The !Address0 application provides a somewhat different user interface than the previous desribed components.
Except for the "Type" Stringset window gadget, which serves to select the kind of association (eg. home or office), changes of other window gadgets are done by dragging'n dropping from other applications' windows (per the special icon sprites named respectively "AdB" and "AdG")
To display and/or change the reffered data in the window (that is data managed by the !AddressB and !AddressG applications), the user can click on the "Details" action button respectively inside the "Identity" and "Geographic location" gadget groups;
Except for the ID fields, the displayed data field in the "Identity" and "Geographic location" gadget groups are built as a result of a message passing between the !Address0 application and one of the !AddressB/!AddressG applications. In case any of the latter applications is currently unreachable, then a mention like "Unreachable" is displayed instead in the relevant display fields.
