Yep, Jesus idea seems right. PySide (an dPyQt4) I guess being C++ bindings, one has to be careful with pointers. This is quite misleading sometimes. Fortunatelemy, with times, one learns the safe design patterns, so it(s not much of a problem.
By the way, it's quite surprising to see a reference to a view widget (QLabel) in a model item. I don't say it leads to bug nor that it is plain wrong, but it's just not very MVC (model view ocntroller pattern) stF On Sun, 10 Aug 2014 00:26:30 +0200 Jesus <ea7...@ea7dfh.com> wrote: > Hi > > I'm not an expert programmer in python nor pyside by far, but I've made > a test using pyqt4 with your code and the error is the same. > > This is the kind of bug when an object loss its reference to itself > inside a class.
