How to add optional parameters for ui-binder?

[membersound]

Hi,

when looking at eg VerticalPanel, I can provide optional parameters like width and height via ui-binder.

I only found @UiConstructor, but this would force the ui:binder to provide the parameters for the constructor annotated like this.
How can I create these kind of additional parameters for my own Composites?

Any attribute will call the setter for the property of the same name. Is that what you're looking for?

See http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/ui/UIObject.html

Ok I see, so just by providing setter methods I can add optional params. Thanks, exactly what I was looking for.
