  <title>Diálogo de progreso</title>
    <p>Use a opción <cmd>--progress</cmd> para crear un diálogo de progreso.</p>

    <p>
      <app>Zenity</app> reads data from standard input line by line. If a line is prefixed with #, the text is updated with the text on that line. If a line contains only a number, the percentage is updated with that number.
    </p>
	
    <p>O diálogo de progreso admite as seguintes opcións:</p>

    <terms>

      <item>
        <title><cmd>--text</cmd>=<var>texto</var></title>
	  <p>Especifica o texto que se mostra no diálogo de progreso.</p>
      </item>

      <item>
        <title><cmd>--percentage</cmd>=<var>porcentaxe</var></title>
	  <p>Especifica o porcentaxe inicial que se estabelece no diálogo de progreso.</p>
      </item>

      <item>
	<title><cmd>--auto-close</cmd></title>
	  <p>Pecha o diálogo de progreso cando se alcanza o 100%.</p>
      </item>

      <item>
        <title><cmd>--pulsate</cmd></title>
	  <p>Especifica que a barra de progreso pulse até que un caracter EOF se lee desde a entrada estandar.</p>
      </item>

    </terms>

    <p>O seguinte script de exemplo mostra como se crea un diálogo de progreso:</p>

<code>
#!/bin/sh
(
echo "10" ; sleep 1
echo "# Updating mail logs" ; sleep 1
echo "20" ; sleep 1
echo "# Resetting cron jobs" ; sleep 1
echo "50" ; sleep 1
echo "This line will just be ignored" ; sleep 1
echo "75" ; sleep 1
echo "# Rebooting system" ; sleep 1
echo "100" ; sleep 1
) |
zenity --progress \
  --title="Update System Logs" \
  --text="Scanning mail logs..." \
  --percentage=0

if [ "$?" = -1 ] ; then
        zenity --error \
          --text="Update canceled."
fi
</code>
