Thanks for the answers from Yves YANG in e4 developer mailing list.

For example:
In your example, DecoratedText have property ,text, then the widgets will be used as following:

<Composite xmlns:c="clr-namespace:ext.custom">
<c:DecoratedText text="newWidgets" />
</Composite>

and :
DecoratedText.java
------------------
package ext.custom;

public class DecoratedText {
private String text;

....

...

// event handling methods
...
}

DecoratedText.xwt
------------------
<Composite x:Class="ext.custom.DecoratedText">
<Label text={xxxxxx??}/>
<Text/>
</Composite>

How to get the property text in DecoratedText.xwt and set it into a Label or others.

Thanks

By now, you need to give them a name. and then call
XWT.findElementByName(context, "<name>");

<Composite x:Class="ext.custom.DecoratedText">
<Label name="myText" text={xxxxxx??}/>
<Text/>
</Composite>

protected void eventHandle(Object sender, Event event) {
Text text = (Text) XWT.findElementByName(event.widget, "myText");
}

We are considering to provide automatic solution to initialize the class
Field to avoid the manuel research call

Best regards
