The OpenNI::DeviceStateChangedListener class provides a means of registering for, and responding to when a device's state is changed.
onDeviceStateChanged is triggered whenever the state of a connected device is changed.
To use this class, you should write a new class that inherits from it, and override the onDeviceStateChanged method. Once you instantiate your class, use the OpenNI::addDeviceStateChangedListener() function to add your listener object to OpenNI's list of listeners. Your handler function will then be called whenever the event occurs. A OpenNI::removeDeviceStateChangedListener() function is also provided, if you want to have your class stop listening to these events for any reason.
virtual void openni::OpenNI::DeviceStateChangedListener::onDeviceStateChanged | ( | const DeviceInfo * | , |
DeviceState | |||
) | [pure virtual] |
Callback function for the onDeviceStateChanged event. This function will be called whenever this event occurs. When this happens, a pointer to a DeviceInfo object for the affected device will be supplied, as well as the new DeviceState value of that device.
