Do timer events in Delphi happen in their own thread?

When a Delphi timer executes, is it not in the main thread?

procedure TMainForm.MyTimerTimer(Sender: TObject);
begin
      MyModalDialog.StatusText.BeginUpdate;
      MyModalDialog.StatusText.Text := 'timer fired...';
      MyModalDialog.StatusText.EndUpdate;
end;

I am wondering if crashes here are due to updating the GUI elements outside of the main thread.

The timer event handler execute in the context of the thread having created it. Usually it is the main thread but you can create a timer within any thread.

The timer will execute on the main thread. No need to worry about using Synchronize().
