Device Preview window with the example seen in the previous section:

The preceding screenshot, where the Multi-Device Preview window has been undocked from its original position, shows how the IDE is capable, in real time at design time, of previewing how the specific views will look like at runtime (the yellow-white checkmark on the upper-left corner of the first two previews is there to indicate that those are actually created views while...
