Our examples all tend to have the same structure. They follow these steps
for using a <code class="classname">Widget</code>:
</p>
<p>
</p>
<div class="orderedlist"><ol class="orderedlist" type="1">
<li class="listitem">
<p>
Declare a variable of the type of <code class="classname">Widget</code> you wish to
use, generally as member variable of a derived container class. You could also
declare a pointer to the widget type, and then create it with
<code class="literal">new</code> or <code class="function">Gtk::make_managed()</code> in your code.
</p>
</li>
<li class="listitem">
<p>
Set the attributes of the widget. If the widget has no default constructor,
then you will need to initialize the widget in the initializer list of your
container class's constructor.
</p>
</li>
<li class="listitem">
<p>
Connect any signals you wish to use to the appropriate handlers.
</p>
</li>
<li class="listitem">
<p>
Pack the widget into a container using the appropriate call,
e.g. <code class="methodname">Gtk::Box::append()</code>.
</p>
</li>
</ol></div>
<p>
</p>
<p>
If you don't want all widgets to be shown, call <code class="methodname">Gtk::Widget::set_visible(false)</code>
on the widgets that you don't want to show. If a container widget is hidden, all
of its child widgets are also hidden, even if <code class="methodname">set_visible(false)</code> is
not called on the child widgets.
