public class Box extends JComponent implements Accessible
The Box class can create several kinds
of invisible components
that affect layout:
glue, struts, and rigid areas.
If all the components your Box contains
have a fixed size,
you might want to use a glue component
(returned by createGlue)
to control the components' positions.
If you need a fixed amount of space between two components,
try using a strut
(createHorizontalStrut or createVerticalStrut).
If you need an invisible component
that always takes up the same amount of space,
get it by invoking createRigidArea.
If you are implementing a BoxLayout you
can find further information and examples in
How to Use BoxLayout,
a section in The Java Tutorial.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeansTM
has been added to the java.beans package.

Box(int axis)
Creates a
Box that displays its components
along the the specified axis. |
| Modifier and Type | Method and Description |
|---|---|
static Component |
createGlue()
Creates an invisible "glue" component
that can be useful in a Box
whose visible components have a maximum width
(for a horizontal box)
or height (for a vertical box).
|
static Box |
createHorizontalBox()
Creates a
Box that displays its components
from left to right. |
static Component |
createHorizontalGlue()
Creates a horizontal glue component.
|
static Component |
createHorizontalStrut(int width)
Creates an invisible, fixed-width component.
|
static Component |
createRigidArea(Dimension d)
Creates an invisible component that's always the specified size.
|
static Box |
createVerticalBox()
Creates a
Box that displays its components
from top to bottom. |
static Component |
createVerticalGlue()
Creates a vertical glue component.
|
static Component |
createVerticalStrut(int height)
Creates an invisible, fixed-height component.
|
AccessibleContext |
getAccessibleContext()
Gets the AccessibleContext associated with this Box.
|
protected void |
paintComponent(Graphics g)
Paints this
Box. |
void |
setLayout(LayoutManager l)
Throws an AWTError, since a Box can use only a BoxLayout.
