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 TImage component is very common in a lot of FMX applications. Basically, it is a container for MultiResBitmap and lets you render a graphic resource by selecting the most appropriate one for the device running your application. This means the scale factor that's selected to match MultiResBitmap only depends on the scale factor of the form where the TImage instance resides.

The main properties of this component are as follows:

  • MultiResBitmap: The value of this property will provide the actual content of the image. As we mentioned previously, this represents a very modern and effective way of handling graphic resources.
  • DisableInterpolation: When this property is set to False (the default) and you are in a situation where a bitmap is drawn to a target size greater than its actual size, you automatically get an interpolated version that smooths the picture to make it look better. If you set the value of this property to True, you will probably gain some...
