      Description

      https://doc.qt.io/qt-5/qtabwidget.html#indexOf
      Should take a const QWidget* or const QWidget& to allow this method to be used from const methods

       

      Consider this example:

      class Edit : QPlainTextEdit
      {
      Q_OBJECT
      public:
         Edit(const QTabWidget& parent) : _parent{parent} {}
         // would like to do: 
         // int myIndex() const { return _parent.indexOf(this)};
      
         // have to do:
         int myIndex() const { return _parent.indexOf(const_cast<Edit*>(this));};
      
      private:
         const QTabWidget& _parent;
      };
