示例1: setRelatedModelObject
bool Relationship::setRelatedModelObject(boost::optional<ModelObject> relatedModelObject)
{
assertSingular(true);
bool result = false;
if (isSettable()) {
// handle ComponentData set
if (relatedModelObject && relatedModelObject->optionalCast<ComponentData>()) {
if (relatedModelObject->model() != m_object.model()) {
if (relatedModelObject->model().optionalCast<Component>()) {
return setRelatedModelObject(relatedModelObject->model().cast<Component>());
}
}
}
QVariant value = QVariant::fromValue(relatedModelObject);
m_object.getImpl<detail::ModelObject_Impl>()->setProperty(m_name.c_str(), value);
// check set
boost::optional<ModelObject> newValue = this->relatedModelObject();
if (relatedModelObject){
if (newValue){
result = (relatedModelObject->handle() == newValue->handle());
}
}else{
result = !newValue;
