Add support for qt5ct with qt5-gtk-platformtheme #1357

Open lwbt opened 5 years ago

lwbt commented 5 years ago

Expected Behavior

QT5 apps like KeepassXC and VLC should render in GTK3 Yaru style instead of Adwaita.

I did some research and found threads where qt5ct with qt5-gtk-platformtheme is recommended: https://github.com/keepassxreboot/keepassxc/issues/1931

Actual Behavior

Only Adwaita is offered in the selection.

Steps to Reproduce the Problem

  1. apt install qt5ct qt5-gtk-platformtheme
  2. run and configure qt5ct, for example to use a dark theme variant
  3. run example app with QT_QPA_PLATFORMTHEME="qt5ct" vlc or put it in your .profile file

Hi @lwbt, thank you for taking time to report this and for the research, awesome! I wonder how we can add yaru to the list, we might need to reach the maintainers of the project and ask them

Hi @lwbt -From your description it looks like you installed only Yaru-shell theme, correct me if I'm wrong. IF I'm right you have to install the Gtk part of it that include Gtk3+Gtk2 as well. When you do : Try to choose Gtk2 in the menu and run your example line like this : QT_QPA_PLATFORMTHEME="gtk2" vlc Is it working for you that way?

Yaru is installed by default in 19.04, no need to install other pieces manually

That's correct @clobrano , Sorry! I'm still on 18.04 LTS . But all the rest should work as far as I understand.

Opened the zip.. isn't this the same as https://github.com/ubuntu/yaru/issues/1294 ?

lwbt commented 5 years ago

I don't see any relation.

Feichtmeier commented 5 years ago

Nvm, I should stay away from GitHub before 10:00 xD

The Qt5 configuration tool will only show Qt themes. There is an Adwaita Qt theme, which provides Adwaita and Adwiata-Dark for Qt apps - which is why these appear in the list. For Yaru to appear in this list, there would need to be a pure Qt version of Yaru.

I seem to recall that Adwaita-Qt is GPL licenses, as is Kvantum, so not sure Ubuntu can install that - for the same reasons it cannot use Kvantum.
