- All Known Implementing Classes:
- AbstractBorder, BasicBorders.SplitPaneBorder, BorderUIResource
- 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.
- Use EmptyBorder to create a plain border (this mechanism
replaces its predecessor,
- 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.
- See Also:
public void paintBorder(Component c,
- Paints the border for the specified component with the specified
position and size.
c - the component for which this border is being painted
g - the paint graphics
x - the x position of the painted border
y - the y position of the painted border
width - the width of the painted border
height - the height of the painted border
public Insets getBorderInsets(Component c)
- Returns the insets of the border.
c - the component for which this border insets value applies
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.
