QQuick3DNode::QQuick3DNode ( QQuick3DNode * parent = nullptr )

explicit

\qmltype Node \inherits Object3D \inqmlmodule QtQuick3D

The base component for an object that exists in a 3D scene.

The Node type serves as the base class for other spatial types, such as, \l Model, \l Camera, \l Light. These objects represent an entity that exists in the 3D scene, due to having a position and other properties in the 3D world. With the exception of the root node(s), all Node types are transformed relative to their parent Node, that is, in local coordinates. In many ways the Node type serves the same purpose in Qt Quick 3D scenes as \l Item does for Qt Quick scenes.

In addition to types deriving from Node, it is also possible to parent other types to a Node. This includes QObject instances, where the Node merely serves as the \l{QObject::parent()}{QObject parent}, and \l{Qt Quick 3D Scenes with 2D Content}{Qt Quick items}.

Wrapping other objects for the purpose of grouping them into components or sub-trees can be a convenient way to, for example, animated a group of nodes as a whole. This snippet shows how to use Node to animate a camera:

\qml Node { PerspectiveCamera { position: Qt.vector3d(0, 0, -600) }

SequentialAnimation on eulerRotation.y { loops: Animation.Infinite PropertyAnimation { duration: 5000 from: 0 to: 360 } } } \endqml

Node has to be used also if creating a scene outside of \l View3D, for example for the purpose of switching scenes on the fly, or showing the same scene on multiple views.

\qml Node { id: standAloneScene

DirectionalLight {}

Model { source: "#Sphere" materials: [ DefaultMaterial {} ] }

PerspectiveCamera { z: 600 } }

View3D { importScene: standAloneScene } \endqml

Invoked after the root component that caused this instantiation has completed construction.

Here is the caller graph for this function:

◆ connectNotify()

void QQuick3DNode::connectNotify ( const QMetaMethod & signal )

overrideprotectedvirtual

Since: 5.0

This virtual function is called when something has been connected to signal in this object.

If you want to compare signal with a specific signal, you can use QMetaMethod::fromSignal() as follows:

if (signal == QMetaMethod::fromSignal(&MyObject::valueChanged)) {
    // signal is valueChanged
}

Warning: This function violates the object-oriented principle of modularity. However, it might be useful when you need to perform expensive initialization only if something is connected to a signal.; This function is called from the thread which performs the connection, which may be a different thread from the thread in which this object lives. This function may also be called with a QObject internal mutex locked. It is therefore not allowed to re-enter any QObject functions, including isSignalConnected(), from your reimplementation. If you lock a mutex in your reimplementation, make sure that you don't call QObject functions with that mutex held in other places or it will result in a deadlock.

See also: connect(), disconnectNotify()

Reimplemented from QObject.

Definition at line 500 of file qquick3dnode.cpp.

References d, and signal.

◆ disconnectNotify()

void QQuick3DNode::disconnectNotify ( const QMetaMethod & signal )

overrideprotectedvirtual

Since: 5.0

This virtual function is called when something has been disconnected from signal in this object.

See connectNotify() for an example of how to compare signal with a specific signal.

If all signals were disconnected from this object (e.g., the signal argument to disconnect() was \nullptr), disconnectNotify() is only called once, and the signal will be an invalid QMetaMethod (QMetaMethod::isValid() returns false).

Warning: This function violates the object-oriented principle of modularity. However, it might be useful for optimizing access to expensive resources.; This function is called from the thread which performs the disconnection, which may be a different thread from the thread in which this object lives. This function may also be called with a QObject internal mutex locked. It is therefore not allowed to re-enter any QObject functions, including isSignalConnected(), from your reimplementation. If you lock a mutex in your reimplementation, make sure that you don't call QObject functions with that mutex held in other places or it will result in a deadlock.
