selection.paths( toCollapse );
if( !toCollapse.size() )
{
return;
}
GafferScene::PathMatcherData *expandedData = expandedPaths();
PathMatcher &expanded = expandedData->writable();
for( vector<string>::const_iterator it = toCollapse.begin(), eIt = toCollapse.end(); it != eIt; ++it )
{
/// \todo It would be nice to be able to get ScenePaths out of
/// PathMatcher::paths() directly.
ScenePlug::ScenePath path;
ScenePlug::stringToPath( *it, path );
if( !expanded.removePath( path ) )
{
if( path.size() <= 1 )
{
continue;
}
selection.removePath( path );
path.pop_back(); // now the parent path
expanded.removePath( path );
selection.addPath( path );
