# Gtk TextBuffer::insert-text

since: 4.0

#### Declaration

    void
    insert_text (
      GtkTextBuffer* self,
      const GtkTextIter* location,
      gchar* text,
      gint len,
      gpointer user_data
    )

#### Description [src]

Emitted to insert text in a `GtkTextBuffer`.

Insertion actually occurs in the default handler.

Note that if your handler runs before the default handler it must not invalidate the `location` iter (or has to revalidate it). The default signal handler revalidates it to point to the end of the inserted text.

See also: `gtk_text_buffer_insert()`, `gtk_text_buffer_insert_range()`.

Default handler: The default handler is called after the handlers added via `g_signal_connect()`.
Available since: 4.0
