GI.Gtk.Objects.TextTagTable
Description
You may wish to begin by reading the [text widget conceptual overview][TextWidget] which gives an overview of all the objects and data types related to the text widget and how they work together.
GtkTextTagTables as GtkBuildable
The GtkTextTagTable implementation of the GtkBuildable interface supports adding tags by specifying “tag” as the “type” attribute of a <child> element.
An example of a UI definition fragment specifying tags: > >class="GtkTextTagTable" > type="tag" > class="GtkTextTag"/ > /child >/object

Methods
Overloaded methods
add
Arguments
| :: (HasCallStack, MonadIO m, IsTextTagTable a, IsTextTag b) | |
| => a |
|
| -> b |
|
| -> m Bool | Returns: |
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.
foreach
Arguments
| :: (HasCallStack, MonadIO m, IsTextTagTable a) | |
| => a |
|
| -> TextTagTableForeach |
|
| -> m () |
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).
getSize
Arguments
| :: (HasCallStack, MonadIO m, IsTextTagTable a) | |
| => a |
|
| -> m Int32 | Returns: number of tags in |
Returns the size of the table (number of tags)
lookup
Arguments
| :: (HasCallStack, MonadIO m, IsTextTagTable a) | |
| => a |
|
| -> Text |
|
| -> m (Maybe TextTag) | Returns: The tag, or |
Look up a named tag.
new
Arguments
| :: (HasCallStack, MonadIO m) | |
| => m TextTagTable | Returns: a new |
Creates a new TextTagTable. The table contains no tags by
default.
remove
Arguments
| :: (HasCallStack, MonadIO m, IsTextTagTable a, IsTextTag b) | |
| => a |
|
| -> b |
|
| -> m () |
Remove a tag from the table. If a TextBuffer has table as its tag table,
the tag is removed from the buffer. The table’s reference to the tag is
removed, so the tag will end up destroyed if you don’t have a reference to
it.
