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.

TImageViewer is a simple component that can provide basic manipulation functionalities to the user. Basically, it shows an image (see the Bitmap property) in a scroll box so that if the image exceeds the viewer's dimensions, scrollbars will appear and the user will be able to pan the image (via the mouse or touch) to view a portion of it.

The image can also be scaled by setting the BitmapScale property (there is also support for user interaction on the desktop since the user can scale the bitmap by rolling the mouse wheel when the MouseScaling property is set to True). The component provides a convenient background for the picture (see the BackgroundFill property, which is implemented with a TBrush object – this means it has the same capabilities we covered for the Fill and Stroke properties of TShape descendants, previously in this book). There is also basic support to let the user change the actual content of the image (an OpenDialog...
