Detailed Description#

Data can be provided directly using setData() .

class PySide6.Qt3DCore.Qt3DCore.QBuffer([parent=None])#

Parameters:: parent – PySide6.Qt3DCore.Qt3DCore.QNode

Constructs a new QBuffer with parent.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property PᅟySide6.Qt3DCore.Qt3DCore.QBuffer.accessType: AccessType#

Returns the AccessType of the buffer.
