Sir, try this:

procedure TForm1.Button1Click(Sender: TObject);
var
  plMDIFormX: TplMDIForm;
begin

  plMDIFormX:= TplMDIForm.Create(plMDIFormsPanel1);
  plMDIFormX.Parent := plMDIFormsPanel1;

  plMDIFormX.Visible:=true;
end;

or

procedure TForm1.Button1Click(Sender: TObject);
var
  plMDIFormX: TplMDIForm;
begin
  plMDIFormX:= plMDIFormsPanel1.NewMDIForm('test');
  plMDIFormsPanel1.AddMDIForm(plMDIFormX);

  plMDIFormX.Visible:=true;
end;

TplMDIForm.Create, "constructor"
register to the "parent" (a TplMDIFormsPanel)
the TplMDIForm....
