Delphi Programming Projects

Overview of this book

Delphi is a cross-platform programming language and software development kit that supports rapid application development for Microsoft Windows, Apple Mac OS X, Android, and iOS. With the help of seven practical projects, this book will guide you through the best practices, Delphi Run-Time Library (RTL) resources, and design patterns. Whether you use the Visual Component Library (VCL) or FireMonkey (FMX) framework, these design patterns will be implemented in the same way in Delphi, using Object Pascal. In the first few chapters, you will explore advanced features that will help you build rich applications using the same code base for both mobile and desktop projects. In addition to this, you’ll learn how to implement microservice architecture in Delphi. As you get familiar with the various aspects of Delphi, you will no longer need to maintain source code for similar projects, program business rules on screens, or fill your forms with data access components. By the end of this book, you will have gained an understanding of the principles of clean code and become proficient in building robust and scalable applications in Delphi.

Sharing screens

Now that we have built part of the desktop application, we need to start developing the Android mobile application. In it, we will use the camera to send a newly taken photo, remotely and automatically, to the desktop.

Sending data from a mobile to a desktop

Start a new project in Delphi by following these steps:

  1. Navigate to File | New | Multi-Device Application - Delphi.
  1. Select Blank Application:
  1. Add the TTetheringManager component.
  2. Add the TTetheringAppProfile component.
  3. In the AppProfile, go to the Group property; set the same value that you set for the desktop profile. In our case, we used the group Packt:
  1. Set the Manager property for the TetheringManager1 that was added to the form.
  2. In Manager...
