/*! \class WBorderLayout Wt/WBorderLayout Wt/WBorderLayout
* \brief A layout manager which divides the container region in five regions.
*
* The five regions are composed of:
* <pre>
------------------------------------
| North |
------------------------------------
| | | |
| West | Center | East |
| | | |
------------------------------------
| South |
------------------------------------
* </pre>
*
* Each region may hold no more than one widget, and for all but the
* Center region, the widget is optional.
*
* The North, West, East, and South widgets will take their preferred
* sizes, while the Center widget takes all available remaining space.
*
* \if cpp
* Usage example:
* \code
* Wt::WContainerWidget *w = new Wt::WContainerWidget(this);
* Wt::WBorderLayout *layout = new Wt::WBorderLayout();
* layout->addWidget(new Wt::WText("West-side is best"), Wt::West);
* layout->addWidget(new Wt::WText("East-side is best"), Wt::East);
* layout->addWidget(contents, Wt::Center);
*
* // use layout but do not justify vertically
* w->setLayout(layout, Wt::AlignTop | Wt::AlignJustify);
* \endcode
* \endif
