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,
                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,
                                   java.awt.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 (null not permitted).

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 (null not permitted).

g2 - the graphics device.

Returns:

The size.

arrangeFF

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

Arranges the container with a fixed overall width and height.

Parameters:

container - the container (null not permitted).

g2 - the graphics device.

constraint - the constraint (null not permitted).

Returns:

The size following the arrangement.

arrangeFR
