LINKABLE TAGS (BOZZA)
------------------------------------------------------------------------------

If you want to create a [popup window] to control
many items (one at a time) linkable [tags] would be
very useful. A linkable [tag] (named A, for
example) has the ability to be linked to another
[tag] (named B, for example), so A and B have
always the same value. If you assign a new value to
A the same value is assigned to B; the same if you
assign a value di B: that value is written to A
also. To build a [popup window] to control many
items two linkable tags would be used: * a tag (Status)
that will be linked to the tag that provide the
status of the item to control; * a tag (Command)
that will be linked to the tag that send commands
to the item to control. Before to show the [popup
window] to control the item 21 (for example) a
piece of [code] have to link the tag; for example:
Status.linkTo( Item21_Status ); Command.linkTo(
Item21_Command ); ItemControlPopup.show(); A
linkable [tag] can be linked to a single [tag] at a
time. Linkable [tags] are normally defined in the
[User domain] (for a purpose like in the example
above).
