成员函数文档
[noexcept]
bool QBackendNode::isEnabled() const
如果后端节点已启用,则返回true
。
[noexcept]
Qt3DCore::QBackendNode::Mode QBackendNode::mode() const
返回后端模式的模式。
[noexcept]
Qt3DCore::QNodeId QBackendNode::peerId() const
返回后端节点的对等节点 ID。
[noexcept]
void QBackendNode::setEnabled(bool enabled)
通过enabled 启用或禁用后端节点。
另请参阅 isEnabled() 。
[virtual]
void QBackendNode::syncFromFrontEnd(const Qt3DCore::QNode *frontEnd, bool firstTime)
QBackendNode::syncFromFrontEndfrontEnd firstTime
当frontEnd 节点需要与后台同步其更改(通常是由于属性更改)时,方面会调用此操作。
firstTime 如果后端节点刚刚创建,则为 true
