ProcessMessages and application use

I need to know if using ProcessMessages, which allows me to use the entire application, is legal.

Pseudocode:

The button for calling the main thread is a search.

procedure ButtonOnClick;
begin
    var1 = ExecuteSearch();
end;    

function ExecuteSearch:Something;
begin
 thread.StartThread;
 while thread.Finished do
 Application.ProcessMessages;
 result := something;
end;

When I use this construct, I can click on other parts of my software and use it. But I do not know how this works. And if it's safe.
