Qt3DRender.QBuffer ¶

概要 ¶

详细描述 ¶

Data can either be provided directly using setData() or by specifying a generator with setDataGenerator() and providing a QBufferDataGeneratorPtr .

When using a generator the data will be loaded asynchronously in a job. The loaded data can be read back if the syncData flag is set to true.
