Hands on I’ve been fascinated by cross-platform programming for more years than I care to remember, and my interest has recently been sharpened by the acquisition of a number of Apple Macs – both Intel and PPC (PowerPC). This article focuses primarily on some technical aspects of Qt, Trolltech’s cross-platform C++ toolkit which, as you may know, is the architectural core behind the KDE desktop on Linux.
