<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 class="highlightedCode brush: cpp">
QWidget *window = new QWidget;
QPushButton *button1 = new QPushButton("One");
QPushButton *button2 = new QPushButton("Two");
QPushButton *button3 = new QPushButton("Three");
QPushButton *button4 = new QPushButton("Four");
QPushButton *button5 = new QPushButton("Five");
QVBoxLayout *layout = new QVBoxLayout;
layout->addWidget(button1);
layout->addWidget(button2);
layout->addWidget(button3);
layout->addWidget(button4);
layout->addWidget(button5);
window->setLayout(layout);
window->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>
