Hi Robert, I've seen this problem in this situation :
- a class derived from osg::Group who override the "childInserted" - in the "childInserted" : get the newly inserted child using "getChild" But, to ensure that new childs are always inserted at the end of the group (which is what I needs in this particular situtation), I insert them using : pGroup->insertChild(pNewChild, -1) So the child is always added at the end, but the index passed in "childInserted" method was invalid. > passing a index more than one beyond the end of current children size > suggests that something is amiss Not sure about that, when I manage vector or list of objects, I always apply the following rule in the "insert" metod (and that's usefull !) - if index < size => insert as usual - if index > size => insert at the end and, if index is "int" and not "unsigned int" : - if index < 0 => insert at the end So : - to prepend : insert(0, something) - to append : insert(-1, something) - to insert : insert(index, something) But usually, when I do that, the "insert" method returns the "real inserted index" : - return value < 0 => invalid/error/some problem - return value = index => object was inserted where asked to - return value != index => object was inserted at the end Cheers, Aurelien ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=53041#53041 _______________________________________________ osg-submissions mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-submissions-openscenegraph.org
