To avoid any changes in input stack, we intend to use the standard
pointer support available with rotatry knob exposing event from it as
REL_WHEEL. GENIVI wayland-ivi-extension has input apis to set the
focus to specific surface with specific input device. (see:
http://wiki.projects.genivi.org/index.php/Getting_Started_with_new_Input_Handling_APIs
)

As we are using qtwayland, I found a way to disable it. I tried
disabling it using the environment variable with QT and it is working.
Attached here the patch for reference.

I would guess something different... > > How do you decide which client or surface should receive the rotary > knob events? depends: there are some devices that have a specific scroll wheel but no axes, e.g. some keyboards have that. Those devices are a pointer device (and a keyboard device). A rotary knob with no other specific function should be a buttonset devices and handled case-per-case by the compositor, but we don't have the buttonset interface yet. so far in all the use-cases we've had at least one other normal pointer device, so selecting a surface wasn't a problem.

Weston automatically creates and destroys the pointer capability and the cursor with it whether there is a pointer device connected or not. Forcing the cursor to not show would require hacking Weston core. I can't help but think that this would be a poor bandaid for the underlying problem. > I have application Qt/Qtwayland based HMI on top of weston and ivi-shell. > > > All cursors are always set by clients, either applications or in > > hmi-controller's case weston-ivi-shell-user-interface. > > I am not making use of hmi-controller and hence > weston-ivi-shell-user-interface.

That does not change the fact, that the client whose surface the pointer is on, is responsible for setting (or hiding) the cursor, when a pointer device exists. wl_pointer.set_cursor is part of Wayland core protocol and is implemented in Weston core. There are no configuration options or API to keep the cursor hidden unless you remove the whole pointer device... Hm, I suppose you could try restacking the cursor_layer behind everything else.

How to hide mouse cursor with weston and ivi-shell?
Dear All,
I would like to have the mouse pointer support available with weston
and ivi-shell (with ivi-controller.so) but want to hide the cursor
which is always visible.
Is there any easy way I can do this? Any ideas/suggestions?
** My weston.ini file for reference.Removing "cursor-theme" and
"cursor-size" doesn't help as it is used by hmi-controller adn I am
not using it.
[core]
shell=ivi-shell.so
[ivi-shell]
ivi-module=ivi-controller.so
cursor-theme=default
cursor-size=32
** I can hide if I disable the MOUSE capability via udev custom rule
but I don't want to remove the pointer support as it is required. Just
want to hide the pointer drawing.
If I remove "ENV{ID_INPUT_MOUSE}="1"" from following line cursor is no
longer visible.
SUBSYSTEM=="input", ENV{ID_INPUT}="1", ENV{ID_INPUT_TOUCHSCREEN}="1",
ENV{ID_INPUT_MOUSE}="1", ENV{ID_INPUT_KEYBOARD}="1"
Thanks & Regards,
Vikas
