How can I obtain the current system icon theme in a Qt application? I tried QIcon::themeName, but it just returns an empty string. (But QIcon::fallbackThemeName works?!) Is there some "special trick" to using this method I am missing, or some other way to obtain the current theme name?
Possibly related to this, but none of the answers there seem viable. (Edit: Okay, one of the methods there does work... after I fix the OP's typos . However, I'd prefer not relying on a Gnome-specific technique or needing to execute an external process.)
