Arch Linux User Repository

Looks like it's over, Plasma 5 is removed from the repos. Now the only things possible to do are to remove the package somehow (how? I don't see such a button) or to wait, maybe someone will re-package the deps in the AUR.

Some user guide:

My patchset contains multiple fixes/features in comparison to vanilla qt5ct:

1. KDE color schemes support
2. KDE QML applications theming support
3. KDE's icon engine is used, fixing monochrome icons colors (I saw problems with e.g. Adapta Kvantum theme on KDE applications toolbars, like dolphin, they're grey when should be white)

It's important to set a KDE color scheme (marked as (KColorScheme) in the list) for proper theming of KDE apps.

Additionally, if one wants KDE dialogs, this could be reached either with plasma-integration or xdg-desktop-portal (both work with vanilla qt5ct, too).

To get them with plasma-integration:

1. Install plasma-integration
2. Choose KDE as standard dialogs in qt5ct configurator

To get them with xdg-desktop-portal-kde:

1. Install xdg-desktop-portal + xdg-desktop-portal-kde
2. Configure xdg-desktop-portal's FileChooser to kde, see https://wiki.archlinux.org/title/XDG_Desktop_Portal#Configuration
3. Ensure that session dbus instance is running correctly
4. Choose XDG Desktop Portal as standard dialogs in qt5ct configurator

How to ensure that session dbus instance is running correctly when using xinit (DMs should already do the right thing for you):

1. Ensure you don't have dbus-launch nor dbus-session-run in .xinitrc
2. Ensure you copied the for f in /etc/X11/xinit/xinitrc.d/?*.sh loop from /etc/X11/xinit/xinitrc to your .xinitrc
3. Ensure you have no errors in systemctl --user status dbus and the service is running. You shouldn't enable the service, it should be activated by dbus.socket.

In case of Wayland, you may need to integrate your WM with systemd (that's what one of the scripts in /etc/X11/xinit/xinitrc.d does for X11): https://github.com/swaywm/sway/wiki#gtk-applications-take-20-seconds-to-start

No, sadly it's made without debug symbols, but it seem to look like a Qt bug.

I'm not sure if this backtrace helps: https://bugs.kde.org/show_bug.cgi?id=469168#c2 I also reported the bug to the audiotube dev to see if they can assist

qqc2-desktop-style uses Kirigami itself, so it can add additional Kirigami-related warnings likely. I can't help with crashes without backtraces though (obtaining which would likely involve rebuilding Qt, KDE libraries and applications themselves with debug symbols).

Yes, I did mean the Kirigami message. However, the messages don't appear when setting the two environment variables to Fusion when running Kirigami QtQuick applications. Moreover, some Kirigami applications segfaults directly (Kalendar & Audiotube from what I've tested) and cannot be launched.

What 'the error' is? The error string you previously posted refers to a bug in the KDE's Kirigami framework. I believe you can just ignore it as most errors from QtQuick applications.

Wait, the issue persists. I was trying the wrong thing.

When I execute when the theme is set to Fusion in qt5ct:

QT_QPA_PLATFORMTHEME=qt5ct QT_STYLE_OVERRIDE=qt5ct-style audiotube

the error exist.

However, when I execute the following:

QT_QPA_PLATFORMTHEME=Fustion QT_STYLE_OVERRIDE=Fusion audiotube

It executes normally

After some toggling, I noticed that it only occurs when using kvantum themes, so it's more related to kvantum. Sorry for any inconvenience.

Can you prove somehow that this is due to this package? The error doesn't sound related.

This package works like charm on some KDE QtQuick applications. However, most outputs file:///usr/lib/qt5/qml/org/kde/kirigami.2/styles/Plasma/Theme.qml:73: TypeError: Cannot read property 'Theme' of undefined and few even segfaults.

The single best package in the aur. Makes qt5ct actually work like it's supposed to
