Constructor Detail

StrokeBorder

public StrokeBorder​(BasicStroke stroke)

Creates a border of the specified stroke. The component's foreground color will be used to render the border.

Parameters:
stroke - the BasicStroke object used to stroke a shape
Throws:
NullPointerException - if the specified stroke is null

StrokeBorder

@ConstructorProperties({"stroke","paint"})
public StrokeBorder​(BasicStroke stroke,
                    Paint paint)

Creates a border of the specified stroke and paint. If the specified paint is null, the component's foreground color will be used to render the border.

Parameters:
stroke - the BasicStroke object used to stroke a shape
paint - the Paint object used to generate a color
Throws:
NullPointerException - if the specified stroke is null

Method Detail

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 a Paint object, 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 the Graphics object will be used.

Specified by:
paintBorder in interface Border
Overrides:
paintBorder in class AbstractBorder
Parameters:
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
Throws:
NullPointerException - if the specified g is null

getBorderInsets

public Insets getBorderInsets​(Component c,
                              Insets insets)

Reinitializes the insets parameter 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:
getBorderInsets in class AbstractBorder
Parameters:
c - the component for which this border insets value applies
insets - the Insets object to be reinitialized
Returns:
the reinitialized insets parameter
Throws:
NullPointerException - if the specified insets is null

getStroke

public BasicStroke getStroke()

Returns the BasicStroke object used to stroke a shape during the border rendering.

Returns:
the BasicStroke object

getPaint

public Paint getPaint()

Returns the Paint object used to generate a color during the border rendering.

Returns:
the Paint object or null if the paint parameter is not set
