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?

Delphi idioms – parallel programming

Delphi offers many tools to write multithreaded programs. As this is a book about patterns, not about parallel programming, I will not be able to go into much detail on that topic. Still, it is good to know which tools you have available so that you can do additional research in your own time.

In this introductory section, I will walk you through the Delphi tools that facilitate the writing of multithreaded applications. The DelphiThreading project from the Parallel programming in Delphi folder provides a simple example for every one of them.

A standard platform-independent way to create a new thread in Delphi is to create a descendant of a TThread class (implemented in the System.Classes unit) and override its Execute method. Delphi will use operating system functions to create a new thread and start the Execute...
