Some comboboxes (e.g. in chrome://flags) are advertized as…
Notifications of course! Yeah, notifications, the thing that
tells you you have mail, your battery is low, or the dog has
eaten your carpet. This isn't the first time we notice Chromium's
X11 backend is pretty shit.
Anyway, added notifications and splash screens to the list of
unmanaged windows. Also removed utility windows because those
should be managed, but maybe I'm wrong and I'll revert this.
xwm.h was meant to be private, so move it to include/xwayland/xwm.h
We had an ifdef WLR_HAS_XCB_ICCCM in xwayland.h which was easy to move
to xwm, it is not safe to use the WLR_HAS_* in the public headers.
I checked a few of our current users and none rely on xwm.h being
public as expected (rootston, sway, hsroots)
Now message can look like:
[xwayland/xwm.c:991] xcb error: op ChangeProperty (no minor), code Window (no extension), value 6291465
instead of this one when the lib is not available:
[xwayland/xwm.c:999] xcb error: op 18:0, code 3, sequence 103, value 6291465
The value in case of Window is the window id, so we can tell what
function applied on which window which is a good start.
The sequence ought to be able to tell us more precisely which
invocation it was, but we never log it when calling functions
so is useless in practice and no longer logged.
gcc 6.3.0 (at least) complains about &values:
expected ‘const uint32_t * {aka const unsigned int *}’ but argument
is of type ‘uint32_t (*)[1] {aka unsigned int (*)[1]}’
Reported by thorwil on irc
This adds `wlr_xwayland_surface_is_unamanged`, to allow compositors more
fine grained control over XWayland focus.
A surface that is unmanaged should not receive focus, while other
windows that are just override redirect may want it (dmenu).
The way unamanged is determined is taken from wlc.
