The - QGLPickNode instance receives events sent to it by picking views, such - as the QGLView class, and emits relevant signals in response. - - QGLSceneObjects wanting to support picking, should implement the methods - \list - \o QGLSceneNode::pickNode() - \o QGLSceneNode::setPickNode() - \endlist - and also implement rendering such that the QGLPainter has the relevant - \l{QGLPainter::setObjectPickId()}{pick id function} called. - - These functions are already implemented for the QGLSceneNode object type. - - Picking can then be simply enabled by calling the QGLAbstractScene function - setPickable() to turn on picking and generate pick nodes for the relevant - scene objects. - - In order to respond to picking, the view class should simply register the - picknodes, and connect a relevant slot to the pick nodes signal. - - For the QGLView class that code is simply: - \code - QList<QGLPickNode *>nodes = manager->pickNodes(); - foreach (QGLPickNode *node, nodes) - { - registerObject(node->id(), node); - connect(node, SIGNAL(clicked()), - this, SLOT(objectPicked())); - } - \endcode - - The pick nodes should be unregistered with similar code for the QGLView if - switching to a different scene. - - To be able to recover the relevant QGLSceneNode inside the called slot, - the object may be set onto the QGLPickNode with the setTarget() function, - and recovered with target() inside the slot, since the QGLPickNode will - be the sender() for the slot. - - QGLSceneNode already sets itself as the target during the pick enable step. - - \sa QGLSceneNode, QGLView -*/ - -/*! - Construct a new QGLPickNode object managed by and parented onto - the \a parent scene.
