All Implemented Interfaces:

LayoutManager, LayoutManager2

public class SimpleGridLayout

extends Object

implements LayoutManager2

This class is a layout manager which places it's components in a grid layout. The difference from the standard grid layout is that this one adjusts the sizes of the rows/columns according to the dimensions of the components, therefore not restricting a colummn or row to a specific width/height. It also takes into account the alignment of the components when placing them into the cells
