Description Patrick Silva 2020-07-15 11:52:28 UTC
1. install Weather Widget or Redshift Control widgets from KDE Store
2. open system tray settings, click on "Entries" section: the just installed widget is not listed
3. restart Plasma by pressing alt+space and running "plasmashell --replace"
4. reopen system tray settings, "Entries" section: now the widget installed in the step 1 is listed

a widget from KDE Store should be listed in system tray settings immediately
after it to be installed

Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.19.80
KDE Frameworks Version: 5.73.0
Qt Version: 5.14.2
Comment 1 David Edmundson 2020-07-15 12:16:42 UTC
Potentially we can do something like


      QDBusConnection::sessionBus().connect(QString(), QStringLiteral("/KPackage/Plasma/Wallpaper"), QStringLiteral("org.kde.plasma.kpackage"), QStringLiteral("packageInstalled"),

(but with applets instead of wallpapers obviously)  to watch changes

It's that or just rebuild the model anew everytime the config is opened,

Watching for changes makes sense to me, but what do you think, Konrad?

Good idea, I didn't know there is such signal! :) IT should also listen on package uninstall, so that we can immediately remove applet (I think there is a separate bug for this).

It requires some refactoring in systemtray.cpp, not only in model - applet can be "DBus-able" (m_dbusActivatableTasks) or enabled by default (m_defaultPlasmoids).
