Hello all, I congratulate for your great work! I try this example:


package demo.app.client;

import com.extjs.gxt.ui.client.widget.ContentPanel;
import com.extjs.gxt.ui.client.widget.LayoutContainer;
import com.extjs.gxt.ui.client.widget.Viewport;
import com.extjs.gxt.ui.client.widget.layout.CenterLayout;
import com.extjs.gxt.ui.client.widget.layout.FillLayout;
import com.extjs.gxt.ui.client.widget.layout.FitLayout;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootPanel;

/**
*
* @author djesus
*/
public class App extends LayoutContainer implements EntryPoint {

/**
* The entry point method, called automatically by loading a module
* that declares an implementing class as an entry-point
*/
public void onModuleLoad() {
Viewport v = new Viewport();
v.setLayout(new FitLayout());
v.add(this);
RootPanel.get().add(v);
}

public App() {
// next line is only used to pass layout to containing container
// this will have NO effect outside of the explorer demo
setData("layout", new FillLayout());
setLayout(new CenterLayout());
ContentPanel panel = new ContentPanel();
panel.setBodyStyle("padding: 6px");
panel.setFrame(true);
panel.setHeading("CenterLayout");
panel.addText("I should be centered");
panel.setWidth(200);

add(panel);
}
}
but when run I get as show the file attached.

Is there to add any code to locate the css files?

Thanks in advance

css is part of the html file and needs to be as follows...



<link rel="stylesheet" type="text/css" href="css/ext-all.css" />
