So... after a full day of debugging, trying to port my Qt4 app to Qt5 and chase down a nasty case of stack clobbering, I discovered that the problem is that QMatrix4x4 changed from qreal to float.
(Uh...why? I am not particularly amused by the loss of precision, nor the extremely subtle incompatibility.) Alas, there does not seem to be any feasible replacement in Qt. I can't use QGenericMatrix because it can't be used to transform QPointF's, nor can it be inverted, both of which are features I require. I *really* don't want to throw out the precision of double, especially as I have tons of other code that still uses double and would have to wade through mountains of conversion warnings to do so. Am I missing something, or do I need to drag in Eigen? -- Matthew _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
