J'utilise imbriqué JSplitPane ...JSplitPane setOneTouchExpandable (true) n'apparaît pas

Je veux utiliser OneTouchExpandable, mais l'exécution du code n'apparaît pas ... Mais en mode de prévisualisation, je peux le voir.

Il ne prend pas plus de 250 LOC pour démontrer un problème avec un seul composant! Pour une meilleure assistance plus tôt, publiez un [MCVE] ou [Short, Self Contained, Example correct] (http://www.sscce.org/). –

BTW - vous avez remarqué que les deux utilisent différents PLAF's droite? –

Copie possible de [this] (http://stackoverflow.com/q/9177182/230513). – trashgod

Probablement que vous cherchez 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);

Selon @aterai:

Voici le code à appliquer à tous JSplitPane de votre projet

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); 
}

Le code des méthodes utilisées ...

/** 
    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); 
    } 
    } 
}
