Class BindableView<T>

  org.cruxframework.crux.core.client.screen.views.View
      org.cruxframework.crux.core.client.screen.views.BindableView<T>

All Implemented Interfaces:

HasOrientationChangeHandler, HasViewActivateHandlers, HasViewLoadHandlers, HasViewResizeHandlers, HasWindowCloseHandlers

public abstract class BindableView<T>
extends View

BindableViews are Views that support data binding to given data objects. You can define a BindableView using the dataObject attribute on view declaration.

 <v:view dataObject="MyDataObject">
 </gwt:textBox id="textBox1" dataBind="property1.innerProperty">
 </v:view>
 

You must annotate your Data Object with DataObject annotation.

 @DataObject("MyDataObject")
 public class MyDTO 
 {
    ...//getters and setters
 }
 

And you can access your BindableView through ViewAccessor.

 public interface Views extends ViewAccessor 
 {
    BindableView myViewId();
 }
