= class Gtk::TreeModelSort
== super class
* GLib::Object
== included modules
* Gtk::TreeSortable
* Gtk::TreeModel
== class methods
--- Gtk::TreeModelSort.new(child_model)
Creates a new Gtk::TreeModel, with child_model as the child_model.
* child_model: A Gtk::TreeModel
* Returns: A new Gtk::TreeModel.
== public instance methods
--- model
Returns the model the Gtk::TreeModelSort is sorting.
* Returns: the "child model" being sorted
--- model=(child_model)
Sets the model of the Gtk::TreeModelSort to be child_model. If child_model is nil, then the old model is unset. The sort method is unset as a result of this call. This method is for construct time only.
The model will be in an unsorted state until a sort method is set.
* child_model: A Gtk::TreeModel, or nil.
* Returns: model
--- set_model(child_model)
Same as model=.
* child_model: A Gtk::TreeModel, or nil.
* Returns: self
--- convert_child_path_to_path(child_path)
Converts child_path to a path relative to the Gtk::TreeModelSort. That is, child_path points to a path in the child model. The returned path will point to the same row in the sorted model. If child_path isn't a valid path on the child model, then nil is returned.
* child_path: A Gtk::TreePath to convert
* Returns: A newly allocated Gtk::TreePath, or nil
--- convert_child_iter_to_iter(child_iter)
Gets a Gtk::TreeIter which point to the row in the Gtk::TreeModelSort that corresponds to the row pointed at by child_iter.
* child_iter: A valid Gtk::TreeIter pointing to a row on the child model
* Returns: A Gtk::TreeIter.
--- convert_path_to_child_path(sorted_path)
Converts sorted_path to a path on the child model of the Gtk::TreeModelSort. That is, sorted_path points to a location in the Gtk::TreeModelSort. The returned path will point to the same location in the model not being sorted. If sorted_path does not point to a location in the child model, nil is returned.
* sorted_path: A Gtk::TreePath to convert
* Returns: A newly allocated Gtk::TreePath, or nil
--- convert_iter_to_child_iter(sorted_iter)
Gets a Gtk::TreeIter which point to the row pointed to by sorted_iter.
* sorted_iter: A valid Gtk::TreeIter pointing to a row on the Gtk::TreeModelSort.
* Returns: A Gtk::TreeIter
--- reset_default_sort_func
This resets the default sort function to be in the 'unsorted' state. That is, it is in the same order as the child model. It will re-sort the model to be in the same order as the child model only if the Gtk::TreeModelSort is in 'unsorted' state.
* Returns: self
--- clear_cache
This method should almost never be called. It clears the Gtk::TreeModelSort of any cached iterators that haven't been reffed by GTK+. This might be useful if the child model being sorted is static (and doesn't change often) and there has been a lot of unreffed access to nodes. As a side effect of this method, all unreffed iters will be invalid.
* Returns: self
