[Bug 1642011] Re: Mouse wheel events not forwarded to guest using GTK display

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to another 
system. For this we need to know which bugs are still valid and which could be 
closed already. Thus we are setting all older bugs to
"Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Thank you and sorry for the inconvenience.

Title:
  Mouse wheel events not forwarded to guest using GTK display

Status in QEMU:
  Incomplete

Bug description:
  Using QEMU 2.7.0 with KVM enabled, when I launch the guest without
  options (using the default of gtk), the mouse wheel events are not
  propagated to the guest.

  When I start qemu using -display sdk, mouse wheel events are properly
  forwarded.

  I can determine that the guest is not receiving mouse wheel events by
  doing cat /dev/input/by-id/usb-QEMU_QEMU_USB_Mouse_42-event-mouse.
  When I scroll the wheel, no output is printed to the screen.

  The guest is ChromiumOS.

  The command line is:

  qemu-system-x86_64 -enable-kvm -m 2G -smp 4 -vga cirrus -usbdevice
  mouse -pidfile /tmp/kvm.pid -chardev
  pipe,id=control_pipe,path=/tmp/kvm.pipe -serial file:/tmp/kvm.serial
  -mon chardev=control_pipe -net nic,model=virtio -net
  user,hostfwd=tcp:127.0.0.1:9222-:22 -drive
  
file=chromiumos/src/build/images/amd64-generic/latest/chromiumos_qemu_image.bin,index=0,media=disk,cache=unsafe

  (Most of that invocation sets up Linux fifos for various and nefarious
  purposes and can be profitably ignored).
