Detailed Description
The QWSMouseHandler class is a mouse driver/handler for Qt/Embedded.
The mouse driver/handler handles events from system devices and
generates mouse events.
A QWSMouseHandler will usually open some system device in its
constructor, create a QSocketNotifier on that opened device and when
it receives data, it will call mouseChanged() to send the event
to Qt/Embedded for relaying to clients.
See also Qt/Embedded.
Member Function Documentation
QWSMouseHandler::QWSMouseHandler ( const QString & driver = QString::null, const QString & device = QString::null )
Constructs a mouse handler. This becomes the primary mouse
handler.
Note that once created, mouse handlers are controlled by the
system and should not be deleted.
The driver and device arguments are not used by this base
class.
QWSMouseHandler::~QWSMouseHandler () [virtual]
Destroys the mouse handler. You should not call this directly.
void QWSMouseHandler::calibrate ( QWSPointerCalibrationData * ) [virtual]
This method is reimplemented in the calibrated mouse handler
to set calibration information (from, for instance, the QPE
calibration screen). This version does nothing.
void QWSMouseHandler::clearCalibration () [virtual]
This method is reimplemented in the calibrated mouse handler
to clear calibration information. This version does nothing.
void QWSMouseHandler::limitToScreen ( QPoint & pt )
Ensures that the given point, pt is within the screen's
boundaries, changing pt if necessary.
void QWSMouseHandler::mouseChanged ( const QPoint & pos, int bstate )
When a mouse event occurs this function is called with the mouse's
position in pos, and the state of its buttons in bstate.
const QPoint & QWSMouseHandler::pos () const
Returns the mouse position.
