public class StrokeBorder extends AbstractBorder
A class which implements a border of an arbitrary stroke.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 JavaBeans™ has been added to the

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. If the border was not specified with aPaintobject, the component's foreground color will be used to render the border. If the component's foreground color is not available, the default color of theGraphicsobject will be used.- Specified by:
paintBorderin interfaceBorder- Overrides:
paintBorderin classAbstractBorder- Parameters:
c- the component for which this border is being paintedg- the paint graphicsx- the x position of the painted bordery- the y position of the painted borderwidth- the width of the painted borderheight- the height of the painted border- Throws:
NullPointerException- if the specifiedgisnull

getBorderInsets
public Insets getBorderInsets(Component c, Insets insets)
Reinitializes theinsetsparameter with this border's current insets. Every inset is the smallest (closest to negative infinity) integer value that is greater than or equal to the line width of the stroke that is used to paint the border.- Overrides:
getBorderInsetsin classAbstractBorder- Parameters:
c- the component for which this border insets value appliesinsets- theInsetsobject to be reinitialized- Returns:
- the reinitialized
insetsparameter - Throws:
NullPointerException- if the specifiedinsetsisnull- See Also:

getStroke
public BasicStroke getStroke()
Returns theBasicStrokeobject used to stroke a shape during the border rendering.- Returns:
- the
BasicStrokeobject
