Mastering Delphi Programming: A Complete Reference Guide

By: Primož Gabrijelčič

Overview of this book

Delphi is a cross-platform Integrated Development Environment (IDE) that supports rapid application development for most operating systems, including Microsoft Windows, iOS, and now Linux with RAD Studio 10.2. If you know how to use the features of Delphi, you can easily create scalable applications in no time. This Learning Path begins by explaining how to find performance bottlenecks and apply the correct algorithm to fix them. You'll brush up on tricks, techniques, and best practices to solve common design and architectural challenges. Then, you'll see how to leverage external libraries to write better-performing programs. You'll also learn about the eight most important patterns that'll enable you to develop and improve the interface between items and harmonize shared memories within threads. As you progress, you'll also delve into improving the performance of your code and mastering cross-platform RTL improvements. By the end of this Learning Path, you'll be able to address common design problems and feel confident while building scalable projects. This Learning Path includes content from the following Packt products: Delphi High Performance by Primož Gabrijel?i? Hands-On Design Patterns with Delphi by Primož Gabrijel?i?

Summary

While this chapter focused on a single topic, it was still quite diverse. You've learned everything about the TThread class, which is a basis for all multithreading code in Delphi. Even the task-based approach that we'll explore in the next chapter uses TThread as a basic building block.

I have shown three different ways of creating a TThread-based, multithreading solution. A program can take complete ownership of a thread so that it is created and destroyed by the owner. This approach is best used when a thread implements a service, as in such cases the main program knows best when the service is needed.

Another way, more appropriate for background calculations, is FreeOnTerminate mode. With this approach, a thread object is immediately destroyed when a thread's Execute function exits. The thread owner can set up an OnTerminate event to catch this...
