Detailed Description#

While QFrameGraphNodes can be individually enabled and disabled via the enabled property, this can become tedious when an entire path needs to be turned on or off. QSubtreeEnabler is a convenience node that makes this use case trivial, allowing all of its children to be controlled by a single switch.

QSubtreeEnabler is enabled by default.

class Enablement#

Specifies whether subtree enablement is persistent or transient.

Constant

Description

Qt3DRender.QSubtreeEnabler.Persistent

The value of enabled is persistent. This is the default.

Qt3DRender.QSubtreeEnabler.SingleShot

The value of enabled will last for a single frame and then be reset to false. This might be used for a subtree drawing to an FBO, for example, to only update the FBO when the relevant portions of the scene changed.
