[Qemu-devel] [PULL 0/3] gtk fixes.

[Gerd Hoffmann]

  Hi,

gtk pull second round, this time a bit shorter as I've dropped the
cleanup patches.  Lesson learned: getting them right so we still
build on all supported gtk2+3 versions isn't that easy.  There is
no reason to rush them, so lets sort that after 2.0 is out of the
door.

please pull,
  Gerd

[Qemu-devel] [PULL 1/3] gtk: Allow to activate grab-on-hover from the command line

[Gerd Hoffmann]

From: Jan Kiszka <jan.kiszka@siemens.com>

As long as we have no persistent GTK configuration, this allows to
enable the useful grab-on-hover feature already when starting the VM.

[Qemu-devel] [PULL 2/3] gtk: Fix mouse warping with gtk3

[Gerd Hoffmann]

From: Cole Robinson <crobinso@redhat.com>

We were using the wrong coordinates, this fixes things to match the
original gtk2 implementation.

You can see this error in action by using -vga qxl, however even after this
patch the mouse warps in small increments up and to the left, -7x and -3y
pixels at a time, until the pointer is warped off the widget. I think it's
a qxl bug, but the next patch covers it up.

This matches the behavior of SDL, and makes the mouse usable when
using -display gtk -vga qxl

Doesn't build if CONFIG_GTK isn't defined:

/root/qemu/vl.c:146:14: error: 'grab_on_hover' defined but not used
[-Werror=unused-variable]

Oops.  /me wonders how that escaped my attention, my mingw test build
should have hit this.  Updated pull on the way.

sorry for the trouble,
