RX has a property 'DirectInput' for its TDateEdit and friends. 
It controls whether the user can type or is forced to use the button (dialog).

If you have DirectInput, then ReadOnly should disallow typing and also disallow 
the use of the button.

Using enabled for 'readonly' is not correct, since the control is shown
differently (grayed-out) when it is not enabled, and that is not the
intention.
