Specifies if event has been accepted
访问函数：
| bool | isAccepted () const |
| void | setAccepted (bool accepted ) |
通知程序信号：
| void | acceptedChanged (bool accepted ) |
Specifies mouse button that caused the event
访问函数：
| Qt3DRender::QPickEvent::Buttons | button () const |
Specifies state of the mouse buttons for the event
访问函数：
| int | buttons () const |
Specifies the distance of the hit to the camera
访问函数：
| float | distance () 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.
该特性在 Qt 5.14 引入。
访问函数：
| Qt3DCore::QEntity * | entity () const |
Specifies the coordinates of the hit in the local coordinate system of the picked entity
访问函数：
| QVector3D | localIntersection () const |
Specifies state of the mouse buttons for the event
访问函数：
| int | modifiers () const |
Specifies the mouse position with respect to the render area (window or quick item)
访问函数：
| QPointF | position () 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.
该特性在 Qt 5.14 引入。
访问函数：
| Qt3DRender::QViewport * | viewport () const |
Specifies the coordinates of the hit in world coordinate system
访问函数：
| QVector3D | worldIntersection () const |
