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.

Drawer mode

A drawer is a container for other controls that is generally not visible and can be activated by sliding one edge of a touchscreen from the outside to the inside of the screen. This triggers a gesture that will bring the drawer (now visible) in the current view by following the user's finger on the screen. It is a very common UI element as it adds some available space for UI controls without losing focus on the main content of the current view and without permanently stealing space for other controls. A typical usage is for menus or navigational items that the user can use to change/tweak the current view's content or switch to another view of your application.

Apart from a gesture, it is usually associated with a button you can press to trigger an animation mimicking the gesture behavior. It is not mandatory, but most people will look for a button with the hamburger icon (three horizontal lines stacked up, or three bullets stacked up) that is now universally...
