public class Quaqua14LayoutStyle
A Quaqua14LayoutStyle can be queried for the preferred gaps between two JComponents, or between a JComponent and a parent Container.
To compile this class, you need the experimental SwingLayout package.

public int getPreferredGap(javax.swing.JComponent component1, javax.swing.JComponent component2, int type, int position, java.awt.Container parent)
component2
relative to component1
.
For example, the following returns the amount of space to place
between component2
and component1
when component2
is placed vertically above
component1
:
int gap = getPreferredGap(component1, component2, LayoutStyle.RELATED, SwingConstants.NORTH, parent);The
type
parameter indicates the type
of gap being requested. It can be one of the following values:
RELATED
| If the two components will be contained in
the same parent and are showing similar logically related
items, use RELATED .
|
UNRELATED
| If the two components will be
contained in the same parent but show logically unrelated items
use UNRELATED .
|
INDENT
| Used to obtain the preferred distance to indent a component
relative to another. For example, if you want to horizontally
indent a JCheckBox relative to a JLabel use INDENT .
This is only useful for the horizontal axis.
|
It's important to note that some look and feels may not distinguish
between RELATED
and UNRELATED
.
The return value is not intended to take into account the
current size and position of component2
or
component1
. The return value may take into
consideration various properties of the components. For
example, the space may vary based on font size, or the preferred
size of the component.
