Minimize to tray on Plasma5 (KDE)

[ochurlaud]

Is there an option or a plugin to install to minimize to tray?

I'm using Plasma5 on Archlinux and when I quit QuodLibet, it quits for real...

Thx

Go to "Music", then "Plugins" and activate "Tray Icon", that should do it.

[ochurlaud]

Ok, the problem is that KDE doesn't show it in the tray bar...

[lazka]

Afaik plasma5 no longer supports tray icons. Might be related: #1343

[ochurlaud]

It does support, but it follows this spec: http://www.freedesktop.org/wiki/Specifications/StatusNotifierItem/ which is (as I understood) the right one...

[lazka]

We don't support that atm (I didn't know that that was used outside of Ubuntu where mpris + the unity task bar integration is usually enough..)

See https://lazka.github.io/pgi-docs/#AppIndicator3-0.1

[ochurlaud]

Is it what is used?

[lazka]

Is it what is used?

What are you referring to?

On Linux there are four things for exposing a menu of some sorts:

1. The old tray icon spec, which is X11 only, deprecated in most toolkits but still in use by things like Skype/VLC/dropbox etc. We do support that atm.
2. Ubuntu Unity provides an API for exposing a menu in the left taskbar. We support that atm.
3. Then there is MPRIS1/2 which some DEs use to build a mediaplayer widget (Ubuntu for example, or when using GNOME with an MPRIS extension). We do support that.
4. And then there is the spec you mentioned which we currently don't support, but I guess we should if KDE moved to it.

[ochurlaud]

Ok. I think KDE was using what you put in 1). But they movedto 4) and 3).

I was asking if your link (api) is what you currently use.

[lazka]

Possible. I remember that early Ubuntu versions only used MPRIS if (4) was implemented.. maybe that's the case here too

I was asking if your link (api) is what you currently use.

This is the Python API for implementing https://wiki.freedesktop.org/www/Specifications/StatusNotifierItem/ (If I'm not mistaken..)

[ochurlaud]

So it means that it's almost solved isn't it?

Note that Plasma 5.5, which came out today, has a new change related to this:

In response to feedback, we've rewritten support for legacy applications not using the StatusNotifier standard for system tray icons.

(From https://dot.kde.org/2015/12/08/plasma-55-beautiful-new-artwork)

[ochurlaud]

Yes I saw that too... Nevertheless they reimplement the 1) on lazka's list which is old and deprecated, so going to the new things (4) seems needed.

Thanks for the info.

Agreed, especially as (1) doesn't work with Wayland.

[lazka]

Basics are working now with master. But you need libappindicator-gtk3 (afaics this in only in AUR)

[ochurlaud]

I've got it. I'll check this. Thx a lot.

[lazka]

Things should work now in master, so I'm closing this. If there are any problems please report them here or in a new issue.

[ochurlaud]

@lazka: is this patched in 3.5.3? thx

[lazka]

No, but as pointed out in #1756 (comment) the old tray icon should work again if you update to plasma 5.5.

This will be part of 3.6

I guess we should look into providing an unstable build for the AUR..

[lazka]

See #1805

[ochurlaud]

I can write one if you want.... With the upgrade of plasma 5.5 it doesn't really work. You have an icon, but most of the time black, never scaled.

[ochurlaud]

From master branch:

• As you can see it's not perfect... http://postimg.org/image/56dhc05x5/
  Sometimes (not often) the icon is ok.
• Clicking on it never reopens quodlibet (or doesn't do anything at all).

@lazka I don't find the "Reopen" button.

[lazka]

What's your output for python2 -Wignore -c "from gi.repository import AppIndicator3"

[ochurlaud]

No output....

[lazka]

Weird.. Do you see the "Show Quod Libet" menu item on top of the menu?

Here is how it looks on an uptodate arch (plasma 5.5.4). I've installed quodlibet-git and libappindicator-gtk3 through yaourt

[ochurlaud]

Ok... I'm on plasma 5.5.4 as well, libappindicator-gtk3 as well but it's still the same : weird icon, no interaction with the icon (no menu either)....

Don't know why... I'll try to check if I'm missing something. Are you using the Tray Icon plugin?

Very strange.

[ochurlaud]

I just completely uninstall quodlibet and check the config of plasma.. Still the same.
Next try: in virtualbox.

[ochurlaud]

D: 249.60: fake.plugins.trayicon.get_indicator_impl: use app indicator: False

XDG_SESSION_DESKTOP is set with KDE. but you check plasma.
--- This might be the problem?
I asked on IRC, KDE is the expected value... Any idea?

[lazka]

hm, It's plasma here.. maybe because I use gdm3, I'll have a look

(That's why I asked about the "Show Quod Libet" item, which is only there if AppIndicator3 is used..)

[CreamyCookie]

Okay, AFAICS this was fixed in #1813. I've also just tested the Tray Icon plugin (Kubuntu 18.04) and it works flawlessly.
