Class ColumnArrangement

public ColumnArrangement()

Creates a new instance.

public ColumnArrangement(HorizontalAlignment hAlign,
                         VerticalAlignment vAlign,
                         double hGap,
                         double vGap)

Creates a new instance.

Parameters:

hAlign - the horizontal alignment (currently ignored).

vAlign - the vertical alignment (currently ignored).

hGap - the horizontal gap.

vGap - the vertical gap.

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.

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.

protected Size2D arrangeFF(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.

Parameters:

container - the container whose items are being arranged.

g2 - the graphics device.

constraint - the size constraint.

Returns:

The container size after the arrangement.

protected Size2D arrangeNF(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.

Parameters:

container - the container whose items are being arranged.

g2 - the graphics device.

constraint - the size constraint.

Returns:

The container size after the arrangement.

protected Size2D arrangeNN(BlockContainer container,
                           Graphics2D g2)

Arranges the blocks without any constraints. This puts all blocks into a single column.

Parameters:

container - the container.

g2 - the graphics device.

Returns:

The size after the arrangement.

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

Arranges the blocks in the container using a fixed height and a range for the width.

Parameters:

container - the container.

g2 - the graphics device.

constraint - the constraint.

Returns:

The size of the container after arrangement.

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

public void clear()

Clears any cached information.

Specified by:

clear in interface Arrangement

public boolean equals(Object obj)

Tests this instance for equality with an arbitrary object.

Parameters:

obj - the object (null permitted).

Returns:

A boolean.
