  <title>Widget TextView</title>
     <note style="sidebar"><p>If we press "enter", we have a new line.</p>
     <p>If we press "enter" more times then there are lines in the default sized window, then a vertical scrollbar appears.</p>
     <p>If we write a long sentence, the text will wrap breaking lines between words.</p>
     <p>If we have a loooooooooooooooooooooooooooooooooooong word, a horizontal scrollbar will appear.</p></note>

    <p>This is an example of Gtk.TextView</p>

		Object (application: app, title: "TextView Example");
		this.set_default_size (220, 200);

		var buffer = new Gtk.TextBuffer (null); //stores text to be displayed
		var textview = new Gtk.TextView.with_buffer (buffer); //displays TextBuffer
		textview.set_wrap_mode (Gtk.WrapMode.WORD); //sets line wrapping

		var scrolled_window = new Gtk.ScrolledWindow (null, null);
		scrolled_window.set_policy (Gtk.PolicyType.AUTOMATIC,
		                            Gtk.PolicyType.AUTOMATIC);
