Method Detail
-
add
public void add(Block block, java.lang.Object key)
Adds a block to be managed by this instance. This method is usually called by theBlockContainer
, you shouldn't need to call it directly.- Specified by:
add
in interfaceArrangement
- Parameters:
block
- the block.key
- a key that controls the position of the block.
-
arrange
public Size2D arrange(BlockContainer container, java.awt.Graphics2D g2, RectangleConstraint constraint)
Calculates and sets the bounds of all the items in the specified container, subject to the given constraint. TheGraphics2D
can be used by some items (particularly items containing text) to calculate sizing parameters.- Specified by:
arrange
in interfaceArrangement
- 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.
-
arrangeFF
protected Size2D arrangeFF(BlockContainer container, java.awt.Graphics2D g2, RectangleConstraint constraint)
Calculates and sets the bounds of all the items in the specified container, subject to the given constraint. TheGraphics2D
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.
-
arrangeNF
protected Size2D arrangeNF(BlockContainer container, java.awt.Graphics2D g2, RectangleConstraint constraint)
Calculates and sets the bounds of all the items in the specified container, subject to the given constraint. TheGraphics2D
can be used by some items (particularly items containing text) to calculate sizing parameters.- Parameters:
container
- the container whose items are being arranged.constraint
- the size constraint.g2
- the graphics device.- Returns:
- The container size after the arrangement.
-
arrangeRR
protected Size2D arrangeRR(BlockContainer container, java.awt.Graphics2D g2, RectangleConstraint constraint)
Arranges a container with range constraints for both the horizontal and vertical.- Parameters:
container
- the container.g2
- the graphics device.constraint
- the constraint.- Returns:
- The size of the container.
-
arrangeRF
protected Size2D arrangeRF(BlockContainer container, java.awt.Graphics2D g2, RectangleConstraint constraint)
Arranges the blocks in the container using a fixed height and a range for the width.- Parameters:
