XtSetSensitive(3)		 XT FUNCTIONS		     XtSetSensitive(3)

NAME
       XtSetSensitive, XtIsSensitive - set and check a widget's	sensitivity
       state

SYNTAX
       void XtSetSensitive(Widget w, Boolean sensitive);

       Boolean XtIsSensitive(Widget w);

ARGUMENTS
       sensitive Specifies a Boolean value that	indicates whether the widget
		 should	receive	keyboard and pointer events.

       w	 Specifies the widget.

DESCRIPTION
       The XtSetSensitive function first calls XtSetValues on the current wid-
       get with	an argument list specifying that the sensitive field should
       change to the new value.	 It then recursively propagates	the new	value
       down the	managed	children tree by calling XtSetValues on	each child to
       set the ancestor_sensitive to the new value if the new values for sen-
       sitive and the child's ancestor_sensitive are not the same.

       XtSetSensitive calls XtSetValues	to change sensitive and	ancestor_sen-
       sitive.	Therefore, when	one of these changes, the widget's set_values
       procedure should	take whatever display actions are needed (for example,
       greying out or stippling	the widget).

       XtSetSensitive maintains	the invariant that if parent has either	sensi-
       tive or ancestor_sensitive False, then all children have	ancestor_sen-
       sitive False.

       The XtIsSensitive function returns True or False	to indicate whether or
       not user	input events are being dispatched.  If both core.sensitive and
       core.ancestor_sensitive are True, XtIsSensitive returns True; other-
       wise, it	returns	False.
