JButton更改默认边框

Question

I'm using the SystemLookAndFeel which makes the default border around my buttons.

Now I would like a ticker black border, but when I set the border it just adds my new border around the default one, so I have two.

How can I change or remove the border without removing the LookAndFeel?

Also: I am using java 7 and Win 8.1

Answer 1

Work with Java 8 on Windows 10, I did this little test

As you can see, about the only method I can get to work is using setContentAreaFilled

The general problem is, many look and feels don't use the border property, but instead paint their own borders independently (hence the reason for setBorderPainted ), but the look and feel for Windows 10 just wants to be different

Try this program it has all types of borders you can have in a Jbutton

    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

Output:
