I have a DnDcontainer in Screen3 below. Drag and Drop into the DnDcontainer used to work fine, until I updated the project to use QStateMachine and QAbstractTransition, to add simple transitions between screens. After adding the transitions, everything works except Drag and Drop to the DnDcontainer, the DnDcontainer::dragEnterEvent and DnDcontainer::dropEvent methods are never executed, and when hovering over the DnDcontainer, I get a circle with a slash through it. What am I missing here? How do I pass the Drag and Drop signal to the DnDcontainer?
