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.

Understanding multithreading

In Chapter 9, Building Responsive UIs, we talked about achieving responsiveness with visual meaning. In this chapter, we are going to discuss the particular ability of an application to look responsive to the user even when some time-consuming or computationally heavy operation is ongoing.

In this section, we will learn about the thread safety of UI frameworks. We will also learn how to distinguish between synchronous and asynchronous code execution. This will also need a discussion about synchronization techniques to mix and merge the two approaches.

If you are an experienced programmer, you will surely have been in situations where the UI of your applications seemed to freeze because of some heavy computation (long loops, network calls, or other I/O operations). The general behavior is to have a blank window or a frozen one, and the user has no choice other than killing the application or patiently waiting for the operation to complete, even if the application...
