  - ColumnArrangement
```
public ColumnArrangement(org.jfree.ui.HorizontalAlignment hAlign,
                         org.jfree.ui.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.

  - 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 org.jfree.ui.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.
  - clear
```
public void clear()
```
    Clears any cached information.
    
    Specified by:
    
    clear in interface Arrangement
  - equals
```
public boolean equals(Object obj)
```
    Tests this instance for equality with an arbitrary object.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the object (null permitted).
    
    Returns:
    
    A boolean.
