X11 Clipboard implementation

[Mike Hearn]

Hi all,

I've been poking around inside the wine clipboard system, in an attempt
to make it properly compliant with the agreed upon specs over at 

http://www.freedesktop.org/standards/clipboards.txt

At the moment, Wine mixes up CLIPBOARD and PRIMARY, which is not a good
idea. Ideally, Wine would work like GTK, Qt, Mozilla and all the rest
do, which is to keep CLIPBOARD for ctrl-c, ctrl-v type operations, and
primary for selected text/middle click.

When you select some text in say notepad, both CLIPBOARD and PRIMARY are
grabbed, which is wrong, only primary should be grabbed. In a similar
fashion, when you select Edit | Copy only CLIPBOARD should be grabbed.

Currently, selecting text in Wine doesn't do anything (at least, not in
notepad). So, the obvious way to fix that would be to introduce a new
Wine-specific API, that lets the Wine controls call SetSelectedText or
something, which then interfaces with X.

So, I think x11drv/clipboard.c should be changed to basically eliminate
references to PRIMARY, as without the ability to deal with middle clicks
and grab-on-select, Wine has no business changing that selection.

Therefore my questions are:

1) Should I try and hack up a patch to stop wine using PRIMARY?
2) What are the rules governing new wine specific APIs. I know the DLL
Separation work is supposed to eliminate them, but there are no FAQs
anywhere on it that I can see, could somebody explain this please?

thanks -mike
