Question

我使用GWT Editors框架进行数据绑定。我有下一个代码：

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>

如何在运行时禁用/启用firstName文本框？或者如何访问ValueBoxEditorDecorator对象的内部文本框？谁知道如何解决这个问题？提前谢谢。

不是在ValueBoxEditorDecorator上设置ui:field属性，而是在内部TextBox上设置它。然后，您可以使用以下命令禁用TextBox：

firstName.setEnabled(false);

如何禁用小部件？
