public interface Border
Interface describing an object capable of rendering a border
around the edges of a swing component.
For examples of using borders see
How to Use Borders,
a section in The Java Tutorial.
In the Swing component set, borders supercede Insets as the
mechanism for creating a (decorated or plain) area around the
edge of a component.
Usage Notes:
- Use EmptyBorder to create a plain border (this mechanism
replaces its predecessor,
setInsets
).
- Use CompoundBorder to nest multiple border objects, creating
a single, combined border.
- Border instances are designed to be shared. Rather than creating
a new border object using one of border classes, use the
BorderFactory methods, which produces a shared instance of the
common border types.
- Additional border styles include BevelBorder, SoftBevelBorder,
EtchedBorder, LineBorder, TitledBorder, and MatteBorder.
- To create a new border class, subclass AbstractBorder.
Method Summary |
Insets |
Returns the insets of the border.
|
boolean |
Returns whether or not the border is opaque.
|
void |
Paints the border for the specified component with the specified
position and size.
|
getBorderInsets
public Insets getBorderInsets(Component c)
-
Returns the insets of the border.
- Parameters:
c
- the component for which this border insets value applies
isBorderOpaque
public boolean isBorderOpaque()
-
Returns whether or not the border is opaque. If the border
is opaque, it is responsible for filling in it's own
background when painting.
paintBorder
public void paintBorder(Component c,
Graphics g,
int x,
int y,
int width,
int height)
-
Paints the border for the specified component with the specified
position and size.
- Parameters:
c
- the component for which this border is being painted
g

x
- the x position of the painted border
y

width
- the width of the painted border
height
