Re: [PyQt] Regressions on destruction of objects?
FYI, with PyQt4 v4.6.1, the matplotlib's Qt4 backend is no longer usable interactively because the 'destroyed()' signal is not emitted when matplotlib's figure (QMainWindow instance) is closed (and destroyed, thanks to the Qt.WA_DeleteOnClose attribute). In other words, one can only show one figure with matplotlib/PyQt4 v4.6.1. Is there going to be a v4.6.2 release soon with this issue fixed? Thanks, Cheers, Pierre ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
