[osg-users] X11 keyboard bug (+ ugly fix)

[André Garneau]

Hi Melchior,

FWIW, a fix has already been submitted to get rid of this behaviour on the
Win32 platform. The submission is still pending due to corresponding changes
being required on the Linux & OSX platforms. If you're willing to submit
your fix, we'd be one step closer to having this fixed for good...

André

X11 does, of course, tell you which modifiers are active. But only
which modifier level (shift), not which modifier key (shift_l, shift_r),
so you'd still release keys that were never pressed before. (I'm not
sure if that's really a problem, but it might be.) One would have to
keep track of every single key to avoid it.  :-/

For me *not* fixing that in OSG is not an option. But then again,
it *is* fixed for me in OSG already, so ...  :-)
