[PyQt] Returning a subclass

Greetings,

here is the code:

class myAction (QtGui.QAction):
	def __init__ (self, parent, myProperty):
		QtGui.QAction.__init__ (self, parent)
		self.myProperty = myProperty

Later this myAction is instanced and added to a toolbar

someAction = myAction (self, "The Property")
self.toolbar.addAction(myAction)

Then in the end I want to iterate through all the actions in toolbar:

for a in self.toolbar.actions():
	print type(a)
	print a.myProperty

toolbar.actions() returns a list of QActions, is there a way to recast 
this QAction back to myAction? Is the information about subclass lost 
during this process? First print in the above code will print

<class 'PyQt4.QtGui.QAction'>

And the second will raise the AttributeError obviously.

Any ideas on this one?

Regards,
David
