The state includes properties such as - effects, and materials; which may either be directly set on a scene node, - or inherited from its parents. - - QGLRenderState may be subclassed in advanced applications to provide a - different inheritance pattern for rendering properties - reimplement the - updateFrom() function to do this. The default implementation simply sets - an effect on the state if the argument node has an effect (found by - calling the QGLSceneNode::hasEffect() function), and sets a material on - the state if the node has a non-null material; otherwise the existing - state is left as it is. - - The render sequencer will ensure that the relevant render state is set - onto the painter at the beginning of the pass which renders all nodes - with that state. - - \sa QGLRenderOrder -*/ - -class QGLRenderStatePrivate : public QSharedData -{ -public: - QGLRenderStatePrivate(); - ~QGLRenderStatePrivate(); - QGLRenderStatePrivate *clone() const; - - QBasicAtomicInt ref; - - bool hasEffect; - QGLMaterial *material; - QGLMaterial *backMaterial; - QGL::StandardEffect standardEffect; - QGLAbstractEffect *userEffect; - const QGLSceneNode *node; -}; - -QGLRenderStatePrivate::QGLRenderStatePrivate() - : hasEffect(false) - , material(0) - , backMaterial(0) - , standardEffect(QGL::FlatColor) - , userEffect(0) - , node(0) -{ - ref = 0; -} - -QGLRenderStatePrivate::~QGLRenderStatePrivate() -{ -} - -QGLRenderStatePrivate *QGLRenderStatePrivate::clone() const -{ - QGLRenderStatePrivate *r = new QGLRenderStatePrivate; - r->hasEffect = hasEffect; - r->material = material; - r->backMaterial = backMaterial; - r->standardEffect = standardEffect; - r->userEffect = userEffect; - r->node = node; - return r; -} - -/*! - Creates a new QGLRenderState empty of any values. -*/ -QGLRenderState::QGLRenderState() - : d(0) -{ -} - -/*! - Creates a new QGLRenderState as a copy of \a other -*/ -QGLRenderState::QGLRenderState(const QGLRenderState &other) - : d(other.d) -{ - if (d) - d->ref.ref(); -} - -/*! - Destroys this QGLRenderState recovering and resources. -*/ -QGLRenderState::~QGLRenderState() -{ - if (d && !d->ref.deref()) - delete d; -} - -/*! - Assigns this QGLRenderState to be a copy of \a rhs. -*/ -QGLRenderState &QGLRenderState::operator=(const QGLRenderState &rhs) -{ - if (d != rhs.d) - { - if (d && !d->ref.deref()) - delete d; - d = rhs.d; - if (d) - d->ref.ref(); - } - return *this; -} - -/*! - Sets the values of this QGLRenderState from the \a node, where - the node has a value.
