It is the - responsibility of the platform or generic plug-ins to register the - available touch devices via QWindowSystemInterface before generating any - touch events. Applications do not need to instantiate this class, they - should just access the global instances pointed to by QTouchEvent::device(). -*/ - -/*! \enum QTouchDevice::DeviceType - - This enum represents the type of device that generated a QTouchEvent. - - \value TouchScreen In this type of device, the touch surface and display are integrated. This - means the surface and display typically have the same size, such that there - is a direct relationship between the touch points' physical positions and the - coordinate reported by QTouchEvent::TouchPoint. As a result, Qt allows the - user to interact directly with multiple QWidgets and QGraphicsItems at the - same time. - - \value TouchPad In this type of device, the touch surface is separate from the display. There - is not a direct relationship between the physical touch location and the - on-screen coordinates. Instead, they are calculated relative to the current - mouse position, and the user must use the touch-pad to move this reference - point. Unlike touch-screens, Qt allows users to only interact with a single - QWidget or QGraphicsItem at a time. -*/ - -/*! \enum QTouchDevice::CapabilityFlag - - This enum is used with QTouchDevice::capabilities() to indicate what kind of information the - touch device or its driver can provide. - - \value Position Indicates that position information is available, meaning - that the pos() family of functions in the touch points return valid points. - - \value Area Indicates that touch area information is available, meaning that the rect() family - of functions in the touch points return valid rectangles. - - \value Pressure Indicates that pressure information is available, meaning that pressure() - returns a valid value. - - \value Velocity Indicates that velocity information is available, meaning that velocity() - returns a valid vector. - - \value RawPositions Indicates that the list returned by QTouchEvent::TouchPoint::rawScreenPositions() - may contain one or more positions for each touch point. This is relevant when - the touch input gets filtered or corrected on driver level. - - \value NormalizedPosition Indicates that the normalized position is available, meaning that normalizedPos() - returns a valid value. - - \value MouseEmulation Indicates that the device synthesizes mouse events. - This enum value has been introduced in Qt 5.5. -*/ - -/*! - Creates a new touch device instance. - By default the name is empty, the only capability is Position and type is TouchScreen. - */ -QTouchDevice::QTouchDevice() - : d(new QTouchDevicePrivate) -{ -} - -/*! - Destroys a touch device instance. - */ -QTouchDevice::~QTouchDevice() -{ - delete d; -} - -/*! - Returns the touch device type. -*/ -QTouchDevice::DeviceType QTouchDevice::type() const -{ - return d->type; -} - -/*! - Returns the touch device capabilities. - */ -QTouchDevice::Capabilities QTouchDevice::capabilities() const -{ - return d->caps; -} - -/*! - Returns the maximum number of simultaneous touch points (fingers) that - can be detected. - \since 5.2 - */ -int QTouchDevice::maximumTouchPoints() const -{ - return d->maxTouchPoints; -} - -/*! - Returns the touch device name. - - This string may often be empty.
