How disable widget?

Question

I use GWT Editors framework for data binding. I have next code:

AAAView.java

public interface AAAView extends Editor<AAA> {

public interface Presenter {
}

public interface Driver extends SimpleBeanEditorDriver<AAA, AAAViewImpl> {
}

void setPresenter(Presenter presenter);

Driver initializeDriver();

Widget asWidget();

}

AAAViewImpl.java

public class AAAViewImpl extends Composite implements AAAView {
interface AAAViewImplUiBinder extends UiBinder<Widget, AAAViewImpl> {
}

private static AAAViewImplUiBinder ourUiBinder = GWT.create(AAAViewImplUiBinder.class);

private Presenter presenter;

@UiField
ValueBoxEditorDecorator<String> firstName;
public AAAViewImpl() {
    Widget rootElement = ourUiBinder.createAndBindUi(this);
    initWidget(rootElement);
}

@Override
public void setPresenter(Presenter presenter) {
    this.presenter = presenter;
}


@Override
public Driver initializeDriver() {
    Driver driver = GWT.create(Driver.class);
    driver.initialize(this);
    return driver;
}

AAAViewImpl.ui.xml

<e:ValueBoxEditorDecorator ui:field="firstName">
<e:valuebox>
  <g:TextBox maxLength="16" width="100%"/>

  </e:valuebox>
</e:ValueBoxEditorDecorator>

How can I disable/enable firstName textbox in runtime? Or how get access to the inner textbox of ValueBoxEditorDecorator object? Anyone knows how to solve this problem? Thanks in advance.

Instead of setting the ui:field attribute on the ValueBoxEditorDecorator, set it on the inner TextBox. Then you can disable the TextBox by using:

firstName.setEnabled(false);
