ClickableTextRenderer-v8: A Renderer for Grid which makes a cell value clickable and look like a link. This is in particular useful for drill-down scenario, meaning where the links are internal to your application. If, on the other hand, you want to create a hyperlink in your Grid to something external from your application then there’s no need for this renderer. In that case you can simply use Vaadin’s own HtmlRenderer.
Note that drill-down was the reason why the renderer was created. It doesn’t mean the renderer cannot be used for other scenarios too.
See GitHub for more documentation and usage examples.
