This class calls Qt::beginPropertyUpdateGroup() in its constructor and Qt::endPropertyUpdateGroup() in its destructor, making sure the latter function is reliably called even in the presence of early returns or thrown exceptions.
Note: Qt::endPropertyUpdateGroup() may re-throw exceptions thrown by binding evaluations. This means your application may crash (std::terminate()
called) if another exception is causing QScopedPropertyUpdateGroup's destructor to be called during stack unwinding. If you expect exceptions from binding evaluations, use manual Qt::endPropertyUpdateGroup() calls and try
/catch
blocks.
