Hi,
since QString, QList, etc. are using qsizetype for indexing- and
size-operations.
What is the plan with classes working with aforementioned container
classes which are still using int in their interfaces?
If they keep using int there could be a lot of warnings like this one:
warning: implicit conversion loses integer precision: 'qsizetype' (aka
'long long') to 'int' [-Wshorten-64-to-32]
Or you have to plaster your code with casts. E.g. every time you pass an
index of your container to your model class.
Some classes which are probably affected:
QtCore:
* QAbstractItemModel and subclasses (using QList or std::vector as data
storage)
* QModelIndex
* QRegularExpression (match offset)
* QStringMatcher
* QSyntaxHighlighter
* QTextBoundaryFinder
* QXmlString::size
QtGui:
* QTextCursor
* QTextDocument (find offset, character{At,Count})
* QTextLayout
* QValidator and subclasses (validate offset)
QtWidgets:
* QAbstractItemView and subclasses
* QLineEdit
Kind regards,
Marcel
