columns - the column count.

public void add(Block block,
                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).

public Size2D arrange(BlockContainer container,
                      Graphics2D g2,
                      RectangleConstraint constraint)

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

Specified by:

arrange in interface Arrangement

Parameters:

container - the container.

g2 - the graphics device.

constraint - the constraint.

Returns:

The size following the arrangement.

protected Size2D arrangeFF(BlockContainer container,
                           Graphics2D g2,
                           RectangleConstraint constraint)

Arranges the container with a fixed overall width and height.

Parameters:

container - the container.

g2 - the graphics device.

constraint - the constraint.

Returns:

The size following the arrangement.

protected Size2D arrangeFN(BlockContainer container,
                           Graphics2D g2,
                           RectangleConstraint constraint)

Arrange with a fixed width and a height within a given range.

Parameters:

container - the container.

g2 - the graphics device.

constraint - the constraint.

Returns:

The size of the arrangement.

protected Size2D arrangeFR(BlockContainer container,
                           Graphics2D g2,
                           RectangleConstraint constraint)

Arrange with a fixed width and a height within a given range.

Parameters:

container - the container.

g2 - the graphics device.

constraint - the constraint.

Returns:

The size of the arrangement.

protected Size2D arrangeNN(BlockContainer container,
                           Graphics2D g2)

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

Parameters:

container - the container.

g2 - the graphics device.

Returns:

The size.

public void clear()

Clears any cached layout information retained by the arrangement.

Specified by:

clear in interface Arrangement

public boolean equals(Object obj)
