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 <a href="#x">x</a>(), <a href="#y">y</a>(), <a href="#pos">pos</a>(), <a href="#globalX">globalX</a>(), <a href="#globalY">globalY</a>() and <a href="#globalPos">globalPos</a>(). 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 <a href="#pressure">pressure</a>(), the <a href="#xTilt">xTilt</a>() and <a href="#yTilt">yTilt</a>(), as well as the +type of device being used with <a href="#device">device</a>() (see <a href="#TabletDevice-enum">TabletDevice</a>). +<p> A tablet event contains a special accept flag that indicates +whether the receiver wants the event. You should call +<a href="#accept">QTabletEvent::accept</a>() if you handle the tablet event; otherwise +it will be sent to the parent widget. +<p> The <a href="qwidget.html#setEnabled">QWidget::setEnabled</a>() function can be used to enable or +disable mouse and keyboard events for a widget. +<p> The event handler <a href="qwidget.html#tabletEvent">QWidget::tabletEvent</a>() 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. +<p> <p>See also <a href="events.html">Event Classes</a>. + +<hr><h2>Member Type Documentation</h2> +<h3 class=fn><a name="TabletDevice-enum"></a>QTabletEvent::TabletDevice</h3> + +<p> This enum defines what type of device is generating the event. +<ul> +<li><tt>QTabletEvent::NoDevice</tt> - No device, or an unknown device. +<li><tt>QTabletEvent::Puck</tt> - A Puck (a device that is similar to a flat mouse with +a transparent circle with cross-hairs). +<li><tt>QTabletEvent::Stylus</tt> - A Stylus (the narrow end of the pen). +<li><tt>QTabletEvent::Eraser</tt> - An Eraser (the broad end of the pen). +</ul> +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="QTabletEvent"></a>QTabletEvent::QTabletEvent ( <a href="qevent.html#Type-enum">Type</a> t, const <a href="qpoint.html">QPoint</a> & pos, const <a href="qpoint.html">QPoint</a> & globalPos, int device, int pressure, int xTilt, int yTilt, const <a href="qpair.html">QPair</a><int, int> & uId ) +</h3> + +Construct a tablet event of type <em>t</em>.
