TextBuffer

open class TextBuffer(pointer: <Error class: unknown class><<Error class: unknown class>>)

Stores text and attributes for display in a GtkTextView.

You may wish to begin by reading the 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.

GtkTextBuffer can support undoing changes to the buffer content, see method@Gtk.TextBuffer.set_enable_undo.
