Contains position information for an object in a 3D scene. The object is considered to be a single point in the coordinate space without dimensions.
This property holds the parent scene as a read only value.
If the object has no parent scene, the value is 0.
访问函数:
Q3DScene * | parentScene () |
This property holds the 3D position of the object.
注意: Currently setting this property has no effect for Q3DCamera , as the position is handled internally.
访问函数:
QVector3D | 位置 () const |
void | setPosition (const QVector3D & position ) |
通知程序信号:
void | positionChanged (const QVector3D & position ) |
Constructs a new 3D object with the position set to origin by default. An optional parent parameter can be given and is then passed to the QObject 构造函数。
