  <title>TextView widget</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>
