your code looks ok to me. I replaced NamedNodeFinder::check in the
10loading.cpp tutorial with the following (based on your code):
Action::ResultE check(NodePtr& node)
{
if(node->getCore()->getType().isDerivedFrom(MaterialGroup::getClassType()))
{
MaterialGroupPtr mg = MaterialGroupPtr::dcast(node->getCore());
ChunkMaterialPtr material =
ChunkMaterialPtr::dcast(mg->getMaterial());
MFStateChunkPtr* chunks = material->getMFChunks();
TextureChunkPtr texture_chunk = NullFC;
for ( MFStateChunkPtr::const_iterator i = chunks->begin();
i != chunks->end(); i++ )
{
if ((*i)->getType() == TextureChunk::getClassType())
{
texture_chunk = TextureChunkPtr::dcast(*i);
}
}
if (texture_chunk != NullFC)
{
std::cout << "create textureChunk" << std::endl;
}
}
return Action::Continue;
}
and it seems to work fine.
And to answer your other question: No, you don't have to do the
begin/endEdit if you're only reading, you only need that for changes.
Hope it helps
Dirk
