pyudev.wx – wxPython integration

Wx integration.

MonitorObserver 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.MonitorObserver(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, Monitor
>>> from pyudev.wx import MonitorObserver
>>> context = Context()
>>> monitor = Monitor.from_netlink(context)
>>> monitor.filter_by(subsystem='input')
>>> observer = MonitorObserver(monitor)
>>> def device_event(event):
...     print('action {0} on device {1}'.format(event.device.action, event.device))
>>> observer.Bind(EVT_DEVICE_EVENT, device_event)
>>> monitor.start()

This class is a child of wx.EvtHandler.

New in version 0.17.

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.

Events

MonitorObserver posts the following event:

pyudev.wx.EVT_DEVICE_EVENT

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

class pyudev.wx.DeviceEvent

Argument object for EVT_DEVICE_EVENT.

device

The Device object that caused this event.

Use action to get the type of event.

Deprecated members

action

A unicode string containing the action name.

Deprecated since version 0.17: Will be removed in 1.0. Use action instead.

Deprecated API

class pyudev.wx.WxUDevMonitorObserver(monitor)

An observer for device events integrating into the wx mainloop.

Deprecated since version 0.17: Will be removed in 1.0. Use MonitorObserver instead.

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.

Events

WxUDevMonitorObserver posts the following events in addition to EVT_DEVICE_EVENT:

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.

Deprecated since version 0.17: Will be removed in 1.0.

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.

Deprecated since version 0.17: Will be removed in 1.0.

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.

Deprecated since version 0.17: Will be removed in 1.0.

pyudev.wx.EVT_DEVICE_MOVED

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

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.

Deprecated since version 0.17: Will be removed in 1.0.

device

The Device object that caused this event.
