   #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.
