    Default <QtGui/QApplication> vs. <QApplication>

    Whenever Qt designer 4.1 creates ui code the includes are generated as #include <QtGui/QApplication>, however documentation suggests to use #include <QApplication> instead.

    What are the advantages/disadvantages of both variants, and which should be used to stay compliant with future versions?

    It's completely the same. It's better to use <QApplication> as it is not vulnerable to a situation when directory structure of includes changes, but you may use both now.

    I have an argument pro <QtGui/QApplication>: On Macintosh-plattform, it is common to include headers in the way <framework/headerfile>. e.g. <OpenGL/gl.h>. <QtGui/QApplication> does also match that pattern. This is only important if you use Qt as frameworks on macintosh. The other way works fine when using a regular static or shared library.
    It's nice to be important but it's more important to be nice.

    The "official" documented way is to include <QApplication> but <QtGui/QApplication> works as well.

    hey, this doesn't work!!!!! qt header file names are lower-case, use "/usr/include/QtGui/qapplication.h" instead!!
    and dont forget:

    #ifdef WIN32
    #include "c:\my documents and settings\my text files\my include files\..\troll's include files\my qt\my qt 4\my qt 4.1\the include filesi'm looking for\QStupidApplication.h"
