GtkTreeView/GtkTreeModel design is broken since GtkTreePath is based on indexes of elements in the table. That means that for each element, you have to maintain its index: When you want to add or remove an element, you have to update all the indexes of the elements of the sibling nodes. Imagine you have a big amount of sibling nodes, performances are very bad. The behavior is more correct with ETree. Since this broken design of GtkTreePath is related to the API, I have a doubt about GTK developers will change this.

I have to customize it a little but basically, it works. -- DINH V.
