[Qemu-devel] [PATCH 0/6] gtk: tweak grab handling, misc fixes.

[Gerd Hoffmann]

  Hi,

While doing some virgl testing I've trapped into a bunch of issues with
input grabs, especially in fullscreen mode.  So here is a series of
mostly grab-related patches:  Cleanups, improve tracing, don't grab when
entering fullscreen.

Also a small zoom fix, and the setlocale change discussed here recently.

please review and test,
  Gerd

Gerd Hoffmann (6):
  gtk: check for existing grabs in gd_grab_{pointer,keyboard}
  gtk: move gd_update_caption calls to
    gd_{grab,ungrab}_{pointer,keyboard}
  gtk: trace input grab reason
  gtk: set free_scale when setting zoom_fit
  gtk: don't grab input when entering fullscreen.
  gtk: setlocale for LC_MESSAGES only

[Qemu-devel] [PATCH 1/6] gtk: check for existing grabs in gd_grab_{pointer, keyboard}

[Gerd Hoffmann]

If a grab is already active for our window, do nothing.
If a grab is already active for another window, release it.

Cleanup some checks and ungrab calls in the code which are
not needed any more.

[Qemu-devel] [PATCH 2/6] gtk: move gd_update_caption calls to gd_{grab, ungrab}_{pointer, keyboard}

[Gerd Hoffmann]

Then we don't have to pair the grab/ungrab calls with update_caption
calls any more because things happen automatically ;)

[Gerd Hoffmann]

Add a reason to grab calls and trace points,
so it is easier to debug grab related ui issues.

While at it, it doesn't make sense to add reasons for ungrab too?
could be done later if needed, so

[Qemu-devel] [PATCH 4/6] gtk: set free_scale when setting zoom_fit

free_scale field tracks zoom-fit menu toggle state,
so we should keep them in sync ...

[Qemu-devel] [PATCH 5/6] gtk: don't grab input when entering fullscreen.

[Gerd Hoffmann]

Kick off all grabbing logic from fullscreen mode.  In the current state
it seems to create more problems than it solves though.  Try running
qemu/gtk fullscreen on one head of a multihead host for example ...

There probably was a reason the grab-on-fullscreen logic was added in
the first place.  So please test and report any issues so we can try to
find a sane way to handle it.

[Qemu-devel] [PATCH 6/6] gtk: setlocale for LC_MESSAGES only

[Gerd Hoffmann]

Setting other LC_* affects printf behavior and breaks QMP.
We don't have much beside menu item strings localized, so
restrict the locale setting to LC_MESSAGES.

Don't it need gtk_disable_setlocale() too? (it's marked deprecated in
gtk2, but not in gtk3 interesting)

In the previous thread, Markus suggested a fat comment, you could
place it above the call.
