Audacious - OLD, PLEASE USE GITHUB DISCUSSIONS/ISSUES

So what do you expect Audacious developers to do? It's not like there's a magical gtk_status_icon_show_in_lxqt() function we can call to fix this.

Hi John,

I am not sure if the cause is in Audacious or in the environment. But I do know, that my sticky notes application Xpad, uses the GtkStatusIcon too and it does show up. There is no magic lxqt code involved. :)

Maybe it has something to do with the way the icon theme is set in Audacious?
Here is a piece of 'tray-code' extracted from Xpad, maybe that helps?

static GtkStatusIcon  *docklet = NULL;
static GtkWidget *menu = NULL;

void
xpad_tray_open ()
{
    GtkIconTheme *theme;

    theme = gtk_icon_theme_get_default ();

    if (!gtk_icon_theme_has_icon (theme, PACKAGE)) {
        return;
    }

    if (gtk_icon_theme_has_icon (theme, "xpad-panel"))
    {
        docklet = gtk_status_icon_new_from_icon_name ("xpad-panel");
    }
    else
    {
        docklet = gtk_status_icon_new_from_icon_name (PACKAGE);
    }

    if (docklet)
    {
        g_signal_connect (docklet, "activate", G_CALLBACK (xpad_tray_activate_cb), NULL);
        g_signal_connect (docklet, "popup-menu", G_CALLBACK (xpad_tray_popup_menu_cb), NULL);
    }
}

Does this give you some inspiration for analyzing this issue?

Cheers,
Arthur.

Hi John,

I have an interesting discovery to share.

The Xpad version where the status icon works, is version 4.2. I have developed and released this version. It is based on GTK2.

Now, I had a hunch that GTK3 might be part of the cause of this. I looked up the GTK version of Audacious and it is GTK3. Let's not go into my annoyances of GTK, so ... <forget, darned, forget> :)

I compiled a GTK3 version which I was developing of Xpad, v4.3. And of course you can guess it by now: the status icon has exactly the same behavior as Audacious.

If I have more new information regarding this topic, I will share it.
If something comes up on your mind, please feel free to share.
That can help.

Cheers,
Arthur.

Maybe the GTK3 version is using a newer/incompatible protocol that a Qt-based tray implementation does not like? That's my guess, given that it seems to be the combination of GTK3 and Qt that is the problem.

Confirmed for Debian/Jessie with GTK+ (3.10.7-1) and Audacious (3.4.3-1).

What is confirmed?

The bug of course.

Sorry, but I am still trying to figure out what "the bug" is. If you know more about it than I do, then please write a patch to fix it. Otherwise, give some details about what you are "confirming". Are you also running LXQT? Or do you use KDE on an NVidia graphics card with the nouveau driver, as in #121? Or something else entirely?

Hi John,

... given that it seems to be the combination of GTK3 and Qt that is the problem.

This is my current assumption too.
Do you feel like investigating this issue together?

If no, I will switch audio player and we can close this bug report.
If yes (what I prefer), do you have some suggestions how to approach this?

I would suggest contacting the LXQT developers about the problem first, to see if they are aware of it or can give any additional clues. Also compare the GTK2 and GTK3 status icon code looking for any difference that might cause such a problem. If you have time, you could also install KDE to check whether your GTK-vs.-Qt hunch has any merit.

Okay, that sounds like a plan.
I will go work on it.

This might take some time, though.

Cheers,
Arthur.

Step 1.

Contacting lxqt developers --> done and awaiting answer.
https://github.com/lxde/lxqt-panel/issues/23

Step 2.

Comparing GTK2 and GTK3 statusIcon source code.

I have looked at it, but this one is a bit over my head. I have not enough knowledge of GTK to be able to find a possible cause. Would you mind and look through the code to see if you can find any clues? To make it easier, here are the two different sources.

https://git.gnome.org/browse/gtk+/tree/gtk/gtkstatusicon.c?h=gtk-2-24
https://git.gnome.org/browse/gtk+/tree/gtk/gtkstatusicon.c?h=gtk-3-10

In the mean time, I will go ahead and install KDE on one of my Linux distro's to see if I can replicate the same behavior of Audacious 3.5 and Xpad v4.3 (GTK3).

I don't see any changes in gtkstatusicon.c that should cause a problem. There could still be some subtle difference in a base class (such as GtkWidget) that is causing trouble for LXQT.

Step 3.

Testing in KDE

I have installed on an existing Lubuntu environment (LXDE), the package kubuntu-desktop (KDE). I have logged into KDE and started Audacious with the status icon plugin enabled. The icon was visible, concluding to me that Qt is not the issue. Maybe it is a mix of things, or something currently out of our scope.

What do you suggest next?

Agreed. Thanks John.

Hi John,

As we started to suspect, the issue was in LXQT.
Yesterday a patch has been released, which resolved this issue.

You can close this bug report.
