<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>A container which can hide its child. </p>
<p>An <a class="el" href="classGtk_1_1Expander.html" title="A container which can hide its child.">Expander</a> allows the user to hide or show its child by clicking on an expander triangle similar to the triangles used in a <a class="el" href="classGtk_1_1TreeView.html" title="The TreeView widget displays the model (Gtk::TreeModel) data and allows the user...">Gtk::TreeView</a>.</p>
<p>Normally you use an expander as you would use any other descendant of <a class="el" href="classGtk_1_1Bin.html" title="A container with just one child.">Gtk::Bin</a>; you create the child widget and use <a class="el" href="classGtk_1_1Container.html#ae5f3b9c32b1b74e7613997843e91f4cc">add()</a> to add it to the expander. When the expander is toggled, it will take care of showing and hiding the child automatically.</p>
<p>Special Usage: There are situations in which you may prefer to show and hide the expanded widget yourself, such as when you want to actually create the widget at expansion time. In this case, create an <a class="el" href="classGtk_1_1Expander.html" title="A container which can hide its child.">Expander</a> but do not add a child to it. The expander widget has an <code>expanded</code> property which can be used to monitor its expansion state. You should watch this property with a signal connection as follows: </p>
<div class="fragment"><pre class="fragment"> expander.property_expanded().signal_changed().connect(
