New coding policy standards which should be use in Calligra master

  1. Use Q_SLOTS ans Q_SIGNALS instead of slots/signals keywords we used before
  2. Add Q_DECL_HIDDEN to all nested Private classes in new code. A::Private need their symbols hidden, APrivate class does not, as it does not inherit the visibility from A.
  3. instead of #include <QDebug> and #include <kdebug.h> use #include <kis_debug.h>
  4. Use QUrl instead of KUrl and keep in mind that QString s; QUrl u = s; becomes QUrl u = QUrl::fromUserInput(s) or QUrl::fromLocalFile(s);
  5. KisIconUtils::loadIcon() should be used instead of previously used themedIcon()
  6. KAction is deprecated. Use QAction instead.
  7. Use C++11 instead of boost::function and boost::bind See Krita/C++11
