Detailed Description

Input device state.

MDeviceState is a generic event class for input devices. Input device classes (such as MPxMidiInputDevice) are responsible for converting specific event types to an MDeviceState which Maya understands.

Examples:

jlcVcrDevice.cpp.

#include <MDeviceState.h>
