feat: alt tab cycle #150

wiiznokes · 2024-07-03T01:57:47Z

impl #135.

Related to this pr pop-os/launcher#227. Need to be merged at the same time. (actually, the pr in pop-launcher need to be merged first)

wiiznokes · 2024-07-03T12:34:02Z

This could definitively be improved, by supporting shit+alt+tab, and selecting the 1 index when alt+tab is pressed, but this will require more changes. And since killing cosmic-launcher make cosmic-comp freezing, i think this can be merged as is for now.

Still need pop-os/launcher#225 to be merged first because cosmic-launcher depend on it.

src/app.rs

wiiznokes · 2024-07-11T15:12:45Z

@wash2 So i'm looking to resolve this part

todo:

handle the case where the search have not finished but the alt-tab command need to be processed

This is my idea,

wrapper around tx, to make a request: self.request(launcher::Request::Search(String::new());. This function will set a field waiting_result = true (if we don't care to wait, we could make 2 functions, e.i, for launcher::Request::ActivateContext(i, context)).

Then, we add our message to a queue: self.queue.push(Message::AltTab).

The result will set waiting_result = false, and process the messages in the queue.

The question is, will it interfere with wait_for_result: bool, ? wdyt ?

edit: i'm not sure waiting_result is useful in this case. Just the queue should do it

wash2 · 2024-07-11T15:19:06Z

Then, we add our message to a queue: self.queue.push(Message::AltTab).

Ya, I think a queue of unprocessed messages could work well 👍

Probably because of the force push in launcher. But this comment pop-os/launcher#227 (comment) still need to be addressed before merging this ig

jacobgkau · 2024-08-08T20:21:46Z

Ok. @Drakulix When you have time, let us know if you have any input regarding the compositor protocol side of pop-os/launcher#227.

Drakulix · 2024-08-09T11:54:48Z

Ok. @Drakulix When you have time, let us know if you have any input regarding the compositor protocol side of pop-os/launcher#227.

I am not sure where the additional events come from (probably this represents cosmic-comps internal focus stack), but the protocol as it stands doesn't guarantee any "order" of the advertised windows. Just that the state will be eventually consistent with the compositors state.

Just fyi, I wasn't using any stack at that moment. I will try to test further to see if it's specific to some applications. So, what would be the protocol to use in this case?

Drakulix · 2024-08-09T13:35:34Z

Just fyi, I wasn't using any stack at that moment.

"Focus stack" internal to cosmic-comp != stacking in cosmic-comp.

So, what would be the protocol to use in this case?

I don't think we have a protocol serving this case. What this needs is probably some protocol design to expose the necessary info.

wiiznokes · 2024-08-10T21:35:56Z

I asked KDE on matrix and they don't use a protocol for this. I will let you guys come up with a protocol because i don't think i'm experienced enough rn.

I think we have 2 options

returning an array of all windows sorted by last focus
return an event each time a windows is focused

If the option 2 is choosed, there is some usefull code is theses PRs

wiiznokes · 2024-08-26T13:13:20Z

@Drakulix Could the protocol cosmic-toplevel-info be changed to guarantee an order ? I'm asking that because if i would write one, i would probably change nothing except this. It can differentiate different instance of the same app (thought not sure if it can group them).

Since it is a protocol special to cosmic, i thought i would ask.

codegod100 · 2024-08-26T14:21:53Z

Thank you for your service

We added a global done event to cosmic-toplevel-info-v1 version 2.
A draft implementation of the compositor side of said protocol can be found here: pop-os/cosmic-comp#870

This should be enough to allow experimentation and figure out, if this solves the issues with this PR and allows to properly track focus.

wiiznokes · 2024-09-18T15:23:25Z

Ok, I will work on this soon

wiiznokes · 2024-09-18T19:03:28Z

I've updated both PRs. Running pop-os/cosmic-comp#870 broke the applist, and i don't receive any update here for some reason @Drakulix

Hmm, that definitely should have broken older clients, I'll have to check that.

But that branch itself won't fix things. You need to use v2 of the protocol and also the ext-foreign-toplevel-list protocol (as that is mandatory with v2). So cosmic-client-toolkit needs to be updated as well to follow these changes.

I don't understand how both protocol can be shared.

pub trait ToplevelInfoHandler: Sized {
    fn toplevel_info_state(&mut self) -> &mut ToplevelInfoState;

    fn new_toplevel(
        &mut self,
        conn: &Connection,
        qh: &QueueHandle<Self>,
        toplevel: &zcosmic_toplevel_handle_v1::ZcosmicToplevelHandleV1,
    );

    fn update_toplevel(
        &mut self,
        conn: &Connection,
        qh: &QueueHandle<Self>,
        toplevel: &zcosmic_toplevel_handle_v1::ZcosmicToplevelHandleV1,
    );

    fn toplevel_closed(
        &mut self,
        conn: &Connection,
        qh: &QueueHandle<Self>,
        toplevel: &zcosmic_toplevel_handle_v1::ZcosmicToplevelHandleV1,
    );
}

and

pub trait ForeignToplevelListHandler: Sized {
    fn foreign_toplevel_list_state(&mut self) -> &mut ForeignToplevelList;

    /// A new toplevel has been opened.
    fn new_toplevel(
        &mut self,
        conn: &Connection,
        qh: &QueueHandle<Self>,
        toplevel_handle: ext_foreign_toplevel_handle_v1::ExtForeignToplevelHandleV1,
    );

    /// An existing toplevel has changed.
    fn update_toplevel(
        &mut self,
        conn: &Connection,
        qh: &QueueHandle<Self>,
        toplevel_handle: ext_foreign_toplevel_handle_v1::ExtForeignToplevelHandleV1,
    );

    /// A toplevel has closed.
    fn toplevel_closed(
        &mut self,
        conn: &Connection,
        qh: &QueueHandle<Self>,
        toplevel_handle: ext_foreign_toplevel_handle_v1::ExtForeignToplevelHandleV1,
    );

    fn finished(&mut self, _conn: &Connection, _qh: &QueueHandle<Self>) {}
}

Do i really need to implement both ? I'm not sure how if yes

Drakulix · 2024-09-20T11:51:00Z

What you are looking at are the abstractions provided by sctk and cctk, of course they are incompatible. What was needed here was for the cctk abstraction to be updated to handle both protocols in the background and use version 2.

@ids1024 just added such an update: pop-os/cosmic-protocols#35
The cosmic-comp branch also has been updated with a few fixes.

ToplevelInfoHandler has now a new info_done-method, which should be used to diff the Activated states to track the last new focused update.

E.g. cosmic-comp might still send events that result in five update_toplevel calls, but those should only update the states, while on info_done the latest Activated-window should be considered the new "focused" window compared to the last info_done event. Makes sense?

wiiznokes · 2024-09-20T12:38:11Z

Ok, i've updated the launcher to use pop-os/cosmic-protocols#35, and also updated cosmic-comp. The applist is still broken, and pressing alt-tab make a black screen

Are you sure you updated the compositor? Because the app-list works fine for me with the latest commit (it definitely was broken before, just like the missing update-toplevel-events).

wiiznokes · 2024-09-20T19:31:24Z

Oops, probably not, i didn't know i had to update my fork branch

Ok, i think i understand. When info_done is called, it should only have 0 or 1 active state across all top level. However, info_done is never called in my tests

wiiznokes · 2024-09-22T21:12:25Z

Edit: i must have done something wrong, info_done is called as it should. I've updated pop-os/launcher#227 with the necessary changes

I'm assuming we won't want to merge this reference to a fork into master.

If pop-os/launcher#227 doesn't cause any regressions for the pop-shell frontend on 22.04, then I can regression test that one and we can get it merged first, if that would help? (It'd be nice to be able to test that it works properly, and I can also still do that if we get this PR to build.)

I will look into it. I must say I ran into this problem, but the problem it's just the target/target (should be one target), so it's easy to work around it.

If you want to test the other pr, you must also install this one for it to work

should be fixed. We probably want to merge
