Delphi Cookbook - Second Edition

By: Daniele Teti

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 .

Using master/details with LiveBindings


When you have a customer with his/her orders or an invoice with his/her items, you have a master/details (M/D) relationship. In this recipe, you will learn how to use the new LiveBindings technology to show an M/D relationship.

As explained in the Embarcadero wiki:

"LiveBindings is a data-binding feature supported by both the VCL and FireMonkey frameworks in RAD Studio. LiveBindings is an expression-based framework, which means it uses bindings expressions to bind objects to other objects or to dataset fields."

LiveBindings is a very nice technology and can be used in VCL applications also, but its main targets are FireMonkey applications. Indeed, it is the only way to do automatic data binding in the FireMonkey framework. If you don't know what LiveBindings is or what its strengths are, I suggest you stop here and read the article in the Embarcadero wiki at http://docwiki.embarcadero.com/RADStudio/en/LiveBindings_in_RAD_Studio.
