javax.swing.plaf.basic
Class BasicBorders.SplitPaneBorder

java.lang.Object
  javax.swing.plaf.basic.BasicBorders.SplitPaneBorder

All Implemented Interfaces:: javax.swing.border.Border, javax.swing.plaf.UIResource

Enclosing class:: BasicBorders

public static class BasicBorders.SplitPaneBorder
extends java.lang.Object
implements javax.swing.border.Border, javax.swing.plaf.UIResource

A border for JSplitPanes in the Basic look and feel. The divider in the middle of the JSplitPane has its own border class, of which an instance can be obtained with BasicBorders.getSplitPaneDividerBorder() 55 .

In contrast to the other borders of the Basic look and feel, this class is not serializable. While this might be unintended, GNU Classpath follows the specification in order to be fully compatible with the Sun reference implementation.

In the Sun JDK, the bottom edge of the divider also gets painted if the orientation of the enclosed JSplitPane is JSplitPane.VERTICAL_SPLIT (at least in versions 1.3.1 and 1.4.1). GNU Classpath does not replicate this bug. A report has been filed with Sun (bug ID 4885629).

Note that the bottom left pixel of the border has a different color depending on the orientation of the enclosed JSplitPane. Although this is visually inconsistent, Classpath replicates the appearance of the Sun reference implementation. A bug report has been filed with Sun (review ID 188774).
