[Qemu-devel] [PATCH] gtk: Support keyboard translation for hosts running Windows

[Qemu-devel] [PATCH] gtk: Support keyboard translation for hosts running Windows

[Stefan Weil]

GTK uses different hardware keycodes on Windows hosts, so some special
handling is needed to get the QEMU keycode.

Ping? Should I send a MinGW pull request for this patch?

Ping^3. What is missing to get this patch applied? It was sent more than
a month ago (2012-12-07).

You are Win32 maintainer, just send a pull request.

IIRC that symbol forces compilation for that particular Windows version
and later versions but won't work on lower versions then, right?
In that case shouldn't that live somewhere more central than gtk.c, like
QEMU_CFLAGS in configure?

Possibly handle the #ifndef MAPVK_VK_TO_VSC case?
What Windows version are we talking about anyway? XP? Vista? 7?

The MinGW include files only define MAPVK_VK_TO_VSC if _WIN32_WINNT >=
0x0601 (== _WIN32_WINNT_WIN7). By default, _WIN32_WINNT == 0x0502 (==
_WIN32_WINNT_WS03).

A more central place is fine for the future, but for now I'd prefer to
minimize potential cross effects. We already have a name conflict
between Windows macros and local QEMU macros in a file which is not
Windows related at all. Ideally, only few source files would include
Windows include file - then _WIN32_WINNT could be defined in 
include/sysemu/os-win32.h.

I have no solution for the #ifndef MAPVK_VK_TO_VSC case. The code works
for me with Windows 7 and 8.1, but might work with older versions, too.
If someone has Windows XP, a test can be run with
http://qemu.weilnetz.de/w32/qemu-w32-setup-20131128.exe. According to
MSDN, MapVirtualKey is available since Windows 2000 Professional.

I forgot to mention that the patch fixes keyboard input for QEMU running
with Wine, too. So obviously Wine supports the MapVirtualKey interface.
