Therefore, in Qt 4.0.1 type names must be fully +qualified in signal-slot declarations and connections. + +For example, in Qt 4.0.0, it was possible to write: + + connect(socket, SIGNAL(error(SocketError)), ...); + +In Qt 4.0.1, the above connection must be made in the following way: + + connect(socket, SIGNAL(error(QAbstractSocket::SocketError)), ...); + + +Library +------- + +Support for SGI Altix has been added for both gcc and Intel icc. + + +QX11EmbedContainer and QX11EmbedWidget are now exported classes. + +This change only affects developers using Qt/X11 with gcc >= 4.0 and +symbol visibility enabled. Applications built against Qt 4.0.1 that +use these classes cannot be linked against Qt 4.0.0. + + +**************************************************************************** +* Changes *
