The presentation-based user interface style directly supported by
Dynamic Windows and CLIM generally seems to assume that an object and
its presentation reside on the same processor, since the presentation
maintains a reference to the object to which it refers. I need,
however, to provide a manipulable interface to *remote* objects (i.e.,
objects on other processors). None of the user interface software can
run on the remote processor; so I cannot, for example, simply run an X
screen off that processor.
Let's say I represent each remote object by its name (of type SYMBOL).
Is it safe, for all DW/CLIM purposes, to directly present an object name
(a SYMBOL) with the presentation type of the remote object's class
(which is a CLOS user-defined class)? Or must I define an entire shadow
hierarchy of "ambassador" presentation types (which eventually expand
into type SYMBOL), and present each object name with its corresponding
"ambassador" presentation type? Anyone have a better idea?
