Detailed Description

This class is an helper for setting the position of widgets. They are positioned along the cells of some rectangular tables. The layout may either be a single table or a tree of nested tables.

The size of a given table column can either be set manually or be chosen from the widest widget of the column. An empty column has a AUTO_DEF width, which means it will be extended so that the layout fits its minimum width.

The process is similar for table rows. By default, there is a spacing of 4 pixels between rows and between columns, and a margin of 6 pixels around the whole layout.
