<title>Méthodes utiles pour un élément graphique barre de progression</title>
<list>
<item><p>Contrairement à <code>pulse()</code>, qui fait avancer ou reculer la barre, si nous voulons que notre barre de progression se remplisse par fractions (un nombre flottant <code>float</code> compris entre <code>0.0</code> et <code>1.0</code> inclus) toujours dans le même sens, nous utilisons la méthode <code>set_fraction(fraction)</code>.</p></item>
<item><p>To set a text and show it (superimposed over the bar) use <code>set_text(<var>"text"</var>)</code> and <code>set_show_text(True)</code>. If a text is not set and <code>set_show_text(True)</code> the text will be the percentage of the work that has been completed.</p></item>
