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.

Defining the fader stand

Back to our example: the fader stand is very basic but will add a nice fade in/out transition when showing/hiding the FrameStand to the user.

It is implemented using a TLayout component whose Align property has been set to the Contents value, filling the Parent object it will be associated with. No children with a StyleName container have been added so, as we have seen, we can expect the frame to be parented to the stand itself, using the aligning strategy of the frame (considering its Align, Anchors, and Margins properties and the like).

Two animations (TFloatAnimation instances, precisely) have been added to the TLayout component:

  • OnShow_FadeIn: This transitions the Opacity property of its parent (TLayout) from value 0 to value 1 with a duration of 400 milliseconds and a Quadratic interpolation. TLayout implementing the stand is basically the most outer element of the framestand composition and, due to the behavior of the...
