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 spec-
	      ify 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 compati-
	      bility 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  compati-
	      bility and will be removed in a future version.
