Class FlatBorder

java.lang.Object

javax.swing.border.AbstractBorder

javax.swing.plaf.basic.BasicBorders.MarginBorder

com.formdev.flatlaf.ui.FlatBorder

All Implemented Interfaces:

FlatStylingSupport.StyleableObject, Serializable, Border, UIResource

Direct Known Subclasses:

FlatButtonBorder, FlatRoundBorder, FlatScrollPaneBorder, FlatTextBorder

public class FlatBorder
extends BasicBorders.MarginBorder
implements FlatStylingSupport.StyleableObject

Border for various components (e.g. JTextField).

There is empty space around the component border, if Component.focusWidth is greater than zero, which is used to paint outer focus border.

Because there is empty space (if outer focus border is not painted), UI delegates that use this border (or subclasses) must invoke FlatUIUtils.paintParentBackground(Graphics, JComponent) to fill the empty space correctly.
