QWidget::insertAction: Attempt to insert null action?

lansing

My project has a lot of QAction, I had declared them in the header and in the source, I gave them default to nullptr and instantiated them all at once with a loop. After that I assigned them to the different menus. However at the end, I have missed a couple of QActions somewhere and Qt Creator is giving me a warning

QWidget::insertAction: Attempt to insert null action?

How do I find out which one are they?

If it is a warning, you can set environment variable QT_FATAL_WARNINGS and app will crash whenever that message is printed. Then it should be trivial to check which action it is using an attached debugger.

QT_FATAL_WARNINGS

Thank you it works. Setting this and the debugger points me right to the spot that causes the warning.
