I've really like using OctoXbps in KLV-KDE-plasma, as it's notifier works in the taskbar, and OctoXbps also uses the available gtk plasma theme. Of course KLV-plasma runs as spot user.
So I was checking out Spectr, mine based off RC1, but thoroughly up to date, and heavily customized by this time. In fact in early August I did a resquash from a long running PFI.
At any rate, in Spectr, OctoXbps runs as spot, so I copied a gtk theme, beauty-solar icons, and gtk2.0.rc along with the ./config/gtk-2 and /gtk-3 directories containing the settings .ini into /home/spot. In other words everything that seems to need being present for the themes to load.
And in fact they do, if I run Geany as spot from a terminal, it uses the gtk Chrome Oceanic theme and the Beauty Solar icons. But OctoXbps doesn't.
I poked around all the OctoXbps configs I could find, and nothing seems to reference what theme to use.
So is possible in Spectr?, or is that simply Plasma making the theme aspect of OctoXbps go?
