Property Documentation

accepted : bool

Specifies if event has been accepted

Access functions:

bool isAccepted() const
void setAccepted(bool accepted)

Notifier signal:

void acceptedChanged(bool accepted)

[read-only] button : const Qt3DRender::QPickEvent::Buttons

Specifies mouse button that caused the event

Access functions:

Qt3DRender::QPickEvent::Buttons button() const

[read-only] buttons : const int

Specifies state of the mouse buttons for the event

Access functions:

int buttons() const

[read-only] distance : const float

Specifies the distance of the hit to the camera

Access functions:

float distance() const

[read-only, since 5.14] entity : Qt3DCore::QEntity* const

The entity that the picked geometry belongs to.

If the object picker is not attached to a leaf node in the scene graph, this is useful to find which child entity was actually picked.

This property was introduced in Qt 5.14.

Access functions:

Qt3DCore::QEntity * entity() const

[read-only] localIntersection : const QVector3D

Specifies the coordinates of the hit in the local coordinate system of the picked entity

Access functions:

QVector3D localIntersection() const

[read-only] modifiers : const int

Specifies state of the mouse buttons for the event

Access functions:

int modifiers() const

[read-only] position : const QPointF

Specifies the mouse position with respect to the render area (window or quick item)

Access functions:

QPointF position() const

[read-only, since 5.14] viewport : Qt3DRender::QViewport* const

The viewport in which this event originated. A null value means the event originated from a frame graph branch without a QViewport. If a frame graph branch has a Viewport inside a Viewport the property will contain the leaf viewport.

This property was introduced in Qt 5.14.

Access functions:

Qt3DRender::QViewport * viewport() const

[read-only] worldIntersection : const QVector3D

Specifies the coordinates of the hit in world coordinate system

Access functions:

QVector3D worldIntersection() const

QPickEvent::QPickEvent()

Constructs a new QPickEvent.

[slot] void QPickEvent::setAccepted(bool accepted)

QPickEvent::setAccepted set if the event has been accepted to accepted

Note: Setter function for property accepted.

Note: Getter function for property buttons.

float QPickEvent::distance() const

QPickEvent::distance Returns distance from camera to pick point

Note: Getter function for property distance.

bool QPickEvent::isAccepted() const

QPickEvent::isAccepted Returns true if the event has been accepted

Note: Getter function for property accepted.

Note: Getter function for property localIntersection.

int QPickEvent::modifiers() const

QPickEvent::modifiers Returns bitfield to be used to check for keyboard modifiers that may be accompanying the pick event.

Note: Getter function for property modifiers.

QPointF QPickEvent::position() const

QPickEvent::position Returns mouse pointer coordinate of the pick query

Note: Getter function for property position.

QVector3D QPickEvent::worldIntersection() const
