pyudev.wx – wxPython integration

Wx integration.

WxUDevMonitorObserver integrates device monitoring into the wxPython mainloop by turing device events into wx events.

wx from wxPython must be available when importing this module.

New in version 0.14.

class pyudev.wx.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.

monitor

The Monitor observed by this object.

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.

Event constants

WxUDevMonitorObserver exposes the following events:

pyudev.wx.EVT_DEVICE_EVENT

Emitted upon any device event. Receivers get a DeviceEvent object as argument.

pyudev.wx.EVT_DEVICE_ADDED

Emitted if a Device is added (e.g a USB device was plugged). Receivers get a DeviceAddedEvent object as argument.

pyudev.wx.EVT_DEVICE_REMOVED

Emitted if a Device is removed (e.g. a USB device was unplugged). Receivers get a DeviceRemovedEvent object as argument.

pyudev.wx.EVT_DEVICE_CHANGED

Emitted if a Device was somehow changed (e.g. a change of a property). Receivers get a DeviceChangedEvent object as argument.

pyudev.wx.EVT_DEVICE_MOVED

Emitted if a Device was renamed, moved or re-parented. Receivers get a DeviceMovedEvent object as argument.

Event objects

action

A unicode string containing the action name.

device

The Device object that caused this event.

class pyudev.wx.DeviceAddedEvent

class pyudev.wx.DeviceRemovedEvent

class pyudev.wx.DeviceChangedEvent

class pyudev.wx.DeviceMovedEvent

Argument objects for EVT_DEVICE_ADDED, EVT_DEVICE_REMOVED, EVT_DEVICE_CHANGED and EVT_DEVICE_MOVED.

device

The Device object that caused this event.
