I've pushed the Qt4 interface to a branch. It is functionally equivalent to the Qt(3) interface, but uses PyQt4 instead of PyQt: http://www.algonet.se/~afb/smart/qt4.html It'll get merged as we update the old GTK 2.4 interface, with the new searchbar and so on... But GTK+ is backwards compatible, so that can all stay in the same "gtk" interface for smart. --anders
