<p>Various additional functions to the core API provided by the Gtk+ library.</p>
<p>For example, <a class="link" href="exo-Extensions-to-Gtk.html#exo-gtk-file-chooser-add-thumbnail-preview" title="exo_gtk_file_chooser_add_thumbnail_preview ()"><code class="function">exo_gtk_file_chooser_add_thumbnail_preview()</code></a> is a
convenience method to add a thumbnail based preview widget to a
<a href="http://developer.gnome.org/gtk2/GtkFileChooser.html"><span class="type">GtkFileChooser</span></a>, which will display a preview of the selected file if
either a thumbnail is available or a thumbnail could be generated using
the GdkPixbuf library.</p>

<p>This is a convenience function that adds a preview widget to the <em class="parameter"><code>chooser</code></em>
,
which displays thumbnails for the selected filenames using the thumbnail
database. The preview widget is also able to generate thumbnails for all
image formats supported by <span class="type">GdkPixbuf</span>.</p>
<p>Use this function whenever you display a <a href="http://developer.gnome.org/gtk2/GtkFileChooser.html"><span class="type">GtkFileChooser</span></a> to ask the user
to select an image file from the file system.</p>
<p>The preview widget also supports URIs other than file:-URIs to a certain
degree, but this support is rather limited currently, so you may want to
use <a href="http://developer.gnome.org/gtk2/GtkFileChooser.html#gtk-file-chooser-set-local-only"><code class="function">gtk_file_chooser_set_local_only()</code></a> to ensure that the user can only
select files from the local file system.</p>
<p>When <em class="parameter"><code>chooser</code></em>
 is configured to select multiple image files - using the
<a href="http://developer.gnome.org/gtk2/GtkFileChooser.html#gtk-file-chooser-set-select-multiple"><code class="function">gtk_file_chooser_set_select_multiple()</code></a> method - the behaviour of the
preview widget is currently undefined, in that it is not defined for
which of the selected files the preview will be displayed.</p>

<p>This is a convenience function, which can be registered with <a href="http://developer.gnome.org/gtk2/GtkAboutDialog.html"><span class="type">GtkAboutDialog</span></a>,
to open links clicked by the user in <a href="http://developer.gnome.org/gtk2/GtkAboutDialog.html"><span class="type">GtkAboutDialog</span></a>s.</p>
<p>All you need to do is to register this hook with <code class="function">gtk_about_dialog_set_url_hook()</code>
and <code class="function">gtk_about_dialog_set_email_hook()</code>. This can be done prior to calling
<a href="http://developer.gnome.org/gtk2/GtkAboutDialog.html#gtk-show-about-dialog"><code class="function">gtk_show_about_dialog()</code></a>, for example:</p>
<div class="informalexample"><pre class="programlisting">
static void show_about_dialog (void)
{
#if !GTK_CHECK_VERSION (2, 18, 0)
  gtk_about_dialog_set_email_hook (exo_gtk_url_about_dialog_hook, NULL, NULL);
  gtk_about_dialog_set_url_hook (exo_gtk_url_about_dialog_hook, NULL, NULL);
#endif

  gtk_show_about_dialog (.....);
}
</pre></div>
<p>This function is not needed when you use Gtk 2.18 or later, because from
that version this is implemented by default.</p>
