Sensor - describe input interest

SYNOPSIS

       #include <InterViews/sensor.h>

DESCRIPTION

       A sensor specifies a set of input events to catch.

PUBLIC OPERATIONS

       Sensor()
              Create  a  new sensor that initially will not catch
              any events.

       virtual void motion(boolean)
              Specify the sensor should (parameter  is  true)  or
              should  not  (parameter  is  false)  catch  pointer
              motion events.

       virtual boolean motion()
              Return  whether  the  sensor  is  catching  pointer
              motion events.

       virtual void key(boolean)
              Specify  the  sensor  should (parameter is true) or
              should not  (parameter  is  false)  catch  keyboard
              events.

       virtual boolean key()
              Return  whether  the  sensor  is  catching keyboard
              events.

       virtual void button(boolean, PointerButton = Event::any)
              Specify the sensor should (parameter  is  true)  or
              should   not  (parameter  is  false)  catch  button
              events.  The pointer button may specify a  particu-
              lar   button  or  Event::any  (meaning  all  button
              events).

       virtual boolean button(PointerButton = Event::any)
              Return  whether  the  sensor  is  catching   button
              events.   The pointer button may specify a particu-
              lar button or Event::any (meaning any of  the  but-
              tons).

       virtual boolean caught(Event&)
              Return  whether  the  sensor  is catching the given
              event.

       void Catch(EventType)
              Express interest in a  particular  type  of  event.

              Express  interest  in  a  particular type of button
              event for a specific button.  This function is pro-
              vided solely for backward compatibility and will be
              removed in a future version.

       void Ignore(EventType)
              Remove interest in  a  particular  type  of  event.
              This  function is provided solely for backward com-
              patibility and will be removed in a future version.

       void IgnoreButton(EventType, int)
              Remove  interest  in  a  particular  type of button
              event for a specific button.  This function is pro-
              vided solely for backward compatibility and will be
              removed in a future version.
