[PyQt] pyqtSlot, getting undefined return values when called from qml javascript
I have a qml file invoking methods on a QObject subclass. I have used @pyqtSlot decorator to expose the methods as slots. I can see that the methods are run; however, the return values seem to be discarded. Code for the QObject subclass (that I expose with setContextProperty) is like this: === from PyQt4 import QtCore from PyQt4.QtCore import QObject,pyqtSlot class NodeWrapper(QObject): def __init__(self, c,v): QObject.__init__(self) self.c = c self.v = v @pyqtSlot() def get_b(self): return 2 #return self.v.b @pyqtSlot() def get_h(self): return self.v.h @pyqtSlot() def children(self): #self.all = all = [NodeWrapper(self.c, chi) for chi in self.v.children] all = hello print Will ret,all return all === I have tried passing return value in the decorator (return=int...). Any clues where to look? pyqt version is 4.9.1-2ubuntu1, on Ubuntu precise pangolin. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
