XT FUNCTIONS                                  XtSetSensitive(3xt)



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

SYNTAX
     cc [ flag... ] file... -lXt [ library... ]

     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 widget 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 chil-
     dren tree by calling XtSetValues on each child to set the
     ancestor_sensitive to the new value if the new values for
     sensitive and the child's ancestor_sensitive are not the
     same.

     XtSetSensitive calls XtSetValues to change sensitive and
     ancestor_sensitive.  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 sensitive or ancestor_sensitive False, then all chil-
     dren have ancestor_sensitive 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; otherwise, it returns False.
