Hi all, In Debian, we have recently removed the gtk2 platform theme from default Qt 5 installation [1], and now I start getting reports about missing icons in my Qt 5 application on Debian (currently Qt 5 supports themed icons only on KDE and when using the gtk2 platform theme).
>From the discussion it seemed that we can keep the platform theme around, but only if it is ported from GTK+ 2 to GTK+ 3. That task itself is not hard, but then this theme will become incompatible with QGtkStyle, which is using theming engine specific to GTK+ 2, and GTK+ 3 port does not seem possible. Looking at QGtkStyle, it not only relies on a deprecated library, but doesn't play well with default GNOME theme (Adwaita). Also, the theme authors usually do not care about GTK+ 2 anymore, and focus their efforts on a CSS theme for GTK+ 3. Also, Adwaita theme is now available in a native Qt 5 variant [2], i.e. Fedora ships it. So my question is: can we drop the QGtkStyle completely and port the gtk platform theme to GTK+ 3? I will contribute to that effort if it gets the consensus. [1]: https://bugs.debian.org/781148 [2]: https://github.com/MartinBriza/adwaita-qt -- Dmitry Shachnev
