Constructors Summary
SynthBorder(sun.swing.plaf.synth.SynthUI ui, Insets insets)

Methods Summary
public java.awt.InsetsgetBorderInsets(java.awt.Component c)
This default implementation returns a new Insets instance where the top, left, bottom, and right fields are set to 0.

param
c the component for which this border insets value applies
return
the new Insets object initialized to 0

 
        return getBorderInsets(c, null);
public java.awt.InsetsgetBorderInsets(java.awt.Component c, java.awt.Insets insets)
Reinitializes the insets parameter with this Border's current Insets.

param
c the component for which this border insets value applies
param
insets the object to be reinitialized
return
the insets object
