### GridArrangement

    public GridArrangement(int rows,
                           int columns)

  Creates a new grid arrangement.

  Parameters:
    `rows` - the row count.
    `columns` - the column count.

Method Detail

### add

    public void add(Block block,
                    java.lang.Object key)

  Adds a block and a key which can be used to determine the position of the block in the arrangement. This method is called by the container (you don't need to call this method directly) and gives the arrangement an opportunity to record the details if they are required.

  Specified by:
    `add` in interface `Arrangement`
  Parameters:
    `block` - the block.
    `key` - the key (`null` permitted).

### arrange

    public org.jfree.ui.Size2D arrange(BlockContainer container,
                                       RectangleConstraint constraint,
                                       java.awt.Graphics2D g2)

  Arranges the blocks within the specified container, subject to the given constraint.

  Specified by:
    `arrange` in interface `Arrangement`
  Parameters:
    `container` - the container.
    `constraint` - the constraint.
    `g2` - the graphics device.
  Returns:
    The size following the arrangement.

### arrangeNN

    protected org.jfree.ui.Size2D arrangeNN(BlockContainer container,
                                            java.awt.Graphics2D g2)

  Arranges the container with no constraint on the width or height.

  Parameters:
    `container` - the container.
    `g2` - the graphics device.
  Returns:
    The size.

### arrangeFF

    protected org.jfree.ui.Size2D arrangeFF(BlockContainer container,
                                            RectangleConstraint constraint,
                                            java.awt.Graphics2D g2)

  Arranges the container with a fixed overall width and height.

  Parameters:
    `container` - the container.
    `constraint` - the constraint.
    `g2` - the graphics device.
  Returns:
    The size following the arrangement.

### clear

    public void clear()

  Clears any cached layout information retained by the arrangement.

  Specified by:
    `clear` in interface `Arrangement`

### equals

    public boolean equals(java.lang.Object obj)

  Compares this layout manager for equality with an arbitrary object.

  Overrides:
    `equals` in class `java.lang.Object`
  Parameters:
    `obj` - the object.
  Returns:
    A boolean.
