Overview of this book

Delphi is a cross-platform Integrated Development Environment (IDE) that supports rapid application development for Microsoft Windows, Apple Mac OS X, Google Android, and Apple iOS. It helps you to concentrate on the real business and save yourself the pain of wandering amid GUI widget details, or having to tackle inter-platform incompatibilities. It also has a wide range of drag-and-drop controls, helping you code your business logic into your business model, and it compiles natively for desktop and mobile platforms. This book will teach you how to design and develop applications, deploy them on the cloud platform, and distribute them within an organization via Google Play and other similar platforms. You will begin with the basics of Delphi and get acquainted with JSON format strings, XSLT transformations, unicode encodings and various types of streams. We then move on to more advanced topics such as developing higher-order functions and using enumerators and RTTI. You will get an understanding of how Delphi RTL functions and how to use FireMonkey in a VCL application. We will then cover topics such as multithreading, using the parallel programming library and putting Delphi on a server. We will also take a look at the new feature of WebBroker Apache modules and then ride the mobile revolution with FireMonkey. By the end of the book, you will be able to develop and deploy cross-platform applications using Delphi .

A TListBox component contains a list of TListBoxItem, and a TListBox item is a TStyledControl descendant. This means that every single item in a TListBox component can be styled! This feature opens a huge set of new possibilities regarding the use of the control.

Getting ready

In this recipe, you'll see a set of styled TListBoxItem components that when added to TListBox, changes its appearance completely. Let's say you have a listbox containing a log of events that happened in a monitored remote system. Some events are simply informative, while other events can denote a malfunction. Different kinds of events are shown with different graphics in the listbox. Here are the events...
