请问：我用wxpython编的gui，当窗体有效时打开（新建）一个zodb库，我想在关闭窗体时关闭数据库，
如：def OnWxframe1Activate(self, event):
        storage = FileStorage.FileStorage('record.fs') 
        db = DB(storage)
        conn = db.open()
        dbroot = conn.root()
        dbname = 'recordlist'
        dbroot[dbname]=OOBTree()
        list = dbroot[dbname]
        class record(Persistent):
 
 
        def OnWxframe1Close(self, event):
            db.close()
            self.Close()
            self.Destroy()
        
为何说db这个变量不是全局变量，那我又如何调用db这个变量呢

Hello Nature.Liu,

self.db = DB(storage)
....

self.db.close()


是也乎？
