29 * Note that there are some cases when using QPersistentModelIndexes from this model will not give
30 * expected results. QPersistentIndexes will remain valid and updated if its siblings are added or
31 * removed. However, if the QPersistentIndex or one of its ancestors is moved, the QPersistentIndex will become
32 * invalid. For example, if a file or directory is renamed after storing a QPersistentModelIndex for it,
33 * the index (along with any stored children) will become invalid even though it is still in the model. The reason
34 * for this is that moves of files and directories are treated as separate insert and remove actions.
73 * Apart from the support for the ShowRoot flag, this is equivalent to dirLister()->openUrl(url, flags)
75 * Unless ShowRoot is set, the item for this directory will NOT be shown, the model starts at its children.
82 * Set the directory lister to use by this model, instead of the default KDirLister created internally.
108 * @short Lists subdirectories using fetchMore() as needed until the given @p url exists in the model.
112 * However if you want the tree to show a given URL (i.e. open the tree recursively until that URL),
126 * Note that for most things (renaming, changing size etc.), KDirLister's signals tell the model already.
