Choosing a location to write a file to

Vaadin 6 / 7 / 8 Framework UI

I need to be able to look through the folders on a computer to choose a location to write a new file. Is there anything like a file chooser in Vaadin or a way that I can look through the folders?

Thanks

Hi,

Not built-in, no - projects quite seldom need (or want) the user to select a folder on the server. However, you should be able to build one quite easily, for instance using
FileSystemContainer
 as a container for
Tree
. Beware of all the security issues when allowing a user to browse the servers filesystem, though!

Best Regards,
Marc

What about choosing a location on the client? I want to implement two buttons in my UI, an Upload and a Download. The Upload button will obviously use the Upload component. However, I also want to be able to prompt for a location on the client machine where a file should be downloaded. Is there any kind of file prompter widget that can allow the user to pick a target directory on the client for a download? If not, is there a way to start a process of downloading that would force the client system to ask where a file should be written?

Thanks in advance,
David

I don’t think it would be very easy to allow a directory to be selected in the browser. The best you will be able to do is send a file to the browser and based on the browser the browser will allow the user to store it where it sees fit. However some browsers will just save a file to a predefined location without user intervention.
