A bit of context:
Qt 5.15, since by default qquicklayout is an internal qt type but we need
to have a custom intermediary attached Layout type, I am using code like
this:
auto metaObject =
QMetaType::metaObjectForType(QMetaType::type("QQuickLayout*"));
const auto func = qmlAttachedPropertiesFunction(parent, metaObject);
m_attachedProperties.object = qmlAttachedPropertiesObject(parent, func,
true);
// below are registrations of custom bindings
this works fine in our actual application but for whatever reason when qml
tests are being run the line
QMetaType::metaObjectForType(QMetaType::type("QQuickLayout*"));
returns nullptr in the constructor of a type that has a custom attached
layout. it also returns nullptr in qmlEngineAvailable of the test's setup
class. I am assuming the registration of qquicklayout is deferred somewhere
but what are the exact timings and conditions?
