NSSystemDefined, NSApplicationDefined, or
NSPeriodic
- (int)
data2;
Availability: OpenStep
Returns the 'data2' item associated with the event.

NSSystemDefined, NSApplicationDefined, or
NSPeriodic
- (float)
deltaX;
Availability: MacOS-X 10.0.0
Returns the movement of the mouse on the X axis.
This method is only valid for NSMouseMoved,
NS*MouseDragged and NSScrollWheel events,
otherwise it will raise an
NSInternalInconsistencyException.
- (float)
deltaY;
Availability: MacOS-X 10.0.0
Returns the movement of the mouse on the Y axis.
This method is only valid for NSMouseMoved,
NS*MouseDragged and NSScrollWheel events,
otherwise it will raise an
NSInternalInconsistencyException.
- (float)
deltaZ;
Availability: MacOS-X 10.0.0
Returns the movement of the mouse on the Z axis.
This method is only valid for NSMouseMoved,
NS*MouseDragged and NSScrollWheel events,
otherwise it will raise an
NSInternalInconsistencyException.
The value returned is 0.0 in most cases.
- (unsigned int)
deviceID;
Availability: Not in OpenStep/MacOS-X
