WIP: FEAT(client): Add support to XDG Desktop Portal GlobalShortcuts #5976

aleixpol · 2022-11-25T18:57:35Z

This makes it possible to have global shortcuts on systems running the XDG Desktop Portal service. This is especially relevant on Wayland where we are not able to run a system-wide keylogger to get the global shortcuts triggers.

Fixes #5257

My commits follow the commit guidelines

WIP because I'm not very familiar because this is a codebase alien to me and I'm aware it's doing some nasty things. Still, I'd prefer to know how the maintainers want to do it rather than imagining myself what they want instead.

Note the GlobalShortcuts portal is merged to master but it still isn't released.

Why is the implementation using the name "xdp" rather than "xdg"?

And I'm wondering: Given that this is such a new feature, do we want to keep the old wayland notice in-place and show, if on wayland and if the new impl is not available?

+	target_sources(mumble_client_object_lib PRIVATE ${mumble_xdp_SRCS})


I feel like this should be outsourced into a dedicated cmake function implemented in a file inside the cmake directory. Then this place here could simply call that function.

Plus, it seems that we currently don't handle the case when the searched for file can't be found.

I moved both files to auxiliary_files.

I am not sure what you mean by adding the function. Do you still want it if we are not looking it up?

And out of curiosity: Will this be a flatpak-specific thing or will this (likely) solve the issue for Wayland users in general (also for non-flatpak apps)?

Yes, this should solve it for every Wayland system. Also it can work on X11 provided it's properly implemented in the backend like we are doing in KDE/Plasma and I expect others will too.

Sorry for the long delay since my last review - I have been rather busy

-#ifdef Q_OS_LINUX
-	if (EnvUtils::waylandIsUsed()) {
-		// Due to the issues we're currently having on Wayland, we disable shortcuts by default
-		bShortcutEnable = false;
-	}
-#endif


This should probably get the same treatment as the note in the settings UI

+        return {};


Just marking this so we don't lose track of this TODO

So to address this TODO we'll need to use an interface like this:
https://invent.kde.org/libraries/xdg-portal-test-kde/-/merge_requests/18

This means depending on Qt::GuiPrivate and libwaylandclient. If you are interested in this I can include it in this PR.

Hm. This seems rather hacky. What are the implications of simply leaving the implementation as it is? Aka: what exactly is the parent window ID being used for?
Will this perhaps only become relevant when dealing with multiple Mumble instances?

The parent window is simply to inform the portal who is calling this and which window the dialog should be on top.

The dialog will appear on top and focussed anyway, so it shouldn't be a big deal. FWIW, there will be public API for this in Qt 6 (6.5, if I'm not mistaken). If you don't want to depend on private API, just delaying until Qt 6 is a good option.

Okay in that case it indeed seems a good idea to simply delay this 👍

This makes it possible to have global shortcuts on systems running the XDG Desktop Portal service. This is especially relevant on Wayland where we are not able to run a system-wide keylogger to get the global shortcuts triggers. Fixes mumble-voip#5257

Two awkward things I've noticed which may or may not be related to the implementation in this PR:

you can't bind mouse buttons to global shortcuts. I assume this is either a deficiency specifically with this PR or with KDE's GlobalShortcuts interface ignoring all mouse presses
pressing a modifier while pressing a key does not allow for that key to be picked up by the shortcut, so if I bind F13 (or as KDE calls it, "Tools") to push-to-talk, I also need to bind shift+Tools, shift+ctrl+Tools, ctrl+Tools, alt+tools, ... which may be a deficiency in the entire protocol.

you can't bind mouse buttons to global shortcuts.

Correct, we don't have global shortcuts triggered my mouse in Plasma. It should be supported by Plasma or the Desktop Environment of choice of the user anyway.

pressing a modifier while pressing a key does not allow for that key to be picked up by the shortcut,

Again, this is Plasma deciding that they are not the same shortcut and not triggering it. There's not much we can (or should) do from this side. I suggest we continue this discussion in the bug report you created: https://bugs.kde.org/show_bug.cgi?id=465867

I suggest explaining a bit more on the bug report why it's important for anymodifier to trigger the subject's shortcut. If we have clear use cases it will be easier to get it acted on.

What's the status of this PR? Can't wait to enjoy global shortcuts in Mumble using KDE Wayland.
