/**
* Self-adjusting Container class. AdjustingContainers are an easy way to
* have Guichan position a group of widgets for you. It organizes elements
* in a table layout, with fixed columns and variable rows. The user specifies
*
* @verbitam
* <ul>
* <li>the number of columns</li>
* <li>horizontal spacing between columns</li>
* <li>vertical spacing between rows</li>
* <li>padding around the sides of the container</li>
* <li>each column's alignment</li>
* </ul>
* @endverbitam
*
* These properties give the user a lot of flexibility to make the
* widgets look just right.
* @code
* AdjustingContainer *adjust = new AdjustingContainer;
* adjust->setPadding(5, 5, 5, 5); //left, right, top, bottom
* adjust->setHorizontalSpacing(3);
* adjust->setVerticalSpacing(3);
* adjust->setColumns(3);
* adjust->setColumnAlignment(0, AdjustingContainer::LEFT);
* adjust->setColumnAlignment(1, AdjustingContainer::CENTER);
* adjust->setColumnAlignment(2, AdjustingContainer::RIGHT);
* top->add(adjust);
*
* for(int j = 0; j < 9; j++)
* {
* fcn::Label *l;
* int r = rand() % 3;
* if(r == 0)
* l = new fcn::Label("Short");
* else if(r == 1)
* l = new fcn::Label("A longer phrase");
* else
* l = new fcn::Label("Extravagent and wordy text");
* adjust->add(l);
* @endcode
*
* Output:
* @verbitam
* <pre>
*+---------------------------------------------------------------------------+
*| |
*| A longer phrase Short Extravagent and wordy text |
*| |
*| Short Extravagent and wordy text Short |
*| |
*| Short A longer phrase A longer phrase |
*| |
*+---------------------------------------------------------------------------+
* </pre>
* @endverbitam
* As you can see, each column is only as big as its largest element.
* The AdjustingContainer will resize itself and rearrange its contents
* based on whatever widgets it contains, allowing dynamic addition and
* removal while the program is running. It also plays nicely with ScrollAreas,
* allowing you to show a fixed, maximum size while not limiting the actual
* container.
*
* For more help with using AdjustingContainers, try the Guichan forums
* (http://guichan.sourceforge.net/forum/) or email mrlachatte@gmail.com.
