This is the ugly hack ;)
The idea is great in theory, but it'll introduce some other real-world problems.
> you just have to save the real dropbox path once (say /mnt/somedisk/Dropbox)
Do you really think that this is a great solution? - I don't think so, because it'll \
be really error-prone. It would be great if Dropbox has a command to request the \
Dropbox versioned folder path.

This is ok for FileViewDropboxPlugin::itemVersion (runs in a thread), but I think \
this is a no-go for FileViewDropboxPlugin::actions (blocks the GUI thread).

Yes I agree with you, but this has to be fixed on the Dropbox side to provide a clean \
solution for this problem.
@Frank:
What do you think?
Should we add a workaround for this problem in Dolphin?

No, this problem is (nearly) unsolvable within this plugin or within Dolphin - it can \
be fixed with some really (!!!) ugly hacks, but this will drastically slow down this \
plugin.
This needs adjustments in the Dropbox client itself.
It would be much better if Dropbox does smth. like git or svn for example, so that \
you can put every folder under version control + symlinks will also work ;)</pre> \

actually, you just have to save the real dropbox path once (say \
/mnt/somedisk/Dropbox), and then when querying some path, check if there's a symlink \
in the path's parents to the real dropbox path or one of its parents. (e.g. if you're \
in ~/Dropbox/foobar/, you check all path components from ~/Dropbox/foobar/ up, and \
find that ~/Dropbox is a symlink to /mnt/somedisk/Dropbox). then you append the part \
of the symlink to the real dropbox path (e.g. pathjoin(/mnt/Dropbox, foobar/)) and \
you're done.
that just requires to check each path component above the directory you're checking \
the status of once with .isSymLink(). neglegible. (of course you only have to check \
directories, not files)
seriously, the plugin is unusable without that functionality once you have /home/ on \
a SSD and dropbox somewhere else because don't want it creating heaps of IO, and the \
functionality isn't IO intensive or computationally expensive at all.</pre> \

This Dropbox plugin is based on the work of:
Sergei Stolyarovs - https://bitbucket.org/cancel/dolphin-dropbox-plugin
Thomas Richards - http://trichard-kde.blogspot.co.at/2010/12/introducing-dropbox-integration-for.html
What I have done:
- Ported the old source code to the newer KVersionControlPlugin2 interface
- Use the Dropbox client to form the context menu more dynamically
(If the Dropbox guys add a new feature to their client, Dolphin can make use of it \
automatically)
- Fixed a crash (Dolphin-4.8.2 segfaults when a file with special characters is \
present)
- Replaced the item version changed timer with a file system watcher -> No useless \
updates every 10 seconds and immediate update on real changes
- A lot of code/coding style related changes
I think that this plugin is small enough to include it into the official \
Dolphin-plugins collection. ;)</pre> </td>
