          You then create a widget for each page (probably a
          container with a number of controls inside), and append
          it to the property box with <tt class="FUNCTION">
          gnome_property_box_append_page()</tt> (<a href= 
          "cha-dialogs-special.html#FL-PROPERTYBOX">Figure 8</a>).
          Its <span class="STRUCTNAME">page</span> argument is the
          widget to place inside the new notebook page, and <span
          class="STRUCTNAME">tab</span> is a widget to use on the
          notebook tab. The page number of the newly-added page is
          returned, so you don't have to keep a count yourself.
        </p>
        <p>
          It's your responsibility to keep track of any user
          interaction with the contents of each page. When the user
          changes a setting, you must notify the property box; it
          uses this information to set the "Apply" and "OK" buttons
          sensitive if and only if there are unapplied changes. The
          relevant routines are in <a href= 
          "cha-dialogs-special.html#FL-PROPBOXCHANGED">Figure
          9</a>.

          If you need to change that internal flag for some reason
          (unlikely), you can use <tt class="FUNCTION">

        <p>
          A <tt class="CLASSNAME">GnomeMessageBox</tt> is a <tt
          class="CLASSNAME">GnomeDialog</tt> subclass that conveys
          a short message or asks a simple question. Gnome provides
          several "types" of message box; they have different icons
          next to the text, and corresponding titles. The icons
          look nice, and allow users to quickly classify the
          message being presented.
        </p>
        <p>
          The API is very simple; there are no functions specific
          to <tt class="CLASSNAME">GnomeMessageBox</tt> other than
          the constructor, in <a href= 
          "cha-dialogs-special.html#FL-MSGBOX">Figure 10</a>. The
          first argument is the message to display; the second is a
          string encoding the message box type. Then you can list
          any buttons, just as you would with <tt class="FUNCTION">
          gnome_dialog_new()</tt>. Unlike the unadorned <tt class= 
          "CLASSNAME">GnomeDialog</tt>, <tt class="CLASSNAME">
          GnomeMessageBox</tt> closes on any button click by
          default. Of course you can change this behavior using <tt
          class="FUNCTION">gnome_dialog_set_close()</tt>.

          Notice that <tt class="CLASSNAME">GnomeMessageBox</tt>,
          like most <tt class="CLASSNAME">GnomeDialog</tt>
          subclasses but not <tt class="CLASSNAME">GnomeDialog</tt>
          itself, automatically closes when clicked. So there is no
          need to destroy it by hand.
