Property Documentation
sync : bool
Holds the sync flag. When sync is true, this will force data created by a Qt3DRender::QBufferFunctor to also be updated on the frontend Qt3DRender::QBuffer node. By default sync is false.
Note: : This has no effect if the buffer's data was set directly using the data property.
Access functions:
bool | isSync() const |
void | setSync(bool sync) |
Notifier signal:
void | syncChanged(bool sync) |
type : BufferType
Holds the buffer type.
Access functions:
BufferType | type() const |
void | setType(BufferType type) |
Notifier signal:
void | typeChanged(BufferType type) |
usage : UsageType
Holds the buffer usage.
Access functions:
UsageType | usage() const |
void | setUsage(UsageType usage) |
Notifier signal:
void | usageChanged(UsageType usage) |
