segmentedTextured buttons not rendered correctly

[Marco Dinacci]

Hi,

the top and bottom borders of a JToggleButton are not correctly
rendered if the client property segmentedTextured has been set.

See this screenshot: http://goo.gl/04pfw

This code reproduces the problem:

import javax.swing.*;
import java.awt.*;

public class SegmentedTexturedTest {
    public static void main(String[] args) {
        JToggleButton leftButton = new JToggleButton("Left Button");
        //leftButton.setMargin(new Insets(3,3,3,3)); // workaround
        leftButton.putClientProperty("JButton.buttonType", "segmentedTextured");
        leftButton.putClientProperty("JButton.segmentPosition", "first");
        leftButton.setFocusable(false);

        JToggleButton rightButton = new JToggleButton("Right Button");
        //rightButton.setMargin(new Insets(3,3,3,3)); // workaround
        rightButton.putClientProperty("JButton.buttonType",
"segmentedTextured");
        rightButton.putClientProperty("JButton.segmentPosition", "last");
        rightButton.setFocusable(false);

        JPanel contentPane = new JPanel(new FlowLayout(FlowLayout.LEFT, 0,0));
        contentPane.add(leftButton);
        contentPane.add(rightButton);

        JFrame frame = new JFrame("SegmentedTexturedTest");
        frame.setContentPane(contentPane);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

        frame.setVisible(true);
    }
}

The workaround (see the two commented lines above) works fine for this
simple test app but not for the more complicated layout I have in my
app as the buttons takes too much space.

Any ideas what is causing this problem ?

Thanks,
Marco
