     5 Meta-Object System
       
     6 ------------------
       
     7 
       
     8 Qt 4.0.0 introduced a change to the way type names outside the current
       
     9 scope were handled in signals and slots declarations and connections
       
    10 which differed from the behavior in Qt 3.x.
       
    11 
       
    12 Unfortunately, this could lead to signal-slot connections that were
       
    13 potentially type-unsafe. Therefore, in Qt 4.0.1 type names must be fully
       
    14 qualified in signal-slot declarations and connections.
       
    15 
       
    16 For example, in Qt 4.0.0, it was possible to write:
       
    17 
       
    18     connect(socket, SIGNAL(error(SocketError)), ...);
       
    19 
       
    20 In Qt 4.0.1, the above connection must be made in the following way:
       
    21 
       
    22     connect(socket, SIGNAL(error(QAbstractSocket::SocketError)), ...);
       
    23

    25 Library
       
    26 -------
       
    27 
       
    28 Support for SGI Altix has been added for both gcc and Intel icc.
       
    29 
       
    30 
       
    31 QX11EmbedContainer and QX11EmbedWidget are now exported classes.
       
    32 
       
    33 This change only affects developers using Qt/X11 with gcc >= 4.0 and
       
    34 symbol visibility enabled. Applications built against Qt 4.0.1 that
       
    35 use these classes cannot be linked against Qt 4.0.0.
