Java JButton更改默认边框

我正在使用SystemLookAndFeel，它在我的按钮周围创建默认边框

现在我想要一个黑色边框，但是当我设置边框时，它只会在默认边框周围添加我的新边框，所以我有两个

如何在不删除外观的情况下更改或删除边框

---

另外：我正在使用java 7和Win 8.1

试试这个程序，它有Jbutton中所有类型的边框

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

    public class jbuttonBoders extends JFrame {

        private JButton button[];

        private JPanel panel;

        public jbuttonBoders() {

            super("JButton Border");

            setSize(220,190);

            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

            button = new JButton[12];

            panel = new JPanel();

            panel.setLayout(new FlowLayout(FlowLayout.CENTER));

            //Constructing all 12 JButtons using "for loop"

            for(int count=0; count<button.length; count++) {

                button[count] = new JButton("Button "+(count+1));

                panel.add(button[count]);

            }



            //Setting Different Borders on each JButton

            button[0].setBorder(BorderFactory.createLineBorder(Color.blue)); // Simple Line Border

            button[1].setBorder(BorderFactory.createLineBorder(Color.red, 5)); // Line Border + Thickness of the Border

            button[2].setBorder(BorderFactory.createBevelBorder(1)); // Inner Bevel Border

            button[3].setBorder(BorderFactory.createBevelBorder(0)); // Outer Bevel Border

            button[4].setBorder(BorderFactory.createBevelBorder(1, Color.red, Color.blue)); // Two Colors Inner Bevel

            button[5].setBorder(BorderFactory.createBevelBorder(0, Color.green, Color.orange)); // Two Colors Outer Bevel

            button[6].setBorder(BorderFactory.createBevelBorder(1, Color.green, Color.orange, Color.red, Color.blue)); //Four Colors Inner Bevel

            button[7].setBorder(BorderFactory.createBevelBorder(0, Color.green, Color.orange, Color.red, Color.blue)); //Four Colors Outer Bevel

            button[8].setBorder(BorderFactory.createEmptyBorder(5,10,5,50)); // Empty Border (Upper Space, Left Space, Bottom Space, Right Space)

            button[9].setBorder(BorderFactory.createEtchedBorder(0)); //Raised Border Line

            button[10].setBorder(BorderFactory.createEtchedBorder(1)); //

            button[11].setBorder(BorderFactory.createTitledBorder("My Titled Border")); // Titled Border



            /** The Borders shown above are the basic borders that we commonly used.

             *  There are still lots of Border Styles available so all you have to do is to discover

             *  and have some experiment using all the available borders. I recommend you use JCreator Pro

             *  if want to know more about different border styles and learn how to implement them.

             */



            //Setting up the container ready for the components to be added.

            Container pane = getContentPane();

            setContentPane(pane);



            //Adding the JPanel to the container

            pane.add(panel);



            /**Set all the Components Visible.

             * If it is set to "false", the components in the container will not be visible.

             */

            setVisible(true);

        }



        //Main Method

        public static void main (String[] args) {

            jbuttonBoders jbb = new jbuttonBoders();

        }

    }


    Important Part of the Program: 

    //Setting Different Borders on each JButton

            button[0].setBorder(BorderFactory.createLineBorder(Color.blue)); // Simple Line Border

            button[1].setBorder(BorderFactory.createLineBorder(Color.red, 5)); // Line Border + Thickness of the Border

            button[2].setBorder(BorderFactory.createBevelBorder(1)); // Inner Bevel Border

            button[3].setBorder(BorderFactory.createBevelBorder(0)); // Outer Bevel Border

            button[4].setBorder(BorderFactory.createBevelBorder(1, Color.red, Color.blue)); // Two Colors Inner Bevel

            button[5].setBorder(BorderFactory.createBevelBorder(0, Color.green, Color.orange)); // Two Colors Outer Bevel

            button[6].setBorder(BorderFactory.createBevelBorder(1, Color.green, Color.orange, Color.red, Color.blue)); //Four Colors Inner Bevel

            button[7].setBorder(BorderFactory.createBevelBorder(0, Color.green, Color.orange, Color.red, Color.blue)); //Four Colors Outer Bevel

            button[8].setBorder(BorderFactory.createEmptyBorder(5,10,5,50)); // Empty Border (Upper Space, Left Space, Bottom Space, Right Space)

            button[9].setBorder(BorderFactory.createEtchedBorder(0)); //Raised Border Line

            button[10].setBorder(BorderFactory.createEtchedBorder(1)); //

            button[11].setBorder(BorderFactory.createTitledBorder("My Titled Border")); // Titled Border

对于（int count=0；count在Windows10上使用Java8，我做了这个小测试


正如您所看到的，我可以使用的唯一方法是使用
setContentAreaFilled

一般的问题是，许多外观不使用
border
属性，而是独立绘制自己的边框（这就是为什么要使用
setbOrderPaint
），但Windows 10的外观只是希望有所不同

您可能需要调整LAF。
JButton#setbordPaint
@Thomas然后uimanager.put（）方法将完成此工作？@MadProgrammer这不就是删除所有边框吗？它将（或应该）删除“边框”按钮这是由外观绘制的，但通过
setboorder
应用的边框将继续绘制否，不幸的是，正如我在上面的评论中所述，它只是删除了我自己的边框，并保留了正常工作的默认Yes，但当您放入（系统）时LAF它还使用默认边框。setContentArea（false）的部分工作正常，谢谢！我正在使用Java 7和WIndows 8.1，但仍然有效。问题是我没有使用setContentAreaFalse对：我将其设置为false，然后设置为true，这有点愚蠢……接受了你的答案，再次感谢；）
