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

[supersuraccoon]

I added some pixelmaps to a QGraphicsScene:

self.scene.addPixmap(cityPixmap)

self.scene.addPixmap(cityPixmap)

To copy to clipboard, switch view to plain text mode 

and it works fine...


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

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

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

To copy to clipboard, switch view to plain text mode 

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

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

To copy to clipboard, switch view to plain text mode 

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

Any reply will be appreciated, thanks
