## Description

The GdaTreeMgrColumns is a GdaTreeManager object which creates a node for each column in a table.

It uses the GdaMetaStore associated to a GdaConnection to get the columns list for a table designated by its name and the database schema it is in; it's up to the caller to make sure the data in the GdaMetaStore is up to date.

The GdaConnection to be used needs to be specified when the object is created. The table name and schema can however be specified when the object is created, and if not, are fetched from the GdaTreeNode below which the nodes will be placed (using `gda_tree_node_fetch_attribute()`).

## Functions

### gda_tree_mgr_columns_new ()

    GdaTreeManager *
    gda_tree_mgr_columns_new (GdaConnection *cnc,
                              const gchar *schema,
                              const gchar *table_name);

Creates a new GdaTreeManager object which will add one tree node for each column in the table named `table_name` in the `schema` schema.

#### Parameters

cnc | a GdaConnection object |
schema | a schema name |
table_name | the name of the table |

#### Returns

a new GdaTreeManager object.
