Setting a buttin disabled or enabled

[localhost]

Hello all,
I have a Panel listing some emails, when the user selects a row, i have to enable a menu, when there's no selections, the menu shall remain disabled, here's my code:

    var topBar = [
    {
        text: 'Actions',
        id: 'actionsMenu',
        disabled: true,
        menu: [actionMarkAsRead, actionMarkAsUnread, actionDelete]
    },
    '->',
    'Search: ', 
    ' ',
        new Ext.app.SearchField({
            store: store,
            width: 180,
            hasSearch: true
        })
    ];

    var selectModel = new Ext.grid.CheckboxSelectionModel({
        listeners: {
            selectionchange: function() {
                if(selectModel.getCount() > 0) {
                    Ext.getCmp('actionsMenu').disabled = false;
                }
                else {
                    Ext.getCmp('actionsMenu').disabled = true;
                }
            }
        }
    });

As you can see, i have no idea how to set that set of buttons to disabled and enabled ...
anyone can help me ?

Generally when you want to perform an action on a particular object, you should look for methods rather than properties. Button shows it has enable() and disable() methods in the API docs.

thank you.
I didnt know it was a Button object since it's a simple array.

That's a little confusing because at the end of your prior post you say "button"?

Maybe this is where you needed to look?
