I finally figured out how to do this in GTK so I can limit the number of accelerators that are active while keyboard grab is active. It'll be a part of v4. Regards, Anthony Liguori > > Jan

The problem is that anything that includes gtk.h would need this. I'm not sure I agree this warning has much real value in QEMU. No one submits patches using K&R declarations and I think most people are trained to explicitly use (void). The problem in GTK is gtkitemfactory.h. Specifically: /* We use () here to mean unspecified arguments. This is deprecated * as of C99, but we can't change it without breaking compatibility. * (Note that if we are included from a C++ program () will mean * (void) so an explicit cast will be needed.) */ typedef void (*GtkItemFactoryCallback) (); While deprecated in C99, it's still valid C and it's being used appropriately. Note that we require this same construct with getucontext but since it comes from a system header, it's excluded from warnings like this.

But that's only ui/gkt.c. A nice way to handle this could be to add a check to configure for GTK compatibility with -Wstrict-prototypes. Then the flag is retained if either GTK is not used or a fixed GTK appears. > > I'm not sure I agree this warning has much real value in QEMU.

Right, I had actually confused this with -Wmissing-prototypes, this flag is not so important. Looking at a5f1b965dae70f7d41721edaacb109d80721b966, there could be also function pointer declarations which the flag use may detect but otherwise I agree. > > The problem in GTK is gtkitemfactory.h.

Perhaps the real problem is that GTK is not considered a system header from compiler point of view. We could use -isystem or #pragma GCC system_header to fix it: http://gcc.gnu.org/onlinedocs/cpp/System-Headers.html The pragmas are not supported by all GCC versions though. > > Regards, > > Anthony Liguori > >> >>> >>> Regards, >>> >>> Anthony Liguori >>> >>>> >>>>> QEMU_CFLAGS="-D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE $QEMU_CFLAGS" >>>>> QEMU_INCLUDES="-I. -I\$(SRC_PATH) -I\$(SRC_PATH)/fpu" >>>>> if test "$debug_info" = "yes"; then >>>>> @@ -1635,6 +1635,23 @@ if test "$sparse" != "no" ; then >>>>> fi >>>>> >>>>> ########################################## >>>>> +# GTK probe >>>>> + >>>>> +if test "$gtk" != "no"; then >>>>> + if $pkg_config gtk+-2.0 --modversion >/dev/null 2>/dev/null && \ >>>>> + $pkg_config vte --modversion >/dev/null 2>/dev/null; then >>>>> + gtk_cflags=`$pkg_config --cflags gtk+-2.0 2>/dev/null` >>>>> + gtk_libs=`$pkg_config --libs gtk+-2.0 2>/dev/null` >>>>> + vte_cflags=`$pkg_config --cflags vte 2>/dev/null` >>>>> + vte_libs=`$pkg_config --libs vte 2>/dev/null` >>>>> + libs_softmmu="$gtk_libs $vte_libs $libs_softmmu" >>>>> + gtk="yes" >>>>> + else >>>>> + gtk="no" >>>>> + fi >>>>> +fi >>>>> + >>>>> +########################################## >>>>> # SDL probe >>>>> >>>>> # Look for sdl configuration program (pkg-config or sdl-config).

This is minimalistic and just contains the basic widget infrastructure. The GUI consists of a menu and a GtkNotebook. To start with, the notebook has its tabs hidden which provides a UI that looks very similar to SDL with the exception of the menu bar. The menu bar allows a user to toggle the visibility of the tabs. Cairo is used for rendering. I used gtk-vnc as a reference. gtk-vnc solves the same basic problems as QEMU since it was originally written as a remote display for QEMU. So for the most part, the approach to rendering and keyboard handling should be pretty solid for GTK.
