[−][src]Struct qt_3d_core::QAspectEngine
Responsible for handling all the QAbstractAspect subclasses that have been registered with the scene.
C++ class: Qt3DCore::QAspectEngine
.
Responsible for handling all the QAbstractAspect subclasses that have been registered with the scene.
The Qt3D run loop is controlled by the Qt3DRender::QAspectEngine.
Qt3DCore::QAbstractAspect subclasses can be registered by calling Qt3DCore::QAspectEngine::registerAspect() which will take care of registering the aspect and in turn that will call Qt3DCore::QAbstractAspect::onRegistered();
The simulation loop is launched as soon as a root Qt3DCore::QEntity is set on the Qt3DCore::QAspectEngine. This is followed by a call to onEngineStartup() on each aspect so that they can start their simulation work.
The simulation loop is stopped when the root entity is set to Qt3DCore::QEntityPtr(). This calls onEngineShutdown() on each aspect so that they can stop performing their simulation work.
Setting a new valid root entity would restart the simulation loop again.
