Since many ST-80 classes are subclasses of SompleDialog, this class
is provided here to allow easier porting of ST-80 code.
It does not (currently) provide much functionality and is NOT
compatible to the corresponding ST80 class; therefore, manual
changes have to be made to get those applications to run under ST/X.
(but at least, this enables you to fileIn that code and have a superclass
for them)
However, as time goes by, ST/X applications may be converted to use the
ApplicationModel / SimpleDialog framework as well.
Notice: this class was implemented using protocol information
from alpha testers and PD code - it may not be complete or compatible to
the corresponding ST-80 class. If you encounter any incompatibilities,
please forward a note to the ST/X team.
