What I mean is that a Qt app will look native everywhere, and Gtk apps will look native in most places.<p>Most other toolkits, as you mentioned, don’t look native in many places, but Qt natively supports the CDE style, the Motif style, all different Windows and Mac styles, etc.<p>A Qt app looks native on Mac OSX, on Solaris, under Gnome, under KDE, under Windows XP, under Windows 10.<p>That’s why I avoid apps that aren’t either native or Qt anywhere, no matter if I am running Gnome or Windows, KDE or Mac.
