<p>The <a class="link" href="GtkAppChooserButton.html" title="GtkAppChooserButton"><span class="type">GtkAppChooserButton</span></a> is a widget that lets the user select
an application. It implements the <a class="link" href="GtkAppChooser.html" title="GtkAppChooser"><span class="type">GtkAppChooser</span></a> interface.</p>
<p>Initially, a <a class="link" href="GtkAppChooserButton.html" title="GtkAppChooserButton"><span class="type">GtkAppChooserButton</span></a> selects the first application
in its list, which will either be the most-recently used application
or, if <a class="link" href="GtkAppChooserButton.html#GtkAppChooserButton--show-default-item" title="The “show-default-item” property"><span class="type">“show-default-item”</span></a> is <a href="https://developer.gnome.org/glib/unstable/glib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a>, the
default application.</p>
<p>The list of applications shown in a <a class="link" href="GtkAppChooserButton.html" title="GtkAppChooserButton"><span class="type">GtkAppChooserButton</span></a> includes
the recommended applications for the given content type. When
<a class="link" href="GtkAppChooserButton.html#GtkAppChooserButton--show-default-item" title="The “show-default-item” property"><span class="type">“show-default-item”</span></a> is set, the default application
is also included. To let the user chooser other applications,
