You need to
before you can comment on or make changes to this bug.
The current keyboard implementation in the Windows vncviewer doesn't support
Ctrl plus AltGr characters, for example Ctrl-]. I guess most customers won't
need this, but later, we should investigate if it at all would be possible to
support such combinations.
Should work. Verify.
Successfully verified on win7 using client 3.2.0.
Does not work for me. I've tried build 3259 both on XP and Win7, both against
demo.thinlinc.com and tl.cendio.se. I've verified that "send systems keys" is
active. There's a difference between the systems, though:
* On tl.cendio.se, when pressing Ctrl-AltGr-9 I eventually get a KeyPress for
"]" with state=0x0.
* On demo.thinlinc.com, when doing as above, I get a "]" with state=0x80, which
is the same as if Ctrl was not pressed.
Checked things again. I think this is basically impossible. Windows doesn't
have a real AltGr key. If you press the actual key, Windows fakes pressing Ctrl
So I'm not sure if it is possible to separate the fake presses from the real
ones, especially when they are happening at the same time. Might be some
horrible hack that we can do though, but I pity the fool who gets that
With bug 5226 fixed, this should now be possible.
Release notes are written.
Ctrl+AltGr+<key> now works properly in most cases. We do get some (server side)
fake releases and presses in the cases where the Windows layout and server
layout differ though, but that is expected with the current model.
