Member Function Documentation

QBackendNode::QBackendNode(Qt3DCore::QBackendNode::Mode mode = ReadOnly)

Default-constructs an instance of QBackendNode.

[virtual] QBackendNode::~QBackendNode()

Destroys the instance of QBackendNode. The destructor is virtual.

bool QBackendNode::isEnabled() const

Returns true if the backend node is enabled.

Qt3DCore::QBackendNode::Mode QBackendNode::mode() const

Returns the mode of the backend mode.

Qt3DCore::QNodeId QBackendNode::peerId() const

Returns the peer id of the backend node.

void QBackendNode::setEnabled(bool enabled)

Enables or disables the backend node by enabled.

See also isEnabled().

[virtual] void QBackendNode::syncFromFrontEnd(const Qt3DCore::QNode *frontEnd, bool firstTime)

QBackendNode::syncFromFrontEnd frontEnd firstTime

This is called by the aspect when a frontEnd node needs to synchronize it's changes with the backend (normally due to property changes).

firstTime will be true if the backend node was just created
