The system header class has virtual bool edit(const QModelIndex &index, EditTrigger trigger, QEvent *event); my class has bool edit(const QModelIndex &index, int editDay); when compiling with -I to add include paths i get In file included from /usr/include/qt/QtWidgets/qtreeview.h:44, from /usr/include/qt/QtWidgets/QTreeView:1, from /home/tsdgeos/kdab/private/KDABViewer/Widgets/TimelineWidget.h:4, from /home/tsdgeos/kdab/private/KDABViewer/Widgets/TimelineWidget.cpp:1: /usr/include/qt/QtWidgets/qabstractitemview.h:297:18: warning: =E2=80=98vir= tual bool QAbstractItemView::edit(const QModelIndex&, QAbstractItemView::EditTrigger, QEvent*)=E2=80=99 was hidden [-Woverloaded-virtual] 297 | virtual bool edit(const QModelIndex &index, EditTrigger trigger, QEvent *event); | ^~~~ In file included from /home/tsdgeos/kdab/private/KDABViewer/Widgets/TimelineWidget.cpp:1: /home/tsdgeos/kdab/private/KDABViewer/Widgets/TimelineWidget.h:66:10: note:= =20=20 by =E2=80=98bool TimelineWidget::edit(const QModelIndex&, int)=E2=80=99 66 | bool edit(const QModelIndex &index, int editDay); | ^~~~ but if instead of -I i use -isystem the warning is gone. This feels wrong since the warning is about my code, not about the system include code.=
