Hello guys.
I am reading the nice book I have just bought called ‘Learning Vaadin 7, 2nd edition’ and I have forked the githum code so that I can inspect the Twaattin application.
The way I created the application is described here (http://stackoverflow.com/questions/16073944/how-do-i-start-a-new-vaadin-project-in-intellij-idea).
So if you read this link, you’ll see that I created it manually using mvn command line and then I opened the app using my IntelliJ Idea 12 Ultimate.
Inside my com.packtpub.learnvaadin.twaattin package I see that there is an AppWidgetSet.gwt.xml with the following code :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.5.1//EN" "http://google-web-toolkit.googlecode.com/svn/tags/2.5.1/distro-source/core/src/gwt-module.dtd">
<module>
<!--
This file is automatically updated based on new dependencies by the
goal "vaadin:update-widgetset".
-->
<!-- Inherit DefaultWidgetSet -->
<inherits name="com.vaadin.DefaultWidgetSet" />
<!--
Uncomment the following to compile the widgetset for one browser only.
Multiple browsers can be specified as a comma separated list. The
supported user agents at the moment of writing were:
The value gecko1_8 is used for Firefox and safari is used for webkit
based browsers including Google Chrome.
-->
<!-- <set-property name="user.agent" value="safari"/> -->
<!--
To enable SuperDevMode, uncomment this line.
See https://vaadin.com/wiki/-/wiki/Main/Using%20SuperDevMode for more
information and instructions.
-->
<!-- <set-configuration-property name="devModeRedirectEnabled" value="true" /> -->
</module>
And the entry point class is the following :
package com.packtpub.learnvaadin.twaattin;
import javax.servlet.annotation.WebServlet;
import com.vaadin.annotations.Theme;
import com.vaadin.annotations.VaadinServletConfiguration;
import com.vaadin.server.VaadinRequest;
import com.vaadin.server.VaadinServlet;
import com.vaadin.ui.Button;
import com.vaadin.ui.Button.ClickEvent;
import com.vaadin.ui.Label;
import com.vaadin.ui.UI;
import com.vaadin.ui.VerticalLayout;
@Theme("mytheme")
@SuppressWarnings("serial")
public class TwaattinUI extends UI
{
@WebServlet(value = "/*", asyncSupported = true)
@VaadinServletConfiguration(productionMode = false, ui = TwaattinUI.class, widgetset = "com.packtpub.learnvaadin.twaattin.AppWidgetSet")
public static class Servlet extends VaadinServlet {
}
@Override
protected void init(VaadinRequest request) {
final VerticalLayout layout = new VerticalLayout();
layout.setMargin(true);
setContent(layout);
Button button = new Button("Click Me");
button.addClickListener(new Button.ClickListener() {
public void buttonClick(ClickEvent event) {
layout.addComponent(new Label("Thank you for clicking"));
}
});
layout.addComponent(button);
}
}
Looking at the github code I see that this widget set is not being used.
So I wonder why mvm creates that file and if I can tell it not to create it.
Thank you.
