TextTag

Object Hierarchy:

Description:

[ CCode ( type_id = "gtk_text_tag_get_type ()" ) ]
public class TextTag : Object

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

You may wish to begin by reading the [text widget conceptual overview](section-text-widget.html), 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 [class@Gtk.TextTagTable] for a given `GtkTextBuffer` before using them with that buffer.

[method@Gtk.TextBuffer.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.
