Q: Qt - [c++] replacing material on a QEntity

[kevin_d]

Hello Forum!

How can i remove a QMaterial* component from a QEntity the safe way?
given the sequence:

// create the objects (of course with suitable arguments)
auto* entity = new Qt3DCore::QEntity(_root);
auto* mesh = new Qt3DExtras::QCuboidMesh;
auto* scaleTransform = new Qt3DCore::QTransform;
auto* material = new Qt3DExtras::QPhongMaterial;
auto* anotherScaleTransform = new Qt3DCore::QTransform;

// assign unordered
entity->addComponent(mesh),
entity->addComponent(scaleTransform);
entity->addComponent(material);
entity->addComponent(anotherScaleTransform);

// what i want:
entity->removeComponent(material);
entity->addComponent(anotherMaterial);

best regards, kevin
