I'm using nested JSplitPane...
I want to use OneTouchExpandable, but running the code is not shown... But in preview mode I can see it.
Here complete code:

Probably you are looking for SplitPane.oneTouchButtonOffset:
import java.awt.*;
import javax.swing.*;
public class OneTouchButtonOffsetTest {
public JComponent makeUI() {
System.out.println(UIManager.getInt("SplitPane.oneTouchButtonOffset"));
UIManager.put("SplitPane.oneTouchButtonOffset", 0);
UIDefaults d = new UIDefaults();
d.put("SplitPane:SplitPaneDivider[Enabled+Vertical].foregroundPainter",
new Painter<JComponent>() {
@Override public void paint(Graphics2D g, JComponent c, int w, int h) {
/* empty */
}
});
JSplitPane splitPane = new JSplitPane();
splitPane.putClientProperty("Nimbus.Overrides", d);
splitPane.setLeftComponent(makePanel());
splitPane.setRightComponent(makePanel());
splitPane.setOneTouchExpandable(true);
JPanel p = new JPanel(new BorderLayout());
p.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
p.add(splitPane, BorderLayout.NORTH);
return p;
}
private static JComponent makePanel() {
JPanel p = new JPanel(new BorderLayout());
p.add(new JButton(), BorderLayout.WEST);
p.add(new JTextField("aaaaaaaa"));
return p;
}
public static void main(String... args) {
EventQueue.invokeLater(() -> {
try {
for (UIManager.LookAndFeelInfo laf : UIManager.getInstalledLookAndFeels()) {
if ("Nimbus".equals(laf.getName())) {
UIManager.setLookAndFeel(laf.getClassName());
}
}
} catch (Exception ex) {
ex.printStackTrace();
}
JFrame f = new JFrame();
f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
f.getContentPane().add(new OneTouchButtonOffsetTest().makeUI());
f.setSize(320, 240);
f.setLocationRelativeTo(null);
f.setVisible(true);
});
}
}

According to @aterai:
Here the code to apply to all JSplitPane's of your project
UIManager.put("SplitPane.oneTouchButtonOffset", 0);
UIDefaults uidef = new UIDefaults();
uidef.put("SplitPane:SplitPaneDivider[Enabled+Vertical].foregroundPainter",
(Painter<JComponent>) (Graphics2D g, JComponent c, int w, int h) -> { });
List<JSplitPane> listComp1 = getSpecTypeComponents(this, JSplitPane.class);
for (JSplitPane lc : listComp1) {
lc.putClientProperty("Nimbus.Overrides", uidef);
}
The code of methods used...
/**
return a List with all component according to Type class submmit
*/
private <T> List<T> getSpecTypeComponents(Container cntr,
Class<? extends javax.swing.JComponent> JCompClass) {
List<Component> lstComp = new ArrayList<>();
fillSpecTypeComponents(cntr, JCompClass, lstComp);
return (ArrayList<T>)(lstComp); // I'm not sure is bad practice...
}
/**
*/
private void fillSpecTypeComponents(Container cntr,
Class<? extends javax.swing.JComponent> JCompClass, List<Component> lstComp) {
for (Component compnnt : cntr.getComponents()) {
if (compnnt.getClass() == JCompClass) {
lstComp.add(compnnt);
}
if (Container.class.isAssignableFrom(compnnt.getClass())) {
fillSpecTypeComponents((Container) compnnt, JCompClass, lstComp);
}
}
}
