请教一个使按钮焦点的显示突出的问题

Question

各位达人：  
     您好！目前我用swing做界面，当按钮选中焦点的时候，焦点的显示非常不明显。目前我用的方法是在CSDN上的方法： 
     自己写一个：MyButtonUI    
    package ui; import   javax.swing.AbstractButton;  
import   javax.swing.UIManager;  
import   javax.swing.plaf.metal.MetalButtonUI;  import java.awt.Color; 
import java.awt.Font; 
import   java.awt.Graphics;  
import   java.awt.Rectangle;  public   class   MyButtonUI   extends   MetalButtonUI{          int   rectGapX;  
        int   rectGapY;  
        int   rectGapW;  
        int   rectGapH;          public   MyButtonUI()   {  
                rectGapX   =   UIManager.getInt( "ButtonUI.dashedRectGapX ");  
                rectGapY   =   UIManager.getInt( "ButtonUI.dashedRectGapY ");  
                rectGapW   =   UIManager.getInt( "ButtonUI.dashedRectGapWidth ");  
                rectGapH   =   UIManager.getInt( "ButtonUI.dashedRectGapHeight ");  
        }          protected   void   paintFocus(Graphics   g,   AbstractButton   b,   Rectangle   viewRect,    
    Rectangle   textRect,   Rectangle   iconRect)   {                  textRect   =   new   Rectangle(rectGapX+3,   rectGapY+3,   b.getWidth()-rectGapW-6,          
                                                                  b.getHeight()-rectGapH-6);             
               super.paintFocus(g,   b,   viewRect,   textRect,   iconRect);                     
        }  
}  
然后： 
JButton   button   =   new   JButton( "test   Button ");  
MyButtonUI   bui   =   new   MyButtonUI();  
button.setUI(bui); 这样的方法，可以将：焦点的边框 和 按钮的边框的距离近一些！ 
但小弟请教： 
1，是否可以将 焦点的边框 加粗 
2，是否可以将 焦点的边框 变色 
反正：目的只有一个，就是将焦点搞得醒目一些，让用户能够一眼看清楚~！！ 
大人们看是否能在上面的 MyButtonUI   上改写，或者 用其他方法来 设置button的属性！ 
谢谢了！

paintFocus里面设置颜色和线条粗细不行吗？

Answer 2

你可以用JToggleButton,然后把他们放到一个按钮组里面的啊.呵呵

简单改了一下，试试：
package component;import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.Graphics;
import java.awt.Rectangle;import javax.swing.AbstractButton;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.UIManager;import com.sun.java.swing.plaf.windows.WindowsButtonUI;public class ButtonHighlighted extends JFrame
{
    private static final long serialVersionUID = -5513217060123469552L;    JButton okButton = new JButton("OK");
    JButton hlButton = null;
    JPanel centerpiece = new JPanel();    public ButtonHighlighted()
    {
        hlButton = new JButton("Highlighted");
        hlButton.setUI(new HighlightedButtonUI());        centerpiece.setLayout(new FlowLayout());
        centerpiece.add(okButton);
        centerpiece.add(hlButton);        getContentPane().setLayout(new BorderLayout());
        getContentPane().add(centerpiece, BorderLayout.CENTER);
    }    public static void main(String[] args)
    {
        try
        {
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
        }        JFrame.setDefaultLookAndFeelDecorated(true);        ButtonHighlighted frame = new ButtonHighlighted();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(200, 100);
        frame.setLocation(200, 200);
        frame.setVisible(true);
    }    private class HighlightedButtonUI extends WindowsButtonUI
    {
        /*
        int rectGapX;
        int rectGapY;
        int rectGapW;
        int rectGapH;        public HighlightedButtonUI()
        {
            rectGapX = UIManager.getInt("ButtonUI.dashedRectGapX ");
            rectGapY = UIManager.getInt("ButtonUI.dashedRectGapY ");
            rectGapW = UIManager.getInt("ButtonUI.dashedRectGapWidth ");
            rectGapH = UIManager.getInt("ButtonUI.dashedRectGapHeight ");
        }
         */        protected void paintFocus(Graphics g, AbstractButton b, Rectangle viewRect, Rectangle textRect,
                Rectangle iconRect)
        {
            //textRect = new Rectangle(rectGapX + 3, rectGapY + 3, b.getWidth() - rectGapW - 6, b.getHeight() - rectGapH
            //        - 6);            Rectangle focusRect = new Rectangle();
            String text = b.getText();
            if (text != null)
            {
                focusRect.setBounds(textRect);
            }
            else
            {
                focusRect.setBounds(iconRect);
            }            g.setColor(Color.RED);
            g.drawRect(focusRect.x - 1, focusRect.y - 1, focusRect.width + 1, focusRect.height + 1);            super.paintFocus(g, b, viewRect, textRect, iconRect);
        }
    }
}

上面的突出显示是把文字框起来了，用你原来的方法可以将按钮整个框起来，只需要稍微调整一下：
    private class HighlightedButtonUI extends WindowsButtonUI
    {
        int rectGapX;
        int rectGapY;
        int rectGapWidth;
        int rectGapHeight;        public HighlightedButtonUI()
        {
            rectGapX = UIManager.getInt("ButtonUI.dashedRectGapX");
            rectGapY = UIManager.getInt("ButtonUI.dashedRectGapY");
            rectGapWidth = UIManager.getInt("ButtonUI.dashedRectGapWidth");
            rectGapHeight = UIManager.getInt("ButtonUI.dashedRectGapHeight");
        }        protected void paintFocus(Graphics g, AbstractButton b, Rectangle viewRect, Rectangle textRect,
                Rectangle iconRect)
        {
            //textRect = new Rectangle(rectGapX + 3, rectGapY + 3, b.getWidth() - rectGapW - 6, b.getHeight() - rectGapH
            //        - 6);            g.setColor(Color.RED);
            g.drawRect(rectGapX + 1, rectGapY + 1, b.getWidth() - rectGapWidth - 3, b.getHeight() - rectGapHeight - 3);            super.paintFocus(g, b, viewRect, textRect, iconRect);
        }
    }
