templates / Q_OBJECT question

[marcel]

I think you can avoid templates. Why not using only a factory class + an abstract(basically for preventing instantiating this meaningless class) node class + node implementations?
The factory class will return Node(abstract) objects which you could identify later by adding a getType pure virtual method which subclasses actually implement.

For example:

AbstractNode *node = NodeFactory.CreateNode...;
switch(node->type())
{
...
case AbstractNode::eTypeANode:
  {
    dynamic_cast<TypeANode*>(node)->SomeTypeANodeSpecializedMethod();
    break;
  }
...
}

AbstractNode *node = NodeFactory.CreateNode...;
switch(node->type())
{
...
case AbstractNode::eTypeANode:
  {
    dynamic_cast<TypeANode*>(node)->SomeTypeANodeSpecializedMethod();
    break;
  }
...
}
