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 the BlockContainer, you shouldn't need to call it directly.

Specified by:

add in interface Arrangement

---

arrange

public org.jfree.ui.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. The Graphics2D can be used by some items (particularly items containing text) to calculate sizing parameters.

Specified by:
