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.
The "official" documented way is to include <QApplication> but <QtGui/QApplication> works as well.
how about I use "/usr/include/QtGui/QApplication.h"
?
JUST KIDDING

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