object will be used.- Specified by:
paintBorder
in interfaceBorder
- Overrides:
paintBorder
in 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 specifiedg
isnull
-
getBorderInsets
Reinitializes theinsets
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:

c
- the component for which this border insets value appliesinsets
- theInsets
object to be reinitialized- Returns:
- the reinitialized
insets
parameter - Throws:
NullPointerException
