Java UIManager-更改ComponentsStyle [英] Java UIManager - Change ComponentsStyle

问题描述

我想通过使用UIManager来更改组件样式.

I want to change my componentstyle by using UIManager.

例如:

我单击一个按钮，然后按钮前景从黑色变为绿色.对于JCheckbox也是一样.....

I click on a Button and the Button foreground changes from black to green. The same for a JCheckbox.....

在我的示例中，更改仅适用于Button.gradient....我没有获得Button.foreground的任何更新，也没有获得JCheckbox的任何更新！

In my example the changes just work for the Button.gradient.... I get no update for Button.foreground and no update for the JCheckbox!

这是我的UIManagerClass:

Here my UIManagerClass:

  package components;

import java.awt.Color;
import java.util.ArrayList;
import javax.swing.SwingUtilities;


public class OwnUiManager {

    ButtonDemo Bd;

    OwnUiManager(ButtonDemo aThis) {
        Bd = aThis;
    }

    public void setNormal() {
        ArrayList<Object> gradients = new ArrayList();
        gradients.add(0.3);
        gradients.add(0.0);
        gradients.add(new Color(221, 232, 243));
        gradients.add(new Color(255, 255, 255));
        gradients.add(new Color(184, 207, 229));
        javax.swing.UIManager.put("RadioButton.background", Color.PINK);
        javax.swing.UIManager.put("Button.gradient", gradients);
        javax.swing.UIManager.put("Button.foreground", Color.PINK);
        SwingUtilities.updateComponentTreeUI(Bd);
    }

    public void setNightVision() {
        System.out.println("Tes");
        ArrayList<Object> gradients = new ArrayList();
        gradients.add(0.18f);
        gradients.add(0.17f);
        gradients.add(Color.BLACK);
        gradients.add(Color.DARK_GRAY);
        gradients.add(Color.DARK_GRAY);
        javax.swing.UIManager.put("RadioButton.background", Color.GRAY);
        javax.swing.UIManager.put("Button.gradient", gradients);
        javax.swing.UIManager.put("Button.foreground", Color.red);

        SwingUtilities.updateComponentTreeUI(Bd);
    }
}

还有我的Buttondemo/Main-Class:

and here my Buttondemo/Main-Class:

package components;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JRadioButton;

public class ButtonDemo extends JPanel
        implements ActionListener {

    protected JButton b1,b2;
    private JRadioButton b3;

    public ButtonDemo() {

        b1 = new JButton("ON");
        b1.addActionListener(this);
        add(b1);
        b2 = new JButton("OFF");
        b2.addActionListener(this);
        add(b2);
        //For Testing the Style
        b3=new JRadioButton("Test");
        add(b3);
    }

    public void actionPerformed(ActionEvent e) {
        OwnUiManager test = new OwnUiManager(this);
        if (e.getSource().equals(b1)) {
            test.setNormal();
        } else {
            test.setNightVision();
        }
    }

    private static void createAndShowGUI() {
        JFrame frame = new JFrame("ButtonDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        ButtonDemo newContentPane = new ButtonDemo();
        newContentPane.setOpaque(true); //content panes must be opaque
        frame.setContentPane(newContentPane);
        frame.pack();
        frame.setVisible(true);
    }


    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}

推荐答案

• JCheckBox/JRadioButton具有Icon

  必须将自己的Icon更改为具体的JCheckBox/JRadioButton或将其放入UIManager，然后申请整个JVM实例

  have to change own Icon to concrete JCheckBox / JRadioButton or put then to the UIManager, then apply for whole JVM instance
