Eclipse Scout download file [message #1770284]

I have a scout application that provides a download button which calls a function on the server side returning a string which I want to save (download) as a file for every user clicking on that button. What is the best way to do that with the new scout APIs?

Here is a related old forum post from 2012:

Downloading a file (actually an arbitrary byte[] array) can be implemented easily, for example you could use the following code:

BinaryResource resource = new BinaryResource("filename.txt", "Hello world".getBytes());
getDesktop().openUri(resource, OpenUriAction.DOWNLOAD);

This codes assumes that it runs within the client package and that a desktop is available, for example I used the code above on a Form. If no getDesktop() method is available you could also try IDesktop.CURRENT.get() instead.

Thank you very much, says it all.

Yesterday I found a similar example at looking at the scout widgets example code, where a jpg is stored within a table, that can be downloaded subsequently from there :)
