public class QVBoxLayout
extends QBoxLayout

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.
