A base class for deriving new Sensor-types from.

Instance Methods | [hide private]

__init__(self, interval=1000) Create a new sensor which updates after the given interval. | source code

get_interval(self) Get the update-interval time for this Sensor. | source code

set_interval(self, ms) Set the update-interval time for this Sensor and start it. | source code

stop(self) Immediately stop this sensor and emit the "sensor_stopped"-signal. | source code

on_update(self) Override this handler in subclasses to implement your calculations and update the Sensor's attributes. | source code

__timeout(self) The timeout function. | source code

Method Details | [hide private]

### __init__(self, interval=1000)
(Constructor)

source code

Create a new sensor which updates after the given interval.

Overrides: gobject.GObject.__init__

### on_update(self)

source code

Override this handler in subclasses to implement your calculations and update the Sensor's attributes. Must return True to emit a signal which can then be handled within the screenlets, returning False causes the Sensor to be stopped..

### __timeout(self)

source code

The timeout function. Does nothing but calling the on_update handler and emitting a signal if the handler returned True.

Class Variable Details | [hide private]

### __gsignals__

Value:

      dict(sensor_updated= (gobject.SIGNAL_RUN_FIRST, gobject.TYPE_NONE, ())
      , sensor_stopped= (gobject.SIGNAL_RUN_FIRST, gobject.TYPE_NONE, ()))
