详细描述
The QPickEvent class holds information when an object is picked
This is received as a parameter in most of the QObjectPicker component signals when picking succeeds.
参见 QPickingSettings, QPickTriangleEvent, and QObjectPicker.

成员函数
QPickEvent::QPickEvent()
Constructs a new QPickEvent.
QPickEvent::QPickEvent(const QPointF &position, const QVector3D &intersection, const QVector3D &localIntersection, float distance)
Constructs a new QPickEvent with the given parameters: position, intersection, localIntersection and distance
QPickEvent::QPickEvent(const QPointF &position, const QVector3D &worldIntersection, const QVector3D &localIntersection, float distance, Buttons button, int buttons, int modifiers)
Constructs a new QPickEvent with the given parameters: position, worldIntersection, localIntersection, distance, button, buttons and modifiers
Buttons QPickEvent::button() const
QPickEvent::button Returns mouse button that caused the event
Note: Getter function for property button.
int QPickEvent::buttons() const
QPickEvent::buttons Returns bitfield to be used to check for mouse buttons that may be accompanying the pick event.
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.
QVector3D QPickEvent::localIntersection() const
QPickEvent::localIntersection Returns coordinates of the hit in the local coordinate system of the picked entity
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.
[slot] void QPickEvent::setAccepted(bool accepted)
QPickEvent::setAccepted set if the event has been accepted to accepted
Note: Setter function for property accepted.
参见 isAccepted().
QVector3D QPickEvent::worldIntersection() const
QPickEvent::worldIntersection Returns coordinates of the hit in world coordinate system
Note: Getter function for property worldIntersection.
