Generic callback for text-input-field

Hey,

I have several text-input-fields defined and want to use a callback to
fill them. I would like to write a generic callback so that I don't
need to defun a callback for every single textfield. Is there maybe a
way to pass an own argument to the callback then those defined via
callback-type?

Best Regards,
Phil

Re: Generic callback for text-input-field

Hi Martin,

thank you for the hint. I already used the :callback-type :element.
But your hint gave me another idea how to solve it. I thought I needed
to get the name of my defined text-input-pane to set the new text, but
via the text accessor I just need the element itself.

Slowly my experience grows ;-)

Thank you,
Phil

Re: Generic callback for text-input-field

It might be worth looking into alternative values for :callback-type - that might give you the context that your callback requires.

Hey,

I think that I need your help again understanding callbacks. I have
several text-input-panes defined like this:

(text-pane-invoice-no capi:text-input-pane
:buttons '(:ok t)
:callback 'tdi++callback
:callback-type :element
:accessor text-pane-invoice-no)

I don't want to define an own callback function for every pane. But I
need to pass something like a key to the callback function.

I have something like this in mind:

(defun tdi++callback (element key)
(cond ((eq key :a)
....)))

I don't see how I can achieve that or if it is possible at all. And all
the possiblities at
http://www.lispworks.com/documentation/lw61/CAPRM/html/capiref-26.htm
confuses me bit.

Any Ideas?

Best regards,
Phil
