从JTabbedPane中删除蓝色

Question

这是我第一次使用JTabbedPane。看起来，默认外观在选项卡上和组件周围显示蓝色边框边框。我如何禁用该效果？

Answer 1

那么，一个简单，快捷的方式，你可以删除这个“效果”由LookAndFeel设置为SystemLookAndFeel（或任何其他的LookAndFeel）：

UIManager.setLookAndFeel(
     UIManager.getSystemLookAndFeelClassName());

Answer 2

改变外观和 “UIManager的”

  UIManager.getLookAndFeelDefaults().put("TabbedPane:TabbedPaneTab[Enabled].backgroundPainter", new BackgroundPainter(Color.white)); 
      UIManager.getLookAndFeelDefaults().put("TabbedPane:TabbedPaneTab[Enabled+MouseOver].backgroundPainter", new BackgroundPainter(Color.white)); 
      UIManager.getLookAndFeelDefaults().put("TabbedPane:TabbedPaneTab[Enabled+Pressed].backgroundPainter", new BackgroundPainter(Color.white)); 
      UIManager.getLookAndFeelDefaults().put("TabbedPane:TabbedPaneTab[Focused+MouseOver+Selected].backgroundPainter", new BackgroundPainter(Color.white)); 
      UIManager.getLookAndFeelDefaults().put("TabbedPane:TabbedPaneTab[Focused+Pressed+Selected].backgroundPainter", new BackgroundPainter(Color.white)); 
      UIManager.getLookAndFeelDefaults().put("TabbedPane:TabbedPaneTab[Focused+Selected].backgroundPainter", new BackgroundPainter(Color.GRAY)); 
      UIManager.getLookAndFeelDefaults().put("TabbedPane:TabbedPaneTab[MouseOver+Selected].backgroundPainter", new BackgroundPainter(Color.white)); 
      UIManager.getLookAndFeelDefaults().put("TabbedPane:TabbedPaneTab[Pressed+Selected].backgroundPainter", new BackgroundPainter(Color.white)); 
      UIManager.getLookAndFeelDefaults().put("TabbedPane:TabbedPaneTab[Selected].backgroundPainter", new BackgroundPainter(Color.white)); 

BackgroundPainter类

感觉

public class BackgroundPainter implements Painter<JComponent> { 

private Color color = null; 

BackgroundPainter(Color c) { 
    color = c; 
} 

@Override 
public void paint(Graphics2D g, JComponent object, int width, int height) { 
    if (color != null) { 
     g.setColor(color); 
     g.fillRect(0, 0, width - 1, height - 1); 
    } 
} 

}
