public class DragGridPanel

extends javax.swing.JPanel

implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.ComponentListener, java.awt.event.FocusListener, java.awt.event.ContainerListener

A Panel which is divided into a rectangular grid which the user can change. Components may be added to the grid, and may take up any rectangular set of cells within the grid. The user may drag the borders between the components to change the relative sizes of the cells, and thus the sizes of the components.
