What is the method of using multi-threading in Delphi?

There are a few different ways to use multi-threading in Delphi.

1. Using the TThread class: TThread is a base class for multithreading provided in Delphi, you can inherit from TThread class and implement the Execute method to create your own thread. Write the thread’s execution code inside the Execute method. You can start the thread by calling the Start method and terminate it by calling the Terminate method.
2. Using AnonymousThread: The System.Threading unit in Delphi provides the AnonymousThread class, which allows the creation of threads using anonymous methods. You can create an anonymous thread using the TThread.CreateAnonymousThread method and start the thread using the TThread.Start method.
3. By utilizing the Parallel library in Delphi, the System.Threading unit allows for easy parallel programming. The Parallel library offers methods such as Parallel.For and Parallel.ForEach to execute loops and traversals in parallel.
4. Using OmniThreadLibrary: OmniThreadLibrary is an open-source multi-threading library that can be used in Delphi. It offers advanced multi-threading capabilities such as task scheduling and message passing.

This is a common method for using multi-threading in Delphi, you can choose the appropriate method based on specific requirements for multi-threaded programming.
