Detailed Description

A layout manager which arranges widgets vertically.

This convenience class creates a vertical box layout, laying contained widgets out from top to bottom.

Usage example:

layout->addWidget(new Wt::WText("One"));
layout->addWidget(new Wt::WText("Two"));
layout->addWidget(new Wt::WText("Three"));
layout->addWidget(new Wt::WText("Four"));
