This class was introduced in QtDataVisualization 1.0.
Properties
- parentScene : Q3DScene* const
- position : QVector3D
Public Functions
| Q3DObject(QObject *parent = nullptr) | |
| virtual | ~Q3DObject() |
| virtual void | copyValuesFrom(const Q3DObject &source) |
| Q3DScene * | parentScene() |
| QVector3D | position() const |
| void | setPosition(const QVector3D &position) |
Signals
| void | positionChanged(const QVector3D &position) |
Protected Functions
Detailed Description
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.
Property Documentation
parentScene : Q3DScene* const
This property holds the parent scene as a read only value.
If the object has no parent scene, the value is 0.
Access functions:
| Q3DScene * | parentScene() |
position : QVector3D
This property holds the 3D position of the object.
Note: Currently setting this property has no effect for Q3DCamera, as the position is handled internally.
Access functions:
| QVector3D | position() const |
| void | setPosition(const QVector3D &position) |
Notifier signal:
| void | positionChanged(const QVector3D &position) |
Member Function Documentation
Q3DObject::Q3DObject(QObject *parent = nullptr)
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 constructor.
[virtual] Q3DObject::~Q3DObject()
Destroys the 3D object.
[virtual] void Q3DObject::copyValuesFrom(const Q3DObject &source)
Copies the 3D object position from the given source 3D object to this 3D object instance.
[protected] bool Q3DObject::isDirty() const
Returns whether the 3D object has changed.
[protected] void Q3DObject::setDirty(bool dirty)
Sets dirty to true if the 3D object has changed since the last update.
