Gtk.TextTag
Description: Reference for Gtk.TextTag

### Class

# GtkTextTag

#### Description [src]

    class Gtk.TextTag : GObject.Object
    {
      GtkTextTagPrivate* priv
    }

Can be applied to text contained in a `GtkTextBuffer`.

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.

Tags should be in the `GtkTextTagTable` for a given `GtkTextBuffer` before using them with that buffer.

`gtk_text_buffer_create_tag()` is the best way to create tags. See “gtk4-demo” for numerous examples.

For each property of `GtkTextTag`, there is a “set” property, e.g. “font-set” corresponds to “font”. These “set” properties reflect whether a property has been set or not.

They are maintained by GTK and you should not set them independently.
