DESCRIPTION
       The QTabletEvent class contains parameters that describe a Tablet
       event.

       Tablet Events are generated from a Wacom© tablet. Most of the time
       you will want to deal with events from the tablet as if they were
       events from a mouse, for example retrieving the position with x(), y(),
       pos(), globalX(), globalY() and globalPos(). In some situations you may
       wish to retrieve the extra information provided by the tablet device
       driver, for example, you might want to adjust color brightness based on
       pressure. QTabletEvent allows you to get the pressure(), the xTilt()
       and yTilt(), as well as the type of device being used with device()
       (see TabletDevice).

       A tablet event contains a special accept flag that indicates whether
       the receiver wants the event. You should call QTabletEvent::accept() if
       you handle the tablet event; otherwise it will be sent to the parent
       widget.

       The QWidget::setEnabled() function can be used to enable or disable
       mouse and keyboard events for a widget.

       The event handler QWidget::tabletEvent() receives all three types of
       tablet events. Qt will first send a tabletEvent and then, if it is not
       accepted, it will send a mouse event. This allows applications that
       don't utilize tablets to use a tablet like a mouse while also enabling
       those who want to use both tablets and mouses differently.

       See also Event Classes.

   Member Type Documentation
QTabletEvent::TabletDevice
       This enum defines what type of device is generating the event.

       QTabletEvent::NoDevice - No device, or an unknown device.

       QTabletEvent::Puck - A Puck (a device that is similar to a flat mouse
       with a transparent circle with cross-hairs).

       QTabletEvent::Stylus - A Stylus (the narrow end of the pen).

       QTabletEvent::Eraser - An Eraser (the broad end of the pen).

MEMBER FUNCTION DOCUMENTATION
QTabletEvent::QTabletEvent ( Type t, const QPoint & pos, const QPoint &
       globalPos, int device, int pressure, int xTilt, int yTilt, const
       QPair<int, int> & uId )
       Construct a tablet event of type t. The position of when the event
       occurred is given int pos and globalPos. device contains the device
       type, pressure contains the pressure exerted on the device, xTilt and
       yTilt contain device's degree of tilt from the X and Y axis
       respectively. The uId contains an event id.

       On Irix, globalPos will contain the high-resolution coordinates
       received from the tablet device driver, instead of from the windowing
       system.

       See also pos(), globalPos(), device(), pressure(), xTilt(), and
       yTilt().

QTabletEvent::QTabletEvent ( const QPoint & pos, const QPoint & globalPos, int
       device, int pressure, int xTilt, int yTilt, const QPair<int, int> & uId
       )
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

       Constructs a tablet event object. The position when the event occurred
       is is given in pos and globalPos. device contains the device type,
       pressure contains the pressure exerted on the device, xTilt and yTilt
       contain the device's degrees of tilt from the X and Y axis
       respectively. The uId contains an event id.

       On Irix, globalPos will contain the high-resolution coordinates
       received from the tablet device driver, instead of from the windowing
       system.

       See also pos(), globalPos(), device(), pressure(), xTilt(), and
       yTilt().

void QTabletEvent::accept ()
       Sets the accept flag of the tablet event object.

       Setting the accept flag indicates that the receiver of the event wants
       the tablet event. Unwanted tablet events are sent to the parent widget.

       The accept flag is set by default.

       See also ignore().

TabletDevice QTabletEvent::device () const
       Returns the type of device that generated the event. Useful if you want
       one end of the pen to do something different than the other.

       See also TabletDevice.

const QPoint & QTabletEvent::globalPos () const
       Returns the global position of the device at the time of the event.
       This is important on asynchronous windows systems like X11; whenever
       you move your widgets around in response to mouse events, globalPos()
       can differ significantly from the current position QCursor::pos().

       See also globalX() and globalY().

int QTabletEvent::globalX () const
       Returns the global x-position of the mouse pointer at the time of the
       event.

       See also globalY() and globalPos().

int QTabletEvent::globalY () const
       Returns the global y-position of the mouse pointer at the time of the
       event.

       See also globalX() and globalPos().

void QTabletEvent::ignore ()
       Clears the accept flag parameter of the tablet event object.

       Clearing the accept flag indicates that the event receiver does not
       want the tablet event. Unwanted tablet events are sent to the parent
       widget.

       The accept flag is set by default.

       See also accept().

int QTabletEvent::isAccepted () const
       Returns TRUE if the receiver of the event handles the tablet event;
       otherwise returns FALSE.

const QPoint & QTabletEvent::pos () const
       Returns the position of the device, relative to the widget that
       received the event.

       If you move widgets around in response to mouse events, use globalPos()
       instead of this function.

       See also x(), y(), and globalPos().

int QTabletEvent::pressure () const
       Returns the pressure that is exerted on the device. This number is a
       value from 0 (no pressure) to 255 (maximum pressure). The pressure is
       always scaled to be within this range no matter how many pressure
       levels the underlying hardware supports.

QPair<;int, int> QTabletEvent::uniqueId ()
       Returns a unique ID for the current device. It is possible to generate
       a unique ID for any Wacom© device. This makes it possible to
       differentiate between multiple devices being used at the same time on
       the tablet. The first member contains a value for the type, the second
       member contains a physical ID obtained from the device. Each
       combination of these values is unique. Note: for different platforms,
       the first value is different due to different driver implementations.

int QTabletEvent::x () const
       Returns the x-position of the device, relative to the widget that
       received the event.

       See also y() and pos().

int QTabletEvent::xTilt () const
       Returns the difference from the perpendicular in the X Axis. Positive
       values are towards the tablet's physical right. The angle is in the
       range -60 to +60 degrees.

       See also yTilt().

int QTabletEvent::y () const
       Returns the y-position of the device, relative to the widget that
       received the event.

       See also x() and pos().

int QTabletEvent::yTilt () const
       Returns the difference from the perpendicular in the Y Axis. Positive
       values are towards the bottom of the tablet. The angle is within the
       range -60 to +60 degrees.

       See also xTilt().
