成员函数文档编制

bool QBackendNode:: isEnabled () const

返回 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 .

另请参阅 isEnabled ().

[虚拟] 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
