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 widget with an argument list spec-ifying specifying
       ifying 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 ances-tor_sensitive ancestor_sensitive
       tor_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 children 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.
