## Description

ClutterModel is a generic list model API which can be used to implement the model-view-controller architectural pattern in Clutter.

The ClutterModel class is a list model which can accept most GObject types as a column type.

#### Creating a simple ClutterModel

The example below shows how to create a simple list model.

    };

    {
      ClutterModel *model;
      gint i;

      model = clutter_list_model_new (N_COLUMNS,
                                      // column type, title
                                      G_TYPE_INT,     "my integers",
                                      G_TYPE_STRING,  "my strings");
      for (i = 0; i < 10; i++)
        {
          gchar *string = g_strdup_printf ("String %d", i);
          clutter_model_append (model,
                                COLUMN_INT, i,
                                COLUMN_STRING, string,
                                -1);
          g_free (string);
        }

    }

#### Iterating through a ClutterModel

Iterating through the model consists of retrieving a new ClutterModelIter pointing to the starting row, and calling `clutter_model_iter_next()` or `clutter_model_iter_prev()` to move forward or backwards, repectively.

A valid ClutterModelIter represents the position between two rows in the model. For example, the "first" iterator represents the gap immediately before the first row, and the "last" iterator represents the gap immediately after the last row. In an empty sequence, the first and last iterators are the same.

      // fill the model
      model = populate_model ();

      // get the iterator for the first row in the model
      iter = clutter_model_get_first_iter (model);
      while (!clutter_model_iter_is_last (iter))
        {
          print_row (iter);

          iter = clutter_model_iter_next (iter);
        }

      // Make sure to unref the iter
      g_object_unref (iter);
    }

ClutterModel is an abstract class. Clutter provides a list model implementation called ClutterListModel which has been optimised for insertion and look up in sorted lists.

ClutterModel is available since Clutter 0.6

#### ClutterModel custom properties for ClutterScript

ClutterModel defines a custom property "columns" for ClutterScript which allows defining the column names and types. It also defines a custom "rows" property which allows filling the ClutterModel with some data.

The definition below will create a ClutterListModel with three columns: the first one with name "Name" and containing strings; the second one with name "Score" and containing integers; the third one with name "Icon" and containing ClutterTextures. The model is filled with three rows. A row can be defined either with an array that holds all columns of a row, or an object that holds "column-name" : "column-value" pairs.
