Constructor Detail

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, 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.

Parameters: block the block. key the key (null permitted).

arrange

public Size2D arrange(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)
Arranges the blocks within the specified container, subject to the given constraint.

Parameters: container the container. constraint the constraint. g2 the graphics device.

Returns: The size following the arrangement.

arrangeFF

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.

arrangeFN

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.

arrangeFR

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. constraint the constraint. g2 the graphics device.

Returns: The size of the arrangement.

arrangeNN

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.

clear

public void clear()
Clears any cached layout information retained by the arrangement.

equals

public boolean equals(Object obj)
Compares this layout manager for equality with an arbitrary object.

Parameters: obj the object.

Returns: A boolean.
