Author: dteske Date: Tue Jun 4 03:30:44 2013 New Revision: 251361 URL: http://svnweb.freebsd.org/changeset/base/251361 Log: Similar to r251236, r251242, and r251244. Introduce new function-pair to dialog(1) API in dialog.subr responsible for retrieving menu-choice data (for the --menu widget). Add f_dialog_menuitem_store()/f_dialog_menuitem_fetch() for storing and retrieving the menuitem (not the tag) from a --menu widget result. The dialog --menu widget returns the `tag' from the tag/item pair of choices for a menu list. Because the menu list is often local to the function that is displaying it, the ability to dereference this into the item is not possible unless you use a global. This changes things so the function (upon successful return of dialog) dereferences the tag into the item and stores it for later retrieval using these functions. NOTE: Tags are dereferenced into items using f_dialog_menutag2item().
