Overview of this book

Delphi is the most powerful Object Pascal IDE and component library for cross-platform native app development. It enables building natively compiled, blazingly fast apps for all major platforms including Android, iOS, Windows, Mac, and Linux. If you want to build server-side applications, create web services, and have clear GUIs for your project, then this book is for you. The book begins with a basic primer on Delphi helping you get accustomed to the IDE and the Object Pascal language and will then quickly move on to advanced-level concepts. Through this book, we’ll help you understand the architecture of applications and will teach you the important concepts of the FireMonkey library, show you how to build server-side services, and enable you to interact with the Internet of Things. Towards the end, you will learn to integrate your app with various web services and deploy them. By the end of the book, you will be able to build powerful, cross-platform, native apps for iOS and Android with a single code base.

Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The TForm class, which is an ancestor to TFormSettings, is, in turn, inherited from the TComponent class."

A block of code is set as follows:

Application.Initialize; 
Application.CreateForm(TFormMain, FormMain);
Application.CreateForm(TFormSettings, FormSettings);
Application.Run;

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

const EL = #13; 

procedure TForm1.ButtonMultilineClick(Sender: TObject);
begin
ShowMessage('Welcome!' + EL + 'Good morning!');
end;

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "In the New Items window, make sure that the Delphi Projects node is selected, and double-click on the Console Application icon."
