+The Sme object is the base class for all menu entries.  While this
+object is mainly intended to be subclassed, it may be used in a menu to
+add blank space between menu entries.

+The resources associated with the SmeLine object are defined in this

+There are no new resources added for this class, as it picks up all its
+resources from the RectObj class.

+Subclassing the Sme Object
+.IN "Sme object" "subclassing" "@DEF"
+.LP
+.sp
+To Create a new Sme object \fIclass\fP you will need to define three class methods.
+These methods allow the SimpleMenu to highlight and unhighlight the
+menu entry as the pointer cursor moves over it, as well as notify the
+entry when the user has selected it.  All of
+these methods may be inherited from the Sme object, although the default
+semantics are not very interesting.
+.IP \fBHighlight\fP(\|) 1i
+.IN "Sme object" "Highlight method"
+Called to put the menu entry into the highlighted state.
+.IP \fBUnhighlight\fP(\|) 1i
+.IN "Sme object" "Unhighlight method"
+Called to return the widget to its normal (unhighlighted) state.
+.IP \fBNotify\fP(\|)
+.IN "Sme object" "Notify method"
+Called when the user selects this menu entry.
+.LP
+.sp
+Other then these methods, creating a new object
+is straight forward.  Here is some information that may help you
+avoid some common mistakes.
+.IP 1) 3n
+Objects can be zero pixels high.
+.IP 2) 3n
+Objects draw on their parent's window, therefore the Drawing dimensions
+are different from those of widgets.  For instance, y locations vary
+from \fBy\fP to \fBy + height\fP, not \fB0\fP to \fBheight\fP.
+.IP 3) 3n
+XtSetValues calls may come from the application while the Sme is highlighted,
+and if the SetValues method returns True, will result in an expose event.
+The SimpleMenu may later call the menu entry's \fBunhighlight\fP
+procedure.  However, due to the asynchronous nature of
+X, the expose event generated by \fBXtSetValues\fP will come \fIafter\fP
+this unhighlight.
+.IP 4) 3n
+Remember that your subclass of the Sme does not own the
+window.  Share the space with other menu entries, and refrain
+from drawing outside the subclass's own section of the menu.
