Method Detail

add

public void add(Block block,
                Object key)

Adds a block to be managed by this instance. This method is usually called by the BlockContainer, you shouldn't need to call it directly.

Specified by:

add in interface Arrangement

Parameters:

block - the block.

key - a key that controls the position of the block.

arrange

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

Calculates and sets the bounds of all the items in the specified container, subject to the given constraint. The Graphics2D can be used by some items (particularly items containing text) to calculate sizing parameters.

Specified by:

arrange in interface Arrangement

Parameters:

container - the container whose items are being arranged.

g2 - the graphics device.

constraint - the size constraint.

Returns:

The size of the container after arrangement of the contents.

arrangeFN

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

Arranges the blocks in the container with a fixed width and no height constraint.

Parameters:

container - the container.

g2 - the graphics device.

constraint - the constraint.

Returns:

The size.

arrangeFR

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

Arranges the blocks in the container with a fixed with and a range constraint on the height.

Parameters:

container - the container.

g2 - the graphics device.

constraint - the constraint.

Returns:

The size following the arrangement.

arrangeFF

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

Arranges the blocks in the container with the overall height and width specified as fixed constraints.

Parameters:

container - the container.

g2 - the graphics device.

constraint - the constraint.

Returns:

The size following the arrangement.

arrangeRR

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

Arranges the blocks with the overall width and height to fit within specified ranges.

Parameters:

container - the container.

g2 - the graphics device.

constraint - the constraint.

Returns:

The size after the arrangement.

arrangeRF

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

Arranges the blocks in the container with a range constraint on the width and a fixed height.

Parameters:

container - the container.

g2 - the graphics device.

constraint - the constraint.

Returns:

The size following the arrangement.

arrangeRN

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

Arranges the block with a range constraint on the width, and no constraint on the height.

Parameters:

container - the container.

g2 - the graphics device.
