public abstract class AbstractBorder
extends Object
implements Border, Serializable
A class that implements an empty border with no size. This provides a convenient base class from which other border classes can be easily derived.

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™JavaBeans has been added to the java.beans package. Please see XMLEncoder.

constructor:AbstractBorder() [NONE]

method:paintBorder(java.awt.Component,java.awt.Graphics,int,int,int,int) [NONE]

  • paintBorder

    public void paintBorder?(Component c, Graphics g, int x, int y, int width, int height)
    This default implementation does no painting.
    Specified by:
    paintBorder in interface Border
    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

    • method:getBorderInsets(java.awt.Component) [NONE]

    getBorderInsets

    public Insets getBorderInsets?(Component c)
    This default implementation returns a new Insets object that is initialized by the getBorderInsets(Component,Insets) method. By default the top, left, bottom, and right fields are set to 0.
    Specified by:
    getBorderInsets in interface Border
    Parameters:
    c - the component for which this border insets value applies
    Returns:
    a new Insets object

    method:getBorderInsets(java.awt.Component,java.awt.Insets) [NONE]

    getBorderInsets

    public Insets getBorderInsets?(Component c, Insets insets)
    Reinitializes the insets parameter with this Border's current Insets.
    Parameters:
    c - the component for which this border insets value applies
    insets - the object to be reinitialized
    Returns:
    the insets object

    method:isBorderOpaque() [NONE]

    isBorderOpaque

    public boolean isBorderOpaque()
    This default implementation returns false.
    Specified by:
    isBorderOpaque in interface Border
    Returns:
    false

    method:getInteriorRectangle(java.awt.Component,int,int,int,int) [NONE]

    getInteriorRectangle

    public Rectangle getInteriorRectangle?(Component c, int x, int y, int width, int height)
    This convenience method calls the static method.
    Parameters:
    c - the component for which this border is being computed
    x - the x position of the border
    y - the y position of the border
    width - the width of the border
    height - the height of the border
    Returns:
    a Rectangle containing the interior coordinates

    method:getInteriorRectangle(java.awt.Component,javax.swing.border.Border,int,int,int,int) [NONE]

    getInteriorRectangle

    public static  Rectangle getInteriorRectangle?(Component c, Border b, int x, int y, int width, int height)
    Returns a rectangle using the arguments minus the insets of the border. This is useful for determining the area that components should draw in that will not intersect the border.
    Parameters:
    c - the component for which this border is being computed
    b - the Border object
    x - the x position of the border
    y - the y position of the border
    width - the width of the border
    height - the height of the border
    Returns:
    a Rectangle containing the interior coordinates

    method:getBaseline(java.awt.Component,int,int) [NONE]

    getBaseline

    public int getBaseline?(Component c, int width, int height)
    Returns the baseline. A return value less than 0 indicates the border does not have a reasonable baseline.

    The default implementation returns -1. Subclasses that support baseline should override appropriately. If a value >= 0 is returned, then the component has a valid baseline for any size >= the minimum size and getBaselineResizeBehavior can be used to determine how the baseline changes with size.

    Parameters:
    c - Component baseline is being requested for
    width - the width to get the baseline for
    height - the height to get the baseline for
    Returns:
    the baseline or < 0 indicating there is no reasonable baseline
    Throws:
    IllegalArgumentException - if width or height is < 0
    Since:
    1.6
    See Also:
    Component.getBaseline(int,int), Component.getBaselineResizeBehavior()

    method:getBaselineResizeBehavior(java.awt.Component) [NONE]

    getBaselineResizeBehavior

    public Component.BaselineResizeBehavior getBaselineResizeBehavior?(Component c)
    Returns an enum indicating how the baseline of a component changes as the size changes. This method is primarily meant for layout managers and GUI builders.

    The default implementation returns BaselineResizeBehavior.OTHER, subclasses that support baseline should override appropriately. Subclasses should never return null; if the baseline can not be calculated return BaselineResizeBehavior.OTHER. Callers should first ask for the baseline using getBaseline and if a value >= 0 is returned use this method. It is acceptable for this method to return a value other than BaselineResizeBehavior.OTHER even if getBaseline returns a value less than 0.

    Parameters:
    c - Component to return baseline resize behavior for
    Returns:
    an enum indicating how the baseline changes as the border is resized
    Since:
    1.6
