gwt custom widget with child elements configuration in UIBinder (like CustomButton)

Question

I've faced with a task to create custom widget, it has container behavior -- 3 panels inside. And i would like to use it in general UIBinder way like CustomButton

 <u:MyWidget>
   <u:image><g:Image .../></u:image>
   <u:mainContent><g:Panel.../></u:mainContent>
 </u:MyWinget>

Is it possible to define that custom child elements somehow or maybe it is predefined thing in the UIBuilder?

Thanks in advance

Correct way to do it is to use the UiChild annotation.

public class MyWidget extends Composite {
  public MyWidget() {
    // ...
  }

  @UiChild( tagname = "image" )
  void addImage(Image image) {
    // ...
  } 

  @UiChild( tagname = "mainContent" )
  void addMainContent(Widget contentWidget) {
  }
}
