title: How to force a focus on a component before the Form is shown
body: <p>I have to show (with <code>ShowModal</code>) a Form with many <code>TEdit</code> but I want to force the focus on a <code>TEdit</code>, but not always the same, depending on the context.</p>
  
  <p>I can't use <code>SetFocus</code> before the <code>ShowModal</code> (because the Form is not activate) and use the component <code>Name</code> or <code>Tag</code> is not convenient in my application.
  Do you have an idea ?</p>
