[pyqt]Tag for items in QGraphicsScene???...

[supersuraccoon]

I added some pixelmaps to a QGraphicsScene:



self.scene.addPixmap(cityPixmap)


and it works fine...


Then I usa for loop to get all the pixelmap like this:



for obj in self.scene.items():
print 'obj'


this also works fine...


But my question is:

say I add some city pixelmaps and some river pixelmaps to the scene, now I want to remove all the river pixelmaps:



for obj in self.scene.items():
if type(obj) == QGraphicsPixmapItem:
#do the remove stuff


but how I can tell the QGraphicsPixmapItem object I got is a river or a city ?

Any reply will be appreciated, thanks:)
