I want to run separate applications with different themes, the only solution for this that I could find was to use bash -c 'GTK2_RC_FILES=/path/to/gtkrc program'; however, I currently am using a XFCE4 theme which doesn't contain gtkrc file but a themerc file (i.e. it's an xfwm theme).
My question is - is there a environment variable I could modify to select window manager themes on per-application basis (analogous to GTK2_RC_FILES)?
