Signature

abort-exit-confirmer

Description

The function abort-exit-confirmer can be used to abort the exiting of a confirmer. It can be used in the ok-function of a confirmer, to abort the exit and return to the dialog.

If abort-exit-confirmer is called outside the exiting of a confirmer, it does nothing.

Examples

This example asks the user for a string. If the string is longer than 20 characters, it confirms with the user that they really want such a long string, and if they do not it returns to the dialog.

(capi:popup-confirmer
 (make-instance 'capi:text-input-pane)
 "New Name"
 :value-function 'capi:text-input-pane-text
 :ok-function 
 #'(lambda (value)
     (when (and (> (length value) 20)
                (not (capi:prompt-for-confirmation
                      "Name is very long. Use it?")))
       (capi:abort-exit-confirmer))
     value))
