Detailed Description¶
The Qt3D run loop is controlled by the Qt3DRender::QAspectEngine.
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
QEntity
is set on theQAspectEngine
. 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.

(command)¶ - Parameters
command – unicode
- Return type
object
Executes the given
command
on aspect engine. Valid commands are:“list aspects”
Returns the reply for the command.
