I know, (in Linux) exporting “SAL_USE_VCLPLUGIN=kde4” makes LO use the KDE theme, but I don’t have KDE installed, yet I’ve got an almost pure Qt-only system (with Fluxbox window manager).
I manage my system-wide Qt theme by a fine qt5 config utility called qt5ct and exporting “QT_QPA_PLATFORMTHEME=qt5ct” in ~/.bashrc. There are various qt(5) theme/vidget engines like the default fusion, qtcurve, kvantum and virtuality (my present one being qtcurve).
Can I make LO use Qt theme without installing KDE?
