Other How to change GTK / Qt themes in icewm


I've been using icewm as my window manager of choice for a while now but I can't figure out how to change themes for Gtk2-3 and Qt5. I've tried to use x11-themes/lxappearance and x11-themes/Kvantum respectively but neither one seem to make any changes to their dedicated applications. Can anyone shed some light on this? Thanks
You can change the appearance of GTK/Qt-based application by tweaking config files in ~/.config. For example, GTK3 themes can be set in ~/.config/gtk-3.0/settings.ini. Mine looks as follows:
gtk-print-preview-command=xpdf %f
While this does not configure a completely new theme, it fixes missing mouse cursor icons (that's currently all I want).
