I'm trying to find a way to make input in ckeditor dialog readonly.

I have initialized elements like this:

```
type: 'hbox',
widths: ['25%', '75%'],
children:
    [{
        type: 'text',
        id: 'moduleId',
        label: 'Module',

```

Looking in [documentation](http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.dialog.definition.uiElement.html) I guess the only way is to apply some css style to input?
