VulComposer

An XML layout composer and auto-wire library for Vaadin

VulComposer is an auto-wiring composer that lets you layout Vaadin containers and components in VUL (XML) format.

Simply extend VulComposer and supply a getVulName() function, and the composer will create and layout your components according to the supplied VUL file. The composer will also auto-wire created components to those declared in your class, and will auto-wire event methods based on a simple naming convention.

Sample code

<?xml version="1.0"?>
<window caption="Test Window" width="200" scrollable="false" resizable="true" x="200" y="100">
<verticallayout sizefull="true" spacing="true" margin="bottom">
  <verticallayout orientation="horizontal" spacing="true" margin="top,left,right">
    <textfield id="testText" caption="test" width="100%"/>
    <textfield id="otherText" caption="other" width="100%"/>
  </verticallayout>
  <horizontallayout width="100%" alignment="bottom center" spacing="true">
    <horizontallayout spacing="true" alignment="middle center">
      <button id="testBtn" caption="test"/> 
      <button id="otherBtn" caption="other"/> 
    </horizontallayout>
  </horizontallayout>
</verticallayout>
</window>

package com.example.boilerplate;

import com.vaadin.Application;
import com.vaadin.ui.*;
import org.sevenless.vul.VulComposer;

public class TestComposer extends VulComposer {

  TextField testText;
  TextField otherText;
  Button testBtn;
  Button otherBtn;

  public TestComposer(Application app) throws Exception {
    super(app);
  }
    
  public String getVulName() {
    return "vul/example.vul";
  }
    
  public void onClick$testBtn(Button.ClickEvent event) {
    testText.setValue("works");
  }

  public void onClick$otherBtn(Button.ClickEvent event) {
    otherText.setValue("works too");
  }
}

...
  TestComposer tc = new TestComposer(this);
  mainWindow.addWindow((Window)tc.getRootContainer());
