WxUDevMonitorObserver
(monitor)¶ An observer for device events integrating into the
wx
mainloop.This class inherits
EvtHandler
to turn device events into wx events:>>> from pyudev import Context, Device >>> from pyudev.wx import WxUDevMonitorObserver >>> context = Context() >>> monitor = Monitor.from_netlink(context) >>> monitor.filter_by(subsystem='input') >>> observer = WxUDevMonitorObserver(monitor) >>> def device_connected(event): ... print('{0!r} added'.format(event.device)) >>> observer.Bind(EVT_DEVICE_ADDED, device_connected) >>> monitor.start()
This class is a child of
wx.EvtHandler
.-
enabled
¶ Whether this observer is enabled or not.
If
True
(the default), this observer is enabled, and emits events. Otherwise it is disabled and does not emit any events.
