Bug 470583

This is working for me. I suspect a Neon packaging issue. Can you kill DiscoverNotifier, run it in a terminal window, and then print the output when you click on its System Tray icon?

I see these messages after running the notifier:

$ /usr/lib/x86_64-linux-gnu/libexec/DiscoverNotifier
qt.dbus.integration: Could not connect "org.freedesktop.NetworkManager" to "stateChanged"
qt.dbus.integration: Could not connect "org.freedesktop.NetworkManager" to "connectivityChanged"
qt.dbus.integration: Could not connect "org.freedesktop.NetworkManager" to "deviceTypeChanged"
qt.dbus.integration: Could not connect "org.freedesktop.NetworkManager" to "meteredChanged"

Nothing else appears after click on its system tray icon.

Interesting. Does Discover launch normally from e.g. Kickoff or KRunner?

yes

Ok, so Discover launches on its own, and the Notifier is interactive. There must be an issue with the way the Notifier is launching Discover for you. When clicked, it's running `plasma-discover --mode update`. Can you try that in a Terminal window?

Also, if you right-click on the Discover Notifier icon, do any of the menu items in its context menu do anything?

Nothing happens after right-click in the system tray icon.
Your command opens Discover with "Update" page focused.

Okay, next question: does `kioclient exec file:/usr/share/applications/org.kde.discover.desktop` do anything?

Discover opens with Home focused.

All right, thanks.

Well, I'm stumped. These exact lines of code in DiscoverNotifier.cpp are what's failing for Patrick (Neon Unstable), but they work for me (Self-compiled Discover on Fedora 38):


    auto *job = new KIO::CommandLauncherJob(QStringLiteral("plasma-discover"), {QStringLiteral("--mode"), QStringLiteral("update")});
    job->setUiDelegate(new KNotificationJobUiDelegate(KJobUiDelegate::AutoErrorHandlingEnabled));
    job->setDesktopName(QStringLiteral("org.kde.discover"));
    job->setStartupId(xdgActivationToken.toUtf8());
    job->start();

    auto *job = new KIO::ApplicationLauncherJob(KService::serviceByDesktopName(QStringLiteral("org.kde.discover")));
    job->setStartupId(xdgActivationToken.toUtf8());
    job->setUiDelegate(new KNotificationJobUiDelegate(KJobUiDelegate::AutoErrorHandlingEnabled));
    job->start();


Any ideas how to proceed here, Nico?

This bug affects the systray icon of any app. Nothing happens after left/right/middle click on the systray icon of Discord, OBS Studio and Strawberry player, for example.

*** Bug 471876 has been marked as a duplicate of this bug. ***

Is it working now, or still broken for all apps' tray icons?

It's still broken for all apps' tray icons.

Then let's track it in Bug 472003, because there's no indication here that Discover in particular is doing anything wrong. I don't see any defects in the code that could explain this.

Those warnings are harmless. I just fixed them in https://codereview.qt-project.org/c/qt/qtbase/+/527739 though.
