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) |
button : const Qt3DRender::QPickEvent::Buttons
Specifies mouse button that caused the event
Access functions:
| Qt3DRender::QPickEvent::Buttons | button() const |
buttons : const int
Specifies state of the mouse buttons for the event
Access functions:
| int | buttons() const |
distance : const float
Specifies the distance of the hit to the camera
Access functions:
| float | distance() const |
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 |
localIntersection : const QVector3D
Specifies the coordinates of the hit in the local coordinate system of the picked entity
Access functions:
| QVector3D | localIntersection() const |
modifiers : const int
Specifies state of the mouse buttons for the event
Access functions:
| int | modifiers() const |
position : const QPointF
Specifies the mouse position with respect to the render area (window or quick item)
Access functions:
| QPointF | position() const |
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 |
worldIntersection : const QVector3D
Specifies the coordinates of the hit in world coordinate system
Access functions:
| QVector3D | worldIntersection() const |
