NAME

       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 particular 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 particular
              button or Event::any (meaning any of the buttons).

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

       void Catch(EventType)
              Express interest in a particular type of event.  This function is  provided  solely  for  backward
              compatibility and will be removed in a future version.

       void CatchButton(EventType, int)
              Express  interest  in  a  particular type of button event for a specific button.  This function is
              provided 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
              compatibility 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
              provided solely for backward compatibility and will be removed in a future version.
