[Qt-interest] include modules vs. files

[Malyushytsky, Alex]

Such comprehensive includes as QtGui usually are provided for convenience.
I might consider to use it only, if include section does not fit a page in the editor, because I had to include a large number of the headers which are available at QtGui header. In this case including QtGui would improve readability of the code.

Including specific header is more informative than QtGui, and requires less compilation time unless you need all the includes anyway.

Best regards,

Subject: [Qt-interest] include modules vs. files

When looking at the help files for, say, QLineEdit, you see that it is
in a specific module (QtGui), as well as the specific header for the
module (QLineEdit). If you are only using a handful of object types in
your application, is there an advantage to #including just the
specific headers you need, rather than the entire module? Or would
that just be wasted effort with no benefit? I would imagine that the
executable size might be somewhat smaller, but I would like
confirmation (or refutation) of this. Thanks!
