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.

Parameters

[in]

axisName

The name of the device axis to be tested

Returns

The position of the device for the specified axis

void setDevicePosition	(	const int	position,
		const unsigned short int	axis
	)

Sets the position of the device for the specified axis.

Parameters
