How to display GWT widgets on RootPanel?

I have a <div> in My.html file:

<html><head>
<script type="text/javascript" language="javascript" src="
 path/biz.path.nocache.js"></script></head>
 <div id = "div_test"> </div>

Now i wrote a java class which fetch the test division using Dom.

private void AddWidget() throws Exception{
 _obj = new testWidget(this._session);
 _obj.setSize("100%", "100%");
 _obj.AddTestWidget();
 RootPanel rootpanel = getViewRootPanel(div_test); // returns the division id 
 rootpanel.clear();
 rootpanel.add(_obj);   
}

and following is TestWidget.java:

public class TestWidget extends ContentContainer{
  HorizontalPanel _base = new HorizontalPanel();
  protected FlexTable _bill = new FlexTable();
  Label lblTitle;

  public TestWidget(Session s) {
    super(s);
    _base.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_LEFT);
    _base.setWidth("100%");
    initWidget(_base);
    this._session= s;
    _inheritwidget = new InheritWidget(session);
  }
  public Widget AddTestWidget() {
    System.out.println("In widget");
    lblTitle= new Label("Details");
    lblTitle.setStyleName(Resources.INSTANCE.cssElements().labelBig());
    lblTitle.getElement().getStyle().setPadding(3, Unit.PX);
    _inheritwidget .setWidget(1, 0, lblBillingTitle);
    _inheritwidget .setWidget(2, 0, billingWidget);
    _base.add(_billing);
return _base;
}
}

where InheritWidget class is extended from ContentContainer. I also check the console and it shows me In Widget. It means the flow of code is right. Please tell me what should i do to load the content of AddTestWidget in HTML div.

Is there any part which i am missing?

Solution

  • What is ContentContainer? I am unable to find it in the GWT library. Your TestWidget does not extend the GWT Widget class. Because of this, you can't use it as a widget. If you MUST extend ContentContainer for your coding needs, you can implement the GWT isWidget interface to let GWT know that it is a widget.
