    Simple Thread Worker for delphi ( same as backgroundworker in C# )

    Hello there. I starting delphi ( free pascal ), I have confused how to doing background worker in delphi and this what I found this solution.

    This for unfreezing UI when executing long task.

    Add this before after type

    PHP Code:
    // =========== WORKER CLASS
    TMyWorkerThread = class(TThread)
     protected
       
    // the main body of the thread
       
    procedure Executeoverride;
     
    end;
    // =========== WORKER CLASS 

    then add this after implementation

    PHP Code:
    procedure TMyWorkerThread.Execute;


    var
    integer;
    begin
      i 
    := 0;
      while 
    100 do
      
    begin
        
    // play beep sound
        
    Form1.Label1.Caption := IntToStr(i);
        
    sleep(100); //refreshing cpu -- around 16 miliseconds
        // process pending messages might be in message queue
        
    i:= +1;
        
    //Application.ProcessMessages;

      
    end;
      
    //Here we do work
       //showmessage('aaaaaaaaaa');
      //When we exit the procedure, the thread ends.
      //So we don't exit until we're done.
    end


    And called it when button click or else

    PHP Code:
    TMyWorkerThread.Create(false);
