Returns an initialised evdev object.

  • Returns: An initialised evdev object.

evdev object

evdevObject::open( path, callback( evdevObject, error ) )

Open an evdev device, associate it to this object, and fire the provided callback upon completion.

The parameters passed to the provided callback function are evdevObject which is a reference to the evdev object, and error which will be an error string in the case of an error, or undefined on success.

  • Returns: A reference to itself.

evdevObject::data( evdevEvent )

A virtual method of the evdevObject. Reimplement it to handle evdevEvents. It can be ignored, but if you ignore it, you might as well not use this module at all.

evdevObject::closed( evdevObject )

A virtual method of the evdevObject. Reimplement it to react to the device being closed. Otherwise it can be ignored.
