Error by using code from smartGWT showcase sample

[alexoffspring]

Hi all
I'm using SmartGWT version 2.1, Eclipse SDK 3.6.

I created a Test Project to test some features i may need from smartGWT Showcase but i got an error while running in Development Mode the "Orientation" one.

The code is

import com.google.gwt.core.client.EntryPoint;
   
import com.smartgwt.client.widgets.IButton;   
import com.smartgwt.client.widgets.Img;
import com.smartgwt.client.widgets.events.ClickEvent;   
import com.smartgwt.client.widgets.events.ClickHandler;   
import com.smartgwt.client.widgets.layout.HLayout;   
import com.smartgwt.client.widgets.layout.VLayout;   
import com.smartgwt.client.widgets.tab.Tab;
import com.smartgwt.client.widgets.tab.TabSet;


public class Sample implements EntryPoint {   
  
	public void onModuleLoad() {   
		  
        
        final TabSet leftTabSet = new TabSet();
        leftTabSet.setWidth(400);   
        leftTabSet.setHeight(200);   
  
        Tab lTab1 = new Tab();   
        lTab1.setIcon("img/blu.png");   
        Img lImg1 = new Img("img/blu.png");   
        lTab1.setPane(lImg1);   
  
        Tab lTab2 = new Tab();   
        lTab2.setIcon("img/verde.png");   
        Img lImg2 = new Img("img/verde.png");   
        lTab2.setPane(lImg2);   
  
        leftTabSet.addTab(lTab1);   
        leftTabSet.addTab(lTab2);   
  
        HLayout buttons = new HLayout();   
        buttons.setMembersMargin(15);   
  
        IButton blueButton = new IButton("Select Blue");   
        blueButton.addClickHandler(new ClickHandler() {   
            public void onClick(ClickEvent event) {   
                
                leftTabSet.selectTab(0);   
            }   
        });   
  
        IButton greeButton = new IButton("Select Green");   
        greeButton.addClickHandler(new ClickHandler() {   
            public void onClick(ClickEvent event) {   
                 
                leftTabSet.selectTab(1);   
            }   
        });   
           
        buttons.addMember(greeButton);   
        buttons.addMember(blueButton);   
  
        VLayout vLayout = new VLayout();   
        vLayout.setMembersMargin(15);   
        
        vLayout.addMember(buttons);   
        vLayout.addMember(leftTabSet);   
        vLayout.setHeight("auto");   
  
        vLayout.draw();   
    }   
  
}

After launching the application on the browser i don' see the icons onto the left tabs and the images into the Panes.
Moreover i got this SGWT_WARN message:

[LOG]
00:01:05,036 [ERROR] 11:37:29.238:WARN:VLayout:isc_OID_8:ignoring bad or negative height: auto [enable 'sizing' log for stack trace] ............
[/LOG];


I guess it is related to the Images, but i don't get why.
Is it related to the path of the images?

If you remove this line:

vLayout.setHeight("auto");

The problem should go away. "auto" is not a valid height specification - you can either use a percentage or an explicit pixel height.

Thanks Paul
for the reply. Now, i don't get the exception, but i still cannot see the icons and the images.

The .png files are into an 'img' folder, which i copied in the /src client package, into the /bin client package, and into the project root.

Where am i wrong?

The icon images, by default, should be under war / images folder.
