<h2>Detailed Description</h2>
<p>The QVBoxLayout class lines up widgets vertically.</p>
<p>This class is used to construct vertical box layout objects. See <a href="qboxlayout.html">QBoxLayout</a> for details.</p>
<p>The simplest use of the class is like this:</p>
<pre>     QWidget *window = new QWidget;
     QPushButton *button1 = new QPushButton(&quot;One&quot;);
     QPushButton *button2 = new QPushButton(&quot;Two&quot;);
     QPushButton *button3 = new QPushButton(&quot;Three&quot;);
     QPushButton *button4 = new QPushButton(&quot;Four&quot;);
     QPushButton *button5 = new QPushButton(&quot;Five&quot;);

     QVBoxLayout *layout = new QVBoxLayout;
     layout-&gt;addWidget(button1);
     layout-&gt;addWidget(button2);
     layout-&gt;addWidget(button3);
     layout-&gt;addWidget(button4);
     layout-&gt;addWidget(button5);

     window-&gt;setLayout(layout);
     window-&gt;show();</pre>
<p>First, we create the widgets we want in the layout. Then, we create the QVBoxLayout object and add the widgets into the layout. Finally, we call <a href="qwidget.html#setLayout">QWidget::setLayout</a>() to install the QVBoxLayout object onto the widget. At that point, the widgets in the layout are reparented to have <tt>window</tt> as their parent.</p>
