Detailed Description

Member Type Documentation

enum QSceneChange::DeliveryFlagflags QSceneChange::DeliveryFlags

The types of change that can be sent and received by Qt3D's change notification system.

Constant Value
Qt3DCore::QSceneChange::BackendNodes 0x0001
Qt3DCore::QSceneChange::Nodes 0x0010
Qt3DCore::QSceneChange::DeliverToAll BackendNodes | Nodes

The DeliveryFlags type is a typedef for QFlags<DeliveryFlag>. It stores an OR combination of DeliveryFlag values.

Qt3DCore::QSceneChange::DeliveryFlags QSceneChange::deliveryFlags() const

Returns the set delivery flags.

See also setDeliveryFlags().

void QSceneChange::setDeliveryFlags(Qt3DCore::QSceneChange::DeliveryFlags flags)

Sets the delivery flags of the change to flags.
