CheckBox - Select all checkbox of a checkboxgroup

[marxan]

Hello,

I have a checkboxgroup with a couple of checkbox, what I would like to do is when the first box is checked the others should be checked too but I have no idea how to proceed to achieve that.

What I've done so far is to use a listener and I guess in my checkAll() function I should retrieve all the checkbox of the group but I don't know how to do.

Thanks for giving me some information to do that.

{
    layout: 'column',
    items: [
    {
      columnWidth: .1,
      border: 'true',
      layout: 'fit',
      items: 
      {
        xtype: 'checkboxgroup',
        id: 'group-D',
        columns: 1,
        items: [
        {    boxLabel: '<b>D</b>', 
            name: 'D',
            listeners: {
                    check: checkAll
            }
        },
        {    
            boxLabel: 'D1', 
            name: 'D1'
        },
        {    
            boxLabel: 'D2', 
            name: 'D2'
        },
        {    
            boxLabel: 'D3', 
            name: 'D3'
        },
        {    
            boxLabel: 'D4', 
            name: 'D4'
        }
        ]
        }
       }

You could use:

function checkAll(cb, checked){
  var group = Ext.getCmp('group-D');
  group.eachItem(function(item){
    item.setValue(checked);
  });
}

Thanks again Condor

If you come here, here is the code for Ext 6.6.0

function checkAll(cb, checked){
     var group = Ext.getCmp('id_annuadCheckAlphabet');
     group.eachBox(function(item){
          item.setValue(newValue);
     });
}
