Updating text file in MultiView

[Will Hartung <wi...@gmail.com>]

I have a XMLMultiView from the generic New File Type wizard.

I'm creating the GUI form for the XML file.

How do I keep the XML file up to date after I make changes in the GUI?

Do I need to create a Saveable and put it in the lookup to mark it as
"dirty", or will that happen automatically when the XML file is updated?

Can I update the XML file only when the tabs are switched vs for every
change? In that case, I would have to add a Saveable since the XML may not
have changed yet.

Anyway, how does that workflow all work out?

Regards,

Will Hartung

Hi,
use XMLDataObject.getDocument() to access the DOM. After modifying the DOM,
you can update the file like this:

        final FileObject file = getPrimaryFile();
        file.getFileSystem().runAtomicAction(() -> {
            final FileLock l = file.lock();
            try (final OutputStream os = file.getOutputStream(l)) {
                XMLUtil.write(doc, os, "utf-8");
                //Do something to unregister the Saveable
            } finally {
                l.releaseLock();
            }
        });

Hope it helps.
Boris
