Java中的JCheckBox可以在所有复选框中打勾

Question

I want to take off the tick from all checkbox what I have in GUI, when I pressed on button - dynamically. Is it possible?

JButton clean = new JButton("Clean");
clean.addActionListener(new MyCleanListener());
buttonBox.add(clean);

public class MyCleanListener implements ActionListener{
  public void actionPerformed(ActionEvent a){
     if(jCheckBox.isSelected())
        c.setSelected(false);
  }
}

Thank everyone for your help.

public class MyCleanListener implements ActionListener{ public void actionPerformed(ActionEvent a){ for (int i = 0; i < 256; i++){ c = checkboxList.get(i); c.setSelected(false); } } }

here my decision.

Answer 1

记住您需要在某些列表或其他数据结构中取消选中的所有复选框，然后可以在干净的侦听器的操作执行方法中对其进行迭代，并取消全部选中...

    panel.add(box1);
    panel.add(box2);
    panel.add(clean);

    clean.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            Component[] components = panel.getComponents();
            for (Component component : components) {
                if (component instanceof  JCheckBox) {
                    JCheckBox checkBox = (JCheckBox) component;
                    if(checkBox.isSelected()) {                     
                    checkBox.setSelected(false);
                    }
                }
            }
        }
    });

Get all JCheckBox components from the panel and remove selection.
