castToTextTagTable :: GObjectClass obj => obj -> TextTagTable

gTypeTextTagTable :: GType

toTextTagTable :: TextTagTableClass o => o -> TextTagTable

# Constructors

textTagTableNew :: IO TextTagTable

Creates a new `TextTagTable`. The table contains no tags by default.

# Methods

textTagTableAdd :: (TextTagTableClass self, TextTagClass tag) => self -> tag -> IO ()

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

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

textTagTableRemove :: (TextTagTableClass self, TextTagClass tag) => self -> tag -> IO ()

Remove a tag from the table.

textTagTableLookup

Arguments

:: TextTagTableClass self |
=> self |
-> String | `name` - name of a tag
-> IO (Maybe TextTag) | returns The tag, or `Nothing` if none by that name is in the table.

Look up a named tag.

textTagTableForeach :: TextTagTableClass self => self -> (TextTag -> IO ()) -> IO ()

Maps over each tag in the table.

textTagTableGetSize :: TextTagTableClass self => self -> IO Int

Returns the size of the table (the number of tags).
