<p>
<a class="link" href="GtkAppChooser.html" title="GtkAppChooser"><span class="type">GtkAppChooser</span></a> is an interface that can be implemented by widgets which
allow the user to choose an application (typically for the purpose of
opening a file). The main objects that implement this interface are
<a class="link" href="GtkAppChooserWidget.html" title="GtkAppChooserWidget"><span class="type">GtkAppChooserWidget</span></a>, <a class="link" href="GtkAppChooserDialog.html" title="GtkAppChooserDialog"><span class="type">GtkAppChooserDialog</span></a> and <a class="link" href="GtkAppChooserButton.html" title="GtkAppChooserButton"><span class="type">GtkAppChooserButton</span></a>.
</p>
<p>
Applications are represented by GIO <span class="type">GAppInfo</span> objects here.
GIO has a concept of recommended and fallback applications for a
given content type. Recommended applications are those that claim
to handle the content type itself, while fallback also includes
applications that handle a more generic content type. GIO also
knows the default and last-used application for a given content
type. The <a class="link" href="GtkAppChooserWidget.html" title="GtkAppChooserWidget"><span class="type">GtkAppChooserWidget</span></a> provides detailed control over
whether the shown list of applications should include default,
recommended or fallback applications.
</p>
<p>
To obtain the application that has been selected in a <a class="link" href="GtkAppChooser.html" title="GtkAppChooser"><span class="type">GtkAppChooser</span></a>,
use <a class="link" href="GtkAppChooser.html#gtk-app-chooser-get-app-info" title="gtk_app_chooser_get_app_info ()"><code class="function">gtk_app_chooser_get_app_info()</code></a>.
