NSEventMBS.absoluteX as Integer
Function:
Reports the absolute x coordinate of a pointing device on its tablet at full tablet resolution.
Notes:
For the coordinate to be valid, the receiver should represent an event generated by a tablet pointing device (otherwise 0 is returned). This method is valid only for mouse events with a subtype of NSTabletPointEventSubtype and for events of type NSTabletPoint. Use this value if you want to scale from tablet location to screen location yourself; otherwise use the class method mouseLocation or the instance method locationInWindow.
Available in Mac OS X v10.4 and later.

NSEventMBS.absoluteZ as Integer
Function:
Reports the absolute z coordinate of pointing device on its tablet at full tablet resolution.
Notes:
For the coordinate to be valid, the receiver should represent an event generated by a tablet pointing device (otherwise 0 is returned). The z coordinate does not represent pressure. It registers the depth coordinate returned by some tablet devices with wheels; if the device is something other than these, 0 is returned. This method is valid only for mouse events with a subtype of NSTabletPointEventSubtype and for events of type NSTabletPoint.

NSEventMBS.characters as string
Function:
Returns the characters associated with the receiving key-up or key-down event.
Notes:
These characters are derived from a keyboard mapping that associates various key combinations with Unicode characters. Raises an NSInternalInconsistencyException if sent to any other kind of event object.
This method returns an empty string for dead keys, such as Option-e. However, for a key combination such as Option-Shift-e this method returns the standard accent ("'").

NSEventMBS.charactersIgnoringModifiers as string
Function:
Returns the characters generated by the receiving key event as if no modifier key (except for Shift) applies.
Notes:
Raises an NSInternalInconsistencyException if sent to a nonkey event.
This method returns the non-modifier key character pressed for dead keys, such as Option-e. For example, Option-e (no shift key) returns an "e" for this method, whereas the characters method returns an empty string.
This method is useful for determining "basic" key values in a hardware-independent manner, enabling such features as keyboard equivalents defined in terms of modifier keys plus character keys. For example, to determine if the user typed Alt-S, you don't have to know whether Alt-S generates a German double ess, an integral sign, or a section symbol. You simply examine the string returned by this method along with the event's modifier flags, checking for "s" and NSAlternateKeyMask.

NSEventMBS.clickCount as Integer
Function:
Returns the number of mouse clicks associated with the receiver, which represents a mouse-down or mouse-up event.
Notes:
Raises an NSInternalInconsistencyException if sent to a nonmouse event.
Returns 0 for a mouse-up event if a time threshold has passed since the corresponding mouse-down event. This is because if this time threshold passes before the mouse button is released, it is no longer considered a mouse click, but a mouse-down event followed by a mouse-up event.
The return value of this method is meaningless for events other than mouse-down or mouse-up events.

Notes:
The value returned by this method is dependent on the event type, and is defined by the originator of the event. Raises an NSInternalInconsistencyException if sent to an event not of type NSAppKitDefined, NSSystemDefined, NSApplicationDefined, or NSPeriodic.

NSEventMBS.deltaY as Double
Function:
Returns the y-coordinate change for a scroll wheel, mouse-move, or mouse-drag event.
Notes:
The behavior of this method may seem counter-intuitive: as the mouse moves up the screen, the value is negative; and as it moves down the screen, the value is positive. The reason for this behavior is that NSEvent computes this delta value in device space, which is flipped, but both the screen and the window's base coordinate system are not flipped.

NSEventMBS.hasPreciseScrollingDeltas as boolean
Function:
Returns whether there are precise scrolling deltas available.
Notes:
Returns true if precise scrolling deltas are available; false otherwise.
This method is valid for NSScrollWheel events. A generic scroll wheel issues rather coarse scroll deltas. Some mice and trackpads provide much more precise delta. This method determines how the values of the scrollingDeltaX and scrollingDeltaY should be interpreted.

NSEventMBS.isDirectionInvertedFromDevice as boolean
Function:
Returns whether the user has changed the device inversion.
Notes:
This method valid for NSEventScrollWheel and NSEventTypeSwipe events. The user may choose to change the scrolling behavior such that it feels like they are moving the content instead of the scroll bar.
To accomplish this, deltaX and deltaY and scrollingDeltaX and scrollingDeltaY values are automatically inverted for NSEventScrollWheel events according to the user's preferences.
The direction of fluid swipes matches the direction of scrolling and as such for NSEventTypeSwipe events gestureAmount is inverted. However, for some uses of NSEventScrollWheel and NSEventTypeSwipe events, the behavior should not respect the user preference. This method allows you to determine when the event has been inverted and compensate by multiplying -1 if needed.
Available in OS X v10.7 and later.
