backgroundPaint

private transient java.awt.Paint backgroundPaint

The background paint.

Since:

1.0.11

container

private BlockContainer container

A container for the individual titles.

Constructor Detail

CompositeTitle

public CompositeTitle()

Creates a new composite title with a default border arrangement.

CompositeTitle

public CompositeTitle(BlockContainer container)

Creates a new title using the specified container.

getBackgroundPaint

public java.awt.Paint getBackgroundPaint()

Returns the background paint.

Returns:

The paint (possibly null).

Since:

1.0.11

Returns the container holding the titles.

Returns:

The title container (never null).

setTitleContainer

public void setTitleContainer(BlockContainer container)

Sets the title container.

Parameters:

container - the container (null not permitted).

arrange
