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.
Returns the insets of the border.
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.
Paints the border for the specified component with the specified
position and size.
