Quick little override to support a headerTip:

Code:

---

Ext.define('Override.selection.CheckboxModel', {
    override : 'Ext.selection.CheckboxModel',

    headerTip : 'Select All',

    getHeaderConfig : function() {
        var ret      = this.callOverridden(arguments),
            headerTip = this.headerTip;

        if (headerTip) {
            ret.text = '<div data-qtip="' + headerTip + '" style="width:100%;height:100%;">&nbsp;</div>';
        }

        return ret;
    }
});

---

worked like a charm... Thanks
