Creating Tab Panel using GWT

     

This example describes the Basics for building the Tab Panel using GWT. The steps involved in Building the Tab Panel are described below:-

final Label label = new Label("Click the Tab below to view content")
Here we are declaring label. Label is a widget that contains text.

TabPanel tp = new TabPanel()
Here we are creating object of TabPanel class. TabPanel  is a panel that represents a tabbed set of pages, each of which contains another widget.

HTML index = new HTML("Tab you have selected is Index.")
Creating an object of class HTML named index. HTML is a widget that can contain arbitrary HTML.

tp.add(index, "Index ")
This is a method of Tab Panel class for adding a widget to the tab panel.

RootPanel.get().add(tp)
By this method we are adding label to the root panel. Root panel is a panel to which all other widgets must  be added. it is not created directly.

TabPanelEx.java

package org.yournamehere.client;

import com.google.gwt.user.client.ui.HTML;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.TabPanel;
import com.google.gwt.user.client.ui.RootPanel;

public class TabPanelEx {

  public void onModuleLoad() {
  final Label label = new 
 
Label("Click the Tab below to view content");
  final Label label1 = new 
 
Label("   ");
  
  TabPanel tp = new TabPanel();
  tp.setWidth("200px");
  HTML index1 = new HTML("");
  HTML index = new HTML("Tab you have selected is Index.");
  tp.add(index, "Index ");

  HTML homeText = new HTML("Tab you have selected is Home.");
  tp.add(homeText, " Home  ");

  HTML moreInfo = new
    
HTML("Tab you have selected is MoreInfo.");
  tp.add(moreInfo, "  MoreInfo  ");
  tp.selectTab(0);
  RootPanel.get().add(label);
  RootPanel.get().add(label1);
  RootPanel.get().add(tp);

  }
}
