◆ setEllipseDiameters()

void QQuickTouchPoint::setEllipseDiameters ( const QSizeF & d)

\qmlproperty size QtQuick::TouchPoint::ellipseDiameters

This property holds the major and minor axes of the ellipse representing the covered area of the touch point.

void QQuickTouchPoint::setInUse ( bool inUse)
inline

◆ setPointId()

QT_BEGIN_NAMESPACE void QQuickTouchPoint::setPointId ( int id)

\qmltype TouchPoint \nativetype QQuickTouchPoint \inqmlmodule QtQuick

Describes a touch point in a MultiPointTouchArea.

The TouchPoint type contains information about a touch point, such as the current position, pressure, and area.

\qmlproperty int QtQuick::TouchPoint::pointId

This property holds the point id of the touch point.

Each touch point within a MultiPointTouchArea will have a unique id.

Definition at line 42 of file qquickmultipointtoucharea.cpp.

◆ setPosition()

void QQuickTouchPoint::setPosition ( QPointF p)

\qmlproperty real QtQuick::TouchPoint::x \qmlproperty real QtQuick::TouchPoint::y

These properties hold the current position of the touch point.

Definition at line 57 of file qquickmultipointtoucharea.cpp.

◆ setPressed()

void QQuickTouchPoint::setPressed ( bool pressed)

\qmlproperty bool QtQuick::TouchPoint::pressed

This property holds whether the touch point is currently pressed.

Definition at line 159 of file qquickmultipointtoucharea.cpp.

◆ setPressure()

void QQuickTouchPoint::setPressure ( qreal pressure)

\qmlproperty real QtQuick::TouchPoint::pressure \qmlproperty vector2d QtQuick::TouchPoint::velocity

These properties hold additional information about the current state of the touch point.

\list

  • pressure is a value in the range of 0.0 to 1.0.
  • velocity is a vector with magnitude reported in pixels per second. \endlist

Not all touch devices support velocity. If velocity is not supported, it will be reported as 0,0.

Definition at line 100 of file qquickmultipointtoucharea.cpp.

◆ setPreviousX()

void QQuickTouchPoint::setPreviousX ( qreal previousX)

\qmlproperty real QtQuick::TouchPoint::previousX \qmlproperty real QtQuick::TouchPoint::previousY

These properties hold the previous position of the touch point.

Definition at line 196 of file qquickmultipointtoucharea.cpp.

◆ setPreviousY()

void QQuickTouchPoint::setPreviousY ( qreal previousY)

Definition at line 204 of file qquickmultipointtoucharea.cpp.

◆ setRotation()

void QQuickTouchPoint::setRotation ( qreal r)

\qmlproperty real QtQuick::TouchPoint::rotation

Since
5.9

This property holds the angular orientation of this touch point. The return value is in degrees, where zero (the default) indicates the finger or token is pointing upwards, a negative angle means it's rotated to the left, and a positive angle means it's rotated to the right. Most touchscreens do not detect rotation, so zero is the most common value.

◆ setSceneX()

void QQuickTouchPoint::setSceneX ( qreal sceneX)

\qmlproperty real QtQuick::TouchPoint::sceneX \qmlproperty real QtQuick::TouchPoint::sceneY

These properties hold the current position of the touch point in scene coordinates.

Definition at line 219 of file qquickmultipointtoucharea.cpp.

◆ setSceneY()

void QQuickTouchPoint::setSceneY ( qreal sceneY)

Definition at line 227 of file qquickmultipointtoucharea.cpp.

◆ setStartX()

void QQuickTouchPoint::setStartX ( qreal startX)

\qmlproperty real QtQuick::TouchPoint::startX \qmlproperty real QtQuick::TouchPoint::startY

These properties hold the starting position of the touch point.

Definition at line 174 of file qquickmultipointtoucharea.cpp.

◆ setStartY()

void QQuickTouchPoint::setStartY ( qreal startY)

Definition at line 182 of file qquickmultipointtoucharea.cpp.

◆ setUniqueId()

void QQuickTouchPoint::setUniqueId ( const QPointingDeviceUniqueId & id)

\qmlproperty pointingDeviceUniqueId QtQuick::TouchPoint::uniqueId

Since
5.9

This property holds the unique ID of the touch point or token.

It is normally empty, because touchscreens cannot uniquely identify fingers. But when it is set, it is expected to uniquely identify a specific token (fiducial object).

Interpreting the contents of this ID requires knowledge of the hardware and drivers in use (e.g. various TUIO-based touch surfaces).
