\title Changes to Qt State Machine
\ingroup changes-qt-5-to-6
\brief Migrate Qt State Machine to Qt 6.
Qt 6 is a result of the conscious effort to make the framework more
efficient and easy to use.
We try to maintain binary and source compatibility for all the public
APIs in each release. But some changes were inevitable in an effort to
make Qt a better framework.
In this topic we summarize those changes in Qt State Machine module, and provide
guidance to handle them.
\section1 Changes
The Qt StateMachine module is generally speaking source compatible with the Qt5
version and users of the library should be able to continue with no or
minor changes to their project.
\section2 QSignalTransition
The \l [CPP] QSignalTransition::senderObject() getter and the related
Q_PROPERTY now also use const QObject*. These are now better aligned
with the setter \l [CPP] QSignalTransition::setSenderObject(const QObject*) that takes a
const QObject* as a parameter.
\section1 Build system
As with Qt 6 in general, the Qt State Machine module has cmake support in addition
to qmake.
\section1 QML imports
The QML import versioning is optional unless one has a specific
reason for not using the latest. Generally speaking the versioned imports
work from version 5.8 to 6.x, where 'x' is the current minor release.
