n Delphi, you can use the TThread class to create and manage threads. To create a thread, you need to define a new class that descends from TThread and overrides the Execute method. The Execute method is where you put the code that you want to run in the thread.
Here is an example of how to create and start a thread in Delphi

type TWorkerThread = class(TThread) protected procedure Execute; override; end; procedure TWorkerThread.Execute; begin //This is the code that runs in the thread //You can put any code you want here ... end; //To create and start the thread var WorkerThread: TWorkerThread; begin WorkerThread := TWorkerThread.Create(False); WorkerThread.Start; end; |
In the example above, the TWorkerThread class is derived from TThread and overrides the Execute method. The Execute method is where you put the code that you want to run in the thread. The TThread.Create method is called with a parameter of False, which indicates that the thread is created in a suspended state. The Start method is then called to start the thread.
You can also pass parameters to the thread by using constructor parameters and storing the values in fields of the thread class. For example

type TWorkerThread = class(TThread) private FParameter: Integer; protected procedure Execute; override; public constructor Create(AParameter: Integer); end; constructor TWorkerThread.Create(AParameter: Integer); begin inherited Create(False); FParameter = AParameter; end; procedure TWorkerThread.Execute; begin //Use the parameter in the thread ... end; //To create and start the thread var WorkerThread: TWorkerThread; begin WorkerThread := TWorkerThread.Create(123); WorkerThread.Start; end; |
