Delphi Cookbook - Second Edition

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 FireMonkey in a VCL application


As you probably know, VCL is incompatible with FireMonkey. What does this mean? Embarcadero explains in the DocWiki:

"FireMonkey (FMX) and the Visual Component Library (VCL) are not compatible and should not be used together in the same module. That is, a module should be exclusively one or the other, either FireMonkey or VCL. The incompatibility is caused by framework differences between FireMonkey (FMX) and VCL."

However, there is still something that can be done to use FireMonkey functionalities in a VCL application.

It's very probable that a VCL application could gain benefits by using some components or functionalities present only in the FireMonkey framework. So what could be the solution? One solution is to create a Windows DLL that contains all the FireMonkey code and exposes a set of raw functions to access them. Then, the VCL application can load the DLL and call the exposed functions. Let's see this in action.

This recipe requires familiarity...
