Creates a new instance.

Method Summary

void
add(Block block, Object key)
Adds a block to the arrangement manager at the specified edge.
Size2D
arrange(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)
Arranges the items in the specified container, subject to the given constraint.
protected Size2D
arrangeFF(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)
Arranges the items within a container.
protected Size2D
arrangeFN(BlockContainer container, Graphics2D g2, double width)
Arranges the container width a fixed width and no constraint on the height.
protected Size2D
arrangeFR(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)
Performs an arrangement with a fixed width and a range for the height.
protected Size2D
arrangeNN(BlockContainer container, Graphics2D g2)
Performs an arrangement without constraints.
protected Size2D
arrangeRR(BlockContainer container, Range widthRange, Range heightRange, Graphics2D g2)
Performs an arrangement with range constraints on both the vertical and horizontal sides.
void
clear()
Clears the layout.
boolean
equals(Object obj)
Tests this arrangement for equality with an arbitrary object.
