vaadin sampler examples and visual editing

I’ve been testing these by actually invoking them from an eclipse java class. They look impressive and I was hoping to be able to edit them visually with the vaading editor. Most of the samples are however not editable with the visual editor of vaadin as it is not an editable CustomComponent. Is there a way of encoding them so they can be edited visually or not?

Thanks

There are lots of vaadin files in sample demo application, what’s the visual design steps?

I need open those file and have a visual design.

thanks
