provide a persistent setting to select the default clipboard to synchronize

[Scott Venier]

On the win32 client, there's a setting to select which of the x11 clipboards to use for synchronization. Currently it defaults to "clipboard". I'd like to have it default to "primary". Presumably someone might want "clipboard" or "secondary". Maybe a configuration setting that persists between invocations of the client could be added?

Should work as of r10600. Mostly a client update, any recent 0.16 server builds should handle this new feature. If the server does not support enabling selections on the fly, the new options will have no effect (check added in r10603).

The new command line options are only shown when they are likely to be used:

• on win32
• with the new environment variable which can be used to specify a clipboard class (invaluable for testing on non-win32 platforms): XPRA_CLIPBOARD_CLASS="xpra.clipboard.translated_clipboard.TranslatedClipboardProtocolHelper" xpra attach ...

Tested with both Linux (via env var above) and win32, where I can now synchronize the "main" clipboard with the "PRIMARY" selection used by xterms:

xpra attach --remote-clipboard=PRIMARY ...

You can also add remote-clipboard = PRIMARY to your client's xpra.conf to make this change permanent.

@scottven: does that work for you? (fairly recent ​beta builds are available, at least for win32 clients)

Being able to switch clipboard implementations was very useful for testing, so r10636 makes it easier: the clipboard option is no longer a boolean, we support: --clipboard=translated to switch to the translated clipboard on non-win32 platforms.

@afarr: just a FYI - please close.

You may find it useful now that it works properly for synchronizing with the "PRIMARY" clipboard: makes it easier to copy things from the xterm selection buffer.

Tested real quick with 0.16.0 r10853 client v. r10854 server - and it is indeed extremely handy for copying from the xterms. Couldn't figure out how to paste back into the session with clipboard set to default though. Don't suppose I'm meant to be able to copy from a windows clipboard to a primary clipboard server-side though.

I was a little surprised (well, a tiny bit) that I couldn't highlight something in an xterm then paste into a chromium browser also within the session - but I suppose even fedora browser only paste from the clipboard clipboard?

Anyway, closing.

You can always interact with the clipboard at a low level using:

• xclip
• the clipboard tool
• with an xterm: middle click will paste the primary selection buffer

Note: I have not tested any of this because all my test systems are "clipboard challenged" (linked with synergy clipboard sharing already).

Exactly.

As of r12059, this is now also supported on OSX (#1011):
