I am working with Gxt. I need to set focus to the first enabled field on the page. But I have a lot of pages and I want to centralize that behaviour. There is a lack of documentation in Gxt so I wonder if somebody has met such a problem and can help me.

Now it goes like that in each component's class

```
protected void resetFocus() {
    combobox.focus();
}

@Override
public void show() {
    super.show();
    resetFocus();
}

```

I have *found com.extjs.gxt.ui.client.aria.FocusManager* but is absolutely unclear how can I use it. Or maybe It is also possible to get chain of fields as they go on the component according to the focus. And I can move *resetFocus* method to the parent class.

Smth like that

```
protected void resetFocus() {
    *getFocusChain().get(0).focus();*
}

```
