Vaadin: open new window with ABSOLUTE url path from a BUTTON

问题

I have a table with addresses. I have a button you can click which I want to open a google search for the address in a separate window. I have tried this code with BrowserWindowOpener.

getUI().getPage().open(url, "_blank")

and

BrowserWindowOpener opener = new BrowserWindowOpener(url);
opener.extend(googleBtn)

but both are appending my url to the current path. I want to simply run a search in google in a separate window. I'm sure this is much simpler than I'm making it. It sure should be, at least. Thanks.

Brimby, you were right with your second try. The BrowserWindowOpener extension is the way to go. You should use an ExternalResource instance with an absolute URL like this:

public class OpenGoogleUI extends UI {
    @Override
    protected void init(VaadinRequest request) {
        BrowserWindowOpener extension = new BrowserWindowOpener(new ExternalResource("https://www.google.by/#q=vaadin"));
        Button button = new Button("Open Google");
        extension.extend(button);
        setContent(button);
    }
}

Try this:

// Hyperlink to a given URL
Link link = new Link("Google It",
        new ExternalResource("https://www.google.by/#q=search+query"));

// Open the URL in a new window/tab
link.setTargetName("_blank");
