<p>This class is used to construct horizontal 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("One");
QPushButton *button2 = new QPushButton("Two");
QPushButton *button3 = new QPushButton("Three");
QPushButton *button4 = new QPushButton("Four");
QPushButton *button5 = new QPushButton("Five");
QHBoxLayout *layout = new QHBoxLayout;
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 QHBoxLayout object and add the widgets into the layout. Finally, we call <a href="qwidget.html#setLayout">QWidget.setLayout</a>() to install the QHBoxLayout object onto the widget. At that point, the widgets in the layout are reparented to have <tt>window</tt> as their parent.</p>
