typedef sigc::slot< void, const Gtk::TreeModel::iterator&, Glib::ValueBase&, int > | SlotModify |
For instance, void on_modify(const Gtk::TreeModel::iterator& iter, Glib::ValueBase& value, int column);. | |

|
For instance, void on_modify(const Gtk::TreeModel::iterator& iter, Glib::ValueBase& value, int column);. where iter is an iterator to a row in the child model, value is an output parameter in which you must store the value to be used in the parent model's row, column is the column in the parent row whose row value you must provide in the value output paramater. |
|
For instance, bool on_visible(const TreeModel::const_iterator& iter); This should return true if the given row should be visible and false otherwise.

This function should almost never be called. It clears the filter of any cached iterators that haven't been reffed with ref_node(). This might be useful if the child model being filtered is static (and doesn't change often) and there has been a lot of unreffed access to nodes. As a side effect of this function, all unreffed itters will be invalid.

Converts child_path to a path relative to filter .
That is, child_path points to a path in the child model. The rerturned path will point to the same row in the filtered model. If child_path isn't a valid path on the child model, then
