Introduction

CLR Class

Before explaining Spring support for XWT, it's interesting to understand how CLR Java class are managed with x:Class and x:ClassFactory.

CLR with x:Class

The Event Handling sample show you how XWT file can be linked to a Java CLR (Common Language Runtime) class to manage for instance event handler of the UI with Java code by using x:Class attribute :

<Shell xmlns="http://www.eclipse.org/xwt/presentation"
    xmlns:x="http://www.eclipse.org/xwt"
    x:Class="ui.EventHandler">
    <Shell.layout>
       <GridLayout/>
    </Shell.layout>
    <Button text="Click Me!" SelectionEvent="clickButton">
    </Button>
</Shell>

The attribute x:Class="ui.EventHandler" is linked to teh Java class ui.EventHandler :

package ui;
import org.eclipse.swt.Event;
import org.eclipse.swt.Button;
 
public class EventHandler {
    protected void clickButton(Event event) {
        Button button = (Button )event.widget;
        button.setText("Hello, world!");
    }
}

When the button gets selected, the method clickButton is invoked to change the Button text to "Hello, world!".
