When I enter the constructor, I have a specific ‘this’ pointer that has the provided ‘size’ argument placed into its ‘entity_size’ member. However, when Qt subsequently invokes the boundingRect() override function, it’s an entirely different ‘this’ instance whose ‘entity_size’ has clearly not been initialized.I’ve looked at several select examples/widgets/graphicsview/ sources, and those show that this should be working as expected.I’ve tested this with 5.11.1 and 5.12.3 with the same result, so I’m guessing this is some kind of pilot error on my part.
Did you already run this code into valgrind / ASAN? HTH, -- Giuseppe D'Angelo | giuseppe.dang...@kdab.com | Senior Software Engineer KDAB (France) S.A.S., a KDAB Group company Tel. France +33 (0)4 90 84 08 53, http://www.kdab.com KDAB - The Qt, C++ and OpenGL Experts
