Class BasicBorders.SplitPaneBorder

Enclosing Class:
BasicBorders
Implemented Interfaces:
Border, UIResource

public static class BasicBorders.SplitPaneBorder
extends Object
implements Border, 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 getSplitPaneDividerBorder().

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).

Parameters:
highlight - the highlight color.
shadow - the shadow color.

Method Details

getBorderInsets

public Insets getBorderInsets(Component c)
Measures the width of this border.
Specified by:
getBorderInsets in interface Border
Parameters:

Returns:
an Insets object whose left, right, top and bottom fields indicate the width of the border at the respective edge.

isBorderOpaque

public boolean isBorderOpaque()
Determines whether this border fills every pixel in its area when painting.
Specified by:
isBorderOpaque in interface Border
Returns:
false because this border does not paint over the pixels where the divider joins the border.

                        Graphics g,
