Hi Rodrigo,

every form can be a mdi child of any lazarus control with 2 lines of
code:

Code: [Select]procedure TForm1.ButtonAdminClick(Sender: TObject);
begin
  windows.SetParent(form7.Handle, panel2.Handle);
  SendMessage(form7.Handle, WM_NCACTIVATE, WPARAM(True), 0);
  form7.left := 10;
  form7.Top := 10;
  form7.show;
  form7.SetFocus;
end;    
The parent is panel2.Handle - the child is form7. This will only work
on windows...
