Function currentIconThemeName

Try to detect the current icon name configured by user.

string currentIconThemeName (
  IconThemeNameDetector detector = cast(IconThemeNameDetector)15
) nothrow @safe;

This function is Freedesktop only.

Note

There's no any specification on that so some heuristics are applied. Another note: It does not check if the icon theme with the detected name really exists on the file system.
