jQuery Datepicker with text input that doesn't allow user input

Question

How do I use the jQuery Datepicker with a textbox input:

$("#my_txtbox").datepicker({
  // options
});

that doesn't allow the user to input random text in the textbox. I want the Datepicker to pop up when the textbox gains focus or the user clicks on it, but I want the textbox to ignore any user input using the keyboard (copy & paste, or any other). I want to fill the textbox exclusively from the Datepicker calendar.

Is this possible?

jQuery 1.2.6
Datepicker 1.5.2

You should be able to use the readonly attribute on the text input, and jQuery will still be able to edit its contents.

<input type='text' id='foo' readonly='true'>
