[PyQt] Strange observation
Hello, there was a strange observation reported using eric5. The eric5 PySvn plug-in has a dialog to ask the user for a password. This is embedded in code like this cursor = QApplication.overrideCursor() if cursor is not None: QApplication.restoreOverrideCursor() call the login dialog, could take some time depending upon the user if cursor is not None: QApplication.setOverrideCursor(cursor) Every now and than this code fails with class 'RuntimeError': wrapped C/C++ object of type QCursor has been deleted What is wrong with my code?

Probably... overrideCursor() returns a pointer to an internal copy of the cursor. This is deleted by restoreOverrideCursor(). Before calling restoreOverrideCursor() make a copy... cursor = QCursor(cursor) Phil ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Strange observation with Qt5/PyQt4
Hello, testing eric5 with Qt5 and latest PyQt4 snapshot raised a strange observation. The eric5 Web Browser shows dialog windows generated by Qt5 with content like Trying to construct an instance of an invalid type, type id: 627995709 Does anybody have an idea what could causing this?

The fix is for QListWidgetItem, QTableWidgetItem and QTreeWidgetItem. If there are still issues with other classes (eg. QModelIndex) then it's a different problem. Phil ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt The fix seems to work. Thanks Phil.
