\title Porting C++ Applications to Qt 5
\brief Provides instructions to migrate a Qt 4 C++ application to Qt 5.
This topic talks about the Qt Widgets change and provides guidance to handle it.
The following step-by-step instructions takes you through the changes required
to port the \l{Animated Tiles Example}{Animated Tiles} C++ application to Qt 5:
\list 1
\li Edit \c {main.cpp} and change the \c {#include <QtGui>} to \c {#include <QtWidgets>}.
\note You can find a perl script called fixqt4headers in the bin directory of your Qt package that will
automate many of the required header file changes.
\li Edit the \c {animatedtiles.pro} and add \c {QT += widgets} towards the end of the file.
\note QtGui is included by default in all Qt applications unless excluded using the \c {QT -= gui} directive in the \c{qmake} project file.
\li Run qmake and make utilities to build the binary.
\endlist
This creates the \c animatedtiles executable. Try running the executable to see if the application behaves as expected.

A similar change is needed for porting Qt 4 applications using Qt WebKit to Qt 5. The following
step-by-step instructions take you through the changes required to achieve this:
\list 1
\li If using \c {#include <QtWebKit>}, add \c {#include <QtWebKitWidgets} in your source code.
\li Edit the pro file and add \c {QT += webkitwidgets} towards the end of the file.
\li Run qmake and make utilities to build the binary.
\endlist
