<p>
Since version 2.10, GTK+ provides the GtkAssistant widget as a replacement
for the <span class="structname">GnomeDruid</span> widget in the libgnomeui
library.
</p>
<p>
Conceptually, both <span class="structname">GtkAssistant</span> and
<span class="structname">GnomeDruid</span> do the same task, but there are
several areas where the API has been completely redesigned, so this
chapter covers the main changes between both widgets.
</p>
<div class="section">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="inserting-pages"></a>Inserting pages</h2></div></div></div>
<p>
<span class="structname">GnomeDruid</span> was implemented as a container for
<span class="structname">GnomeDruidPage</span> abstract objects, which are
implemented by the <span class="structname">GnomeDruidPageEdge</span> and
<span class="structname">GnomeDruidPageStandard</span> widgets. Instead,
<span class="structname">GtkAssistant</span> allows any widget to be a page,
and implements per-page settings (such as page type or title) as
child properties. So instead of:
</p>
<pre class="programlisting">
/* Page 1 */
page = gnome_druid_page_edge_new (GNOME_EDGE_START);
gnome_druid_page_edge_set_test (GNOME_DRUID_PAGE_EDGE (page),
"Welcome to the assistant, it will make your life easier");
gtk_widget_show (page);
gnome_druid_append_page (GNOME_DRUID (druid), GNOME_DRUID_PAGE (page));
/* Page 2 */
page = gnome_druid_page_standard_new ();
gtk_container_add (GTK_CONTAINER (GNOME_DRUID_PAGE_STANDARD (page)->vbox,
create_page1 ());
gtk_widget_show_all (page);
gnome_druid_append_page (GNOME_DRUID (druid), GNOME_DRUID_PAGE (page));
/* Page 3 */
page = gnome_druid_page_edge_new (GNOME_EDGE_FINISH);
gnome_druid_page_edge_set_test (GNOME_DRUID_PAGE_EDGE (page),
"Now you are done, your life is easier");
gtk_widget_show (page);
gnome_druid_append_page (GNOME_DRUID (druid), GNOME_DRUID_PAGE (page));
</pre>
<p>
You have to write:
</p>
<pre class="programlisting">
gtk_assistant_append_page (GTK_ASSISTANT (assistant),
gtk_label_new ("Welcome to the assistant, it will make your life easier"));
gtk_assistant_append_page (GTK_ASSISTANT (assistant),
create_page1 ());
gtk_assistant_append_page (GTK_ASSISTANT (assistant),
gtk_label_new ("Now you are done, your life is easier");
</pre>
