.IP \fIwidget_class\fP 1i
Specifies the widget class\*(Wc.
.IP \fI...\fP 1i
Specifies the variable argument list \*(Al.
.SH DESCRIPTION
The
.ZN XtCreatePopupShell
function ensures that the specified class is a subclass of
.ZN Shell
and, rather than using insert_child to attach the widget to the parent's
.IN "insert_child procedure"
children list, attaches the shell to the parent's pop-ups list directly.
.LP
A spring-loaded pop-up invoked from a translation table already must exist
at the time that the translation is invoked, 
so the translation manager can find the shell by name.
Pop-ups invoked in other ways can be created ``on-the-fly'' when
the pop-up actually is needed.
This delayed creation of the shell is particularly useful when you pop up
an unspecified number of pop-ups.
You can look to see if an appropriate unused shell (that is, not
currently popped up) exists and create a new shell if needed.
