adding Checkboxgroup to a panel

[shree vijay]

Hi,
Is this statement valid?
topPanel.add(cbg);
topPanel is of type Panel and cbg is of type CheckboxGroup.

Hi,
Regarding the above question, i checked the api doc and found there is no add method for CheckboxGroup. Then , how do you add a CheckboxGroup object to a panel?

Hi Shree,
I just finished working my way through the AWT ;
Here's some sample code for working with Checkbox and CheckboxGroup

import java.applet.Applet;
import java.awt.*;
public class CheckboxApplet extends Applet {
    public void init() {
        setLayout(new BorderLayout() );           
        Checkbox cb1 = new Checkbox("Checkbox 1", false);
        Checkbox cb2 = new Checkbox("Checkbox 2", true);
        
        add(cb1, BorderLayout.WEST);
        add(cb2, BorderLayout.EAST);
        
        Panel p = new Panel();
        p.setLayout(new GridLayout(0,1));
        p.setBackground(Color.yellow);
        
        CheckboxGroup group = new CheckboxGroup();
        Checkbox cb3 = new Checkbox("Checkbox 3", true, group);
        Checkbox cb4 = new Checkbox("Checkbox 4", false, group);
        p.add(cb3);
        p.add(cb4);
        add(p, BorderLayout.CENTER);
        
    }
}

I don't think there is any way to add a CheckboxGroup, per se, to a container; as it is NOT a component, it inherits directly from Object. Instead, you need to create a CheckboxGroup object, and assign the individual Checkbox items to the group. Then add the Checkbox items to the panel.
Hope that helps.
