asks, reasonably,
"When I have unsaved document in any wine application (like notepad) and
I log out or shut down the PC, Wine application doesn't offer me to save
the document, it just kills everything. Can something be done about it?"

My google-fu led me to

which led me to

Wine should probably support those somehow, and use them to notify applications
of impending system shutdown.
