kchibisov, I would always recommend client code to ack a configure from the draw path, and not from the event received code.
<pq>
kchibisov, I consider sending the ack from event configure handler a poor code design.
<pq>
*from the configure event handler
<pq>
kchibisov, btw. about Rust glutin and winit; can you say anything about winit maybe exposing the equivalent of a wl_surface.frame callback event?
<pq>
on Wayland it would be exactly the frame callback, and on other platforms if winit cares it might be anything roughly corresponding or even a timer if there is really nothing else.
<vyivel>
pq: the confusion might stem from xdg-shell.xml saying "A client is not required to commit immediately after sending an ack_configure request"
<pq>
emersion, swick[m], TIL that wxEDID is a GUI EDID editor, but apparently it has no public code repository, just release archives. Available as flatpak it seems.

I have the whole thing already working, except for the egl abstraction part

<daniels>
the intermediate shim is required to make sizes work
<daniels>
in X11, you create a Window with an innate size and then just point EGL at that - it can query to see what the size is and adjust
Guest5048 has quit [Remote host closed the connection]
<daniels>
since surfaces don't have an innate size in Wayland, the wayland-egl lib is just there to create a tiny wrapper which holds current & user-requested size
<pq>
swick[m], when you load a display profile from an ICC file, and then a client asks for that profile, do you: a) give the original file contents as-is, or b) since you parsed it with LittleCMS, let LittleCMS re-serialize it?

I'm not sure if LittleCMS would produce a byte-identical copy, especially if the ICC file had tags it doesn't parse. OTOH, if LittleCMS does not parse something, then the compositor won't understand it either.

why do we have a "Spam" label in wayland-protocols?
<emersion>
it seems unused
<pq>
emersion, it's the damspam mechanism, right?
<emersion>
damspam?
<pq>
slap it on an issue, and the author gets immediately blocked
<emersion>
i see
<pq>
rather than the "report spam" button which waits for some human to come around and look, while the spammer creates more spam
<pq>
actually more than blocked: it hides every issue the author had created, not just the labeled one

I'm working on godot, a FOSS game engine with a pretty complex windowing API and I'm attempting to change its API in a way that allows wayland to work with it
<riteo>
The reason I'm here is: is popup grabbing supposed to be used everywhere? It requires input serials and I can't seem to make it work for some reason
<riteo>
currently every other platform sends keyboard input to it manually, even when it looks like it grabs I can't dismiss the popup by clicking outside its geometry and it goes away when I focus out of the parent anyways
<riteo>
am I missing something?
<jadahl>
riteo: you should use grabbing popup if you want your popups to be automatically dismissed when e.g. the user clicks outside any of your windows, the lock screen appears and things like that
<riteo>
currently when I focus out it closes itself. That might be something that godot does
<jadahl>
there are some implementation details about pointer and keyboard focus, but in the end you can route however you want within your client
<jadahl>
running your client with WAYLAND_DEBUG=1 then looking at what requests to xdg_popup is done or what events are emitted can answer why your popup closes
<riteo>
yeah all right, mistery solved
<jadahl>
as in answer whether it's dismissed by the compositor, or the client itself
<riteo>
popups close themselves when focused out in godot
<riteo>
it's a godot thing
<jadahl>
\o/
<riteo>
like, when they receive a global focus out event they close themselves
<riteo>
should I still grab?
<jadahl>
if you want them to be auto-dismissed yes. e.g. if you click outsid, but it's on the desktop background, you wouldn't loose keyboard focus
<jadahl>
or wouldn't, you can't rely on loosing keyboard focus
<riteo>
it currently listens for a "global" application focus out event though
<jadahl>
(I'm assuming "global focus out" is keyboard focus or "activated" xdg-toplevel state)
<riteo>
oh I think it's actually pointer focus
<riteo>
yeah I'm not sure what would be the most reliable way
<riteo>
definitely not activated AFAIK
<jadahl>
pointer focus you loose as soon as the pointer leaves your window
<riteo>
that explains the weird behaviour
<riteo>
so I should rely on the keyboard focus, right?
<riteo>
sorry for all of the questions
<jadahl>
depends on what you're after
<riteo>
I'm not sure really. I'm trying to adapt an already existing, heavily Windows-like API which has only the concept of "focus"
<riteo>
yeah thinking about it keyboard focus would be better
<jadahl>
is it used for traditional File menus and such things?
<jadahl>
if so you can probably make it a grabbing popup and call it a day
<riteo>
do you mean the popups? Yeah, the ones that should auto-close are indeed dropdowns
<jadahl>
except you should hide when clicking outside the popup
<riteo>
all right, now I get the reasoning
<riteo>
thanks a lot for the help!
<jadahl>
so: makem them grabbing popup. destroy them when anything outside them gets clicked (or touched). destroy them on e.g Esc.
<jadahl>
destroying on keyboard focus lost I suspect is redudant, they'll probably be dismissed by the compositor before that
<riteo>
the weird thing is that destroying when clicked outside is platform-side, while focus out closing is engine-side
<jadahl>
riteo: fyi, when you create nested menus, the order of destruction is important
<jadahl>
riteo: doesn't hurt if you close on keyboard focus lost too I guess, if that's what you want
<riteo>
luckily there's some ordering so it shouldn't be an issue
<jadahl>
riteo: that is, keyboard of all your windows/popups, because a grabbing popup gets keybord focus when popped up
<riteo>
uh right
<riteo>
I think that the reasoning behind a global focus out is when no window is left focused that is godot's
<riteo>
so... I think I should be set?
<jadahl>
sounds like it, assuming popups are encountered for among those windows
<riteo>
great, thanks for the help once again!
<jadahl>
though, I can't remember the exact order of focus changes when going from parent to popup etc
<jadahl>
so might want to double check
<riteo>
I'm still doing a PoC so there's plenty of room for errors
<jadahl>
sounds like fun!
<riteo>
(I have to change the API, that's why)
<kchibisov>
Could I assume that server will immidiatelly destroy the objects, so I want to wait all objects being destroyed I could wait with wl_display.sync()? Or is it not enough and server could destroy things later on?
<kchibisov>
I'm trying to understand how to wait for wl_surface/toplevel being destroyed, before I 'pause' the loop.

what do you mean by pause the loop?
bodiccea has quit [Ping timeout: 480 seconds]
<emersion>
a wl_display.sync will ensure that the server has seen the destroy requests

well, I'll go for now. Bye!

I know that by default, it is not possible for an application to specify window coordinates. but what about a setup with multiple framebuffers? can an application specify which particular framebuffer to use for its window?
<vyivel>
dv_: do yoh mean wl_outputs?

<paramount>
finally. I do not really bother much anymore what others say. But final off-topic link. https://people.ece.cornell.edu/land/courses/ece4760/RP2040/C_SDK_DMA_machine/DMA_machine_rp2040.html that is what i am integrating into lief with my own execution encoding called HWbird. This gets my laptops going and i write little bit es2 backends and code for this too. Some security fixes on my laptops and start my own lab too.
