[mcclim-devel] Subclassing text-field?

[Yoel Jacobsen]

I would like to have a numeric-only text-field. I want it to return
numbers with gadget-value, and to be able to setf it with numbers (and
not strings). Is subclassing text-field (and text-field-pane?) and
defining gadget-value and (setf gadget-value) the solution? If so, it
seems to be more complicated than I thought.

Any idea/help/example?

Thanks,
  Yoel
