示例1: plugInputChanged
void BoxIO::plugInputChanged( Plug *plug )
{
// An input has changed either on this node or on
// the parent box node. This gives us the opportunity
// to discover our promoted plug and connect to its
// signals.
Plug *promoted = nullptr;
if( m_direction == Plug::In && plug == inPlugInternal() )
{
promoted = promotedPlug();
}
else if( m_direction == Plug::Out && plug == promotedPlug() )
{
promoted = plug;
}
if( promoted )
{
m_promotedPlugNameChangedConnection = promoted->nameChangedSignal().connect(
boost::bind( &BoxIO::promotedPlugNameChanged, this, ::_1 )
);
m_promotedPlugParentChangedConnection = promoted->parentChangedSignal().connect(
boost::bind( &BoxIO::promotedPlugParentChanged, this, ::_1 )

}
// Detect manual setups created by legacy scripts from before
// we added the pass-through, and fix them to include a pass-through.

!passThroughPlugInternal()

}
// If a connection has been made to our passThrough plug
// for the first time, then we also want to create an enabled
// plug for the Box and connect to it.
