:

Can we have a function to return the index of a
treeitem on a tree please?

public int Treeitem.getIndexOnTheTree(){
//return the index of the treeitem on the tree
}

Also, I would like to have:

public Treeitem Tree.getTreeitem(int index){
//return the treeitem specified by the index among all
the items of the tree
}
