请教下swing中怎么遍历checkbox控件并获取它们的值

Answer 1

什么叫遍历jcheckbox?
你的需求或者说你想要达到什么样的目的，现在你又是如何组织的？
描述的详细些吧

Answer 2

public static ArrayList<JCheckBox> getAllJCheckBox(Container ct, ArrayList<JCheckBox> list){
if(list==null){
list=new ArrayList<JCheckBox>();
}
int count=ct.getComponentCount();
for(int i=0;i<count;i++){
Component c=ct.getComponent(i);
if(c instanceof JCheckBox){
list.add((JCheckBox)c);
}
else if(c instanceof Container){
getAllJCheckBox((Container)c,list);
}
}
return list;
}
Container ct你可以传任意的Swing组件  比如:JFrame JPanel 等等

    ArrayList<JCheckBox> 是引用什么包的 怎么我贴过去报错

Answer 4

import java.awt.Component;
import java.awt.Container;
import java.util.ArrayList;
import javax.swing.JCheckBox;

Answer 5

引用了之后就好了 但是我要获取到所有JCHECKBOX的值的话怎么写？

Answer 6

改改就行了    public static ArrayList<Boolean> getAllJCheckBoxValue(Container ct, ArrayList<Boolean> list){
        if(list==null){
            list=new ArrayList<Boolean>();
        }
        int count=ct.getComponentCount();
        for(int i=0;i<count;i++){
            Component c=ct.getComponent(i);
            if(c instanceof JCheckBox){
                list.add(((JCheckBox)c).isSelected());
            }
            else if(c instanceof Container){
             getAllJCheckBoxValue((Container)c,list);
            }
        }
        return list;
    }

Answer 7

        Component[] cs = panel.getComponents();        
        List<JCheckBox> checkBoxs = new ArrayList<JCheckBox>();
        for(Component c:cs){
            if(c instanceof JCheckBox){
                JCheckBox checkBox=((JCheckBox)c);
                checkBoxs.add(checkBox);
            }
        }
        
        for(JCheckBox box:checkBoxs){
            checkBox.get……
              checkBox.isSelected();
        }

Answer 8

是不是要将checkBox放到一个Buttongroup 里面，然后用buttongroup.getselect().getActionName();就可以得到选中 的值

Answer 9

当然要给checkBox.setActionName();就可以得到你设置的值了；
