The new model is mostly API-compatible with the old model (minimal changes were required), but is a lot faster and has a lot of very desirable features. - the model does no longer support a tree, just a list of files in a given directory - the storage has been moved to a GArray as opposed to a tree - no more dependency on GtkFileSystem - columns are managed by the creator of the model, so any number of nodes can be added as needed. This also makes the API more similar to GtkListStore. - Values are filled on demand using a function given when creating the model. - The function can decide to let the model cache returned values or decide to be called again the next time the value is queried. - implements GtkTreeSortable - _gtk_file_system_model_get_value() was added to significantly speed up value access, which is necessary when sorting large models.
