Does someone know which GUI > libraries have been used for developing tool like DFII or VCAR? > > Camelot DFII prior to 6.1 used Motif toolkit (not sure which implementation, see http://www.opengroup.org/motif and http://www.openmotif.org/), and from 6.1 on switched to Qt (http://trolltech.com/products/qt ; Cadence is cited on their webpage). Other popular toolkits include GTK+ (http://www.gtk.org) and WxWidgets (http://wxwidgets.org). Stéphane
