Class GTree.custom_tree_model

A base class to inherit from to make a custom tree model.

inherit model
val obj : 'obj
method connect : model_signals
method custom_row_changed : Gtk.tree_path -> 'row -> unit

Signal emitters

method custom_row_deleted : Gtk.tree_path -> unit
method custom_row_has_child_toggled : Gtk.tree_path -> 'row -> unit
method custom_row_inserted : Gtk.tree_path -> 'row -> unit
method custom_rows_reordered : Gtk.tree_path -> 'row option -> int array -> unit
method custom_unref_node : 'row -> unit

Override these to implement a cache of rows

method custom_ref_node : 'row -> unit
method custom_flags : GtkEnums.tree_model_flags list
method virtual custom_get_iter : Gtk.tree_path -> 'row option

Functions of the custom model. They must act exactly as described in the documentation of Gtk orelse Gtk may emit fatal errors.

method virtual custom_get_path : 'row -> Gtk.tree_path
method virtual custom_value : Gobject.g_type -> 'row -> column:int -> Gobject.basic

custom_value typ row ~column is the value to set in row for column column. It must must be of the type typ, i.e. the type declared for column column.
