How to get the "parent" element with GWT

Say I have html part in my GWT application:

    <ul>
        <li id="tray-active"><a data-field="home">Homepage</a></li> <!-- Active page -->
        <li><a data-field="news">News</a></li>
        <li><a data-field="products">Products</a></li>
        <li><a data-field="sales">General Sales T&C</a></li>
        <li><a data-field="job">Job Opportunities</a></li>
    </ul>

And I am able to get the AnchorElement, say for the HomePage:

@Inject @DataField Anchor home;

How can I get the List li element?

Is it: home.getParent(); // which returns a widget ? Then cast it to a UListElement ? Is that it?

Update:

My main goal is to set the id of the li element to "tray-active", so when anchor item is clicked the "parent" li element is set to to "tray-active"

Solution

  • Need not to cast any thing.

    you can do this:

    home.getParent().getElement().setId("tray-active");
