Object is never instantiated.
Its sole purpose is as a supporting superclass for other
widget classes.
Classes
The class pointer is objectClass.
The class name is Object.
New resources
The following table defines a set of widget resources used by the programmer
to specify data. The programmer can also set the resource values for the
inherited classes to set attributes for this widget. To reference a
resource by name or by class in a .Xdefaults file,
remove the ``XmN'' or ``XmC'' prefix and use the
remaining letters. To specify one of the defined
values for a resource in a .Xdefaults file,
remove the ``Xm'' prefix and use the remaining letters
(in either lowercase or uppercase, but include any
underscores between words).
The codes in the access column indicate if the given resource can be
set at creation time (C),
set by using XtSetValues (S),
retrieved by using XtGetValues (G), or is not applicable (N/A).
