Only workarounds.

They will enable GTK Theming again in QT 5.8, due november.

For LXDE users, please use lxsession-git package from AUR, then run qt5ct.

You should be able to run qt5ct without error after installing lxsession-git package

choose gtk2 and apply the setting. Enjoy your gtk2 experiance on QT 5.7

Re: [SOLVED] Qt 5.7: Widget style GTK is not longer available

Ok, I'm completely confused now.
I'm running xfce4 with i3 as windows manager. I've set the following vars:

QT_PLATFORMTHEME=qt5ct
QT_PLATFORM_PLUGIN=qt5ct
QT_QPA_PLATFORMTHEME=qt5ct

When I try to launch qt5ct:

$ qt5ct
qt5ct: using qt5ct plugin

(qt5ct:8617): GLib-GObject-WARNING **: 21:32:09.057: cannot register existing type 'GdkDisplayManager'

fish: “qt5ct” terminated by signal SIGSEGV (Address boundary error)

The thread is marked as solved but I can't find a suitable solution for me. Did I miss something? How can we solve this mess?

It has been 2 years a lot has changed in the meantime, if you want help open your own thread with more up to date details on your software stack and expectations.

Don't necrobump: https://wiki.archlinux.org/index.php/Co … bumping.22

Closing.
