从另一个按钮更改切换按钮的状态

I'm creating a Java GUI using Swing with Eclipse and Window Builder Pro. I'm using JButtons and JToggleButtons. I want to change toggle button's state from another button.

我正在使用Swing with Eclipse和Window Builder Pro创建Java GUI。我正在使用JButtons和JToggleButtons。我想从另一个按钮更改切换按钮的状态。

For example, when I click the clear grid, all the toggle buttons will be 'not selected'.

例如，当我单击清除网格时，所有切换按钮都将被“未选中”。

How can I do this? What are the methods that I have to use for toggle buttons and buttons?

我怎样才能做到这一点？我必须使用哪些方法来切换按钮和按钮？

toggleButton.setSelected(boolean b)

toggleButton.setSelected（boolean b）

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.AbstractButton;
import javax.swing.JFrame;
import javax.swing.JToggleButton;

public class JToggleButtonAction {

    public static void main(String args[]) {
        JFrame frame = new JFrame("Selecting Toggle");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JToggleButton toggleButton = new JToggleButton("Toggle Button");
        final JToggleButton toggleButton1 = new JToggleButton("Another Toggle Button");
        ActionListener actionListener = new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent actionEvent) {
                AbstractButton abstractButton = (AbstractButton) actionEvent.getSource();
                boolean selected = abstractButton.getModel().isSelected();
                System.out.println("Action - selected=" + selected + "\n");
                toggleButton1.setSelected(selected);
            }
        };
        toggleButton.addActionListener(actionListener);
        frame.add(toggleButton, BorderLayout.NORTH);
        frame.add(toggleButton1, BorderLayout.SOUTH);
        frame.pack();
        frame.setVisible(true);
    }
}

Add actionListener to your JButton and in actionPerformed(ActionEvent) method change the state of all JToggleButtons. Make sure all your JToggleButton is accessible in this method. A simple example will be..

将actionListener添加到JButton并在actionPerformed（ActionEvent）方法中更改所有JToggleButtons的状态。确保在此方法中可以访问所有JToggleButton。一个简单的例子就是......

    JFrame frame = new JFrame("Panel image demo");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400, 400);
    frame.setLayout(new FlowLayout());

    final JToggleButton[] button = new JToggleButton[10];
    for (int i = 0; i < button.length; i++) {
        button[i] = new JToggleButton("Toggle Us");
        frame.add(button[i]);
    }
    JButton jButton = new JButton("Toggle that button");
    jButton.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            for (JToggleButton jToggleButton : button) {
                jToggleButton.setSelected(!jToggleButton.isSelected()); // <-- this will change the state of toggle button
            }
        }
    });

    frame.add(jButton);
    frame.setVisible(true);

Register an ActionListener to the JButton instance and make sure you can access the toggle buttons therein to manipulate their state.

将ActionListener注册到JButton实例，并确保您可以访问其中的切换按钮来操纵它们的状态。

i was looking for this, this might help somebody out

我正在寻找这个，这可能会帮助别人

B1.setSelected(false);

i made a method that make all my button false (unselect the toggles when i wanted it)

我做了一个方法，使我的所有按钮都是假的（当我需要时取消选择切换）
