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.

Custom Wireframe component

The source code of FireMonkey is very helpful in understanding how the library works, but we can also use it as a template to build our own custom components. Rendering a cube is not a lot of code but using a similar approach, we could create a custom wireframe component that is similar to TStrokeCube. We can just implement the Render method differently and paint arbitrary lines, the coordinates of which are stored internally within our component.

Create a new Delphi multi-device application and select 3D Application as the application type. Save the main form unit as uFormWireframe and the whole project as WireframeTest. Rename the form as FormWireframe. Save all.

Add a new unit to the project and save it as uWireframe. Here we are going to implement a custom component called TWireframe that, similarly to TStrokeCube, inherits from the TControl3D class...
