## Description

You may wish to begin by reading the text widget conceptual overview which gives an overview of all the objects and data types related to the text widget and how they work together.

## Details

### GtkTextTagTable

    typedef struct _GtkTextTagTable GtkTextTagTable;

### GtkTextTagTableForeach ()

    void                (*GtkTextTagTableForeach)           (GtkTextTag *tag,
                                                             gpointer data);

`tag` : |
`data` : |

### gtk_text_tag_table_new ()

    GtkTextTagTable *   gtk_text_tag_table_new              (void);

Creates a new GtkTextTagTable. The table contains no tags by default.

Returns : | a new GtkTextTagTable

### gtk_text_tag_table_add ()

    void                gtk_text_tag_table_add              (GtkTextTagTable *table,
                                                             GtkTextTag *tag);

Add a tag to the table. The tag is assigned the highest priority in the table.

`tag` must not be in a tag table already, and may not have the same name as an already-added tag.

`table` : | a GtkTextTagTable
`tag` : | a GtkTextTag

### gtk_text_tag_table_remove ()

    void                gtk_text_tag_table_remove           (GtkTextTagTable *table,
                                                             GtkTextTag *tag);

Remove a tag from the table. This will remove the table's reference to the tag, so be careful - the tag will end up destroyed if you don't have a reference to it.

`table` : | a GtkTextTagTable
`tag` : | a GtkTextTag

### gtk_text_tag_table_lookup ()

    GtkTextTag *        gtk_text_tag_table_lookup           (GtkTextTagTable *table,
                                                             const gchar *name);

Look up a named tag.

`table` : | a GtkTextTagTable
`name` : | name of a tag
Returns : | The tag, or `NULL` if none by that name is in the table.

### gtk_text_tag_table_foreach ()

    void                gtk_text_tag_table_foreach          (GtkTextTagTable *table,
                                                             GtkTextTagTableForeach func,
                                                             gpointer data);

Calls `func` on each tag in `table`, with user data `data`. Note that the table may not be modified while iterating over it (you can't add/remove tags).

`table` : | a GtkTextTagTable
`func` : | a function to call on each tag
`data` : | user data

### gtk_text_tag_table_get_size ()

    gint                gtk_text_tag_table_get_size         (GtkTextTagTable *table);

Returns the size of the table (number of tags)

`table` : | a GtkTextTagTable
Returns : | number of tags in `table`

## Signal Details

`texttagtable` : | the object which received the signal.
`arg1` : |
`user_data` : | user data set when the signal handler was connected.

### The `"tag-changed"` signal

    void                user_function                      (GtkTextTagTable *texttagtable,
