## Detailed Description

The QVBoxLayout class lines up widgets vertically.

This class is used to construct vertical box layout objects. See QBoxLayout for details.

The simplest use of the class is like this:

         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();

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 QWidget.setLayout() to install the QVBoxLayout object onto the widget. At that point, the widgets in the layout are reparented to have `window` as their parent.
