/*
* Method declared on Dialog.
*
* The main result is to set the preference field in a particular way,
* according to the particular button pressed, but without updating the
* underlying preferences node. Thus the effect of this method is to
* change the field in the display without making the new value visible
* to other fields. For th e new value to take effect it must be later
* stored into the preferences node by some oher action (typically the
* pressing of an Apply or OK button).
