// This struct will be passed to the event handler with the relevant parameters
(for example, the node you want to affect and the color to change it to)

Hi,
To respond to user events you can either inherit from osg::Callback and install

{
public:
virtual bool run(osg::Object* object, osg::Object* data) override
{
auto nv = dynam
