增加厚度createCompoundBorder

Question

我试图让行匹配高度（yAxis）到复合边框中心的标题。这里是一个图像，以帮助解释什么我正在寻找（仅适用于不至于箭头实际上指向）...

了一下，这里是代码...

package Main; 

import org.apache.commons.lang3.ArrayUtils; 

import java.awt.*; 
import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 

import javax.swing.*; 
import javax.swing.border.Border; 
import javax.swing.border.TitledBorder;

} 

如果有人有任何想法如何做到这一点，我会非常感谢帮助。

下面是使用MatteBorder

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

public class TestGui2 extends JFrame { 
    private static JPanel createCenterFrame() { 
    Border raisedBevel = BorderFactory.createRaisedBevelBorder(); 
    Border lineBorder = BorderFactory.createMatteBorder(10, 0, 0, 0, Color.GRAY.brighter()); 
    Border loweredBevel = BorderFactory.createLoweredBevelBorder(); 
    Border compound1 = BorderFactory.createCompoundBorder(raisedBevel, lineBorder); 
    Border compound2 = BorderFactory.createCompoundBorder(compound1, loweredBevel); 
    TitledBorder topFrameTitle = BorderFactory.createTitledBorder(compound2, "Character"); 
    topFrameTitle.setTitleJustification(TitledBorder.CENTER); 

    JPanel pnl = new JPanel(); 
    pnl.setBorder(topFrameTitle); 
    return pnl; 
    } 
    TestGui2() { 
    add(createCenterFrame(), BorderLayout.CENTER); 
    setSize(400, 175); 
    setVisible(true); 
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    } 
    public static void main(String[] args) { 
    EventQueue.invokeLater(() -> new TestGui2()); 
    } 
}
