[PyQt] QListView Global funcation behaviour

[klia]

hey folks;

I am trying to list photos on QlistView by browsing using Qfiledailoug...
so far i was doing the following 

filename = QtGui.QFileDialog.getOpenFileName(self, 'Open file','/home/')
#this one calls the file dailoug for browsing
		filename = [] # this one is an array to hold selected files
		filename = listViewitem1() # this one is suppose to list the files on
listview

anyway i was getting an error saying that there is no global name for
(listViewitem1), so i had to define a global function for it. here it's

filename = QtGui.QFileDialog.getOpenFileName(self, 'Open file','/home/')
		filename = []
		filename = listViewitem1(filename, self)

class listViewitem1(QAbstractListModel): 
	def __init__(self, datain, parent=None, *args):
	   """ datain: a list where each item is a row
	   """
	   QAbstractTableModel.__init__(self, parent, *args)
	   self.filename = datain
	
	def rowCount(self, parent=QModelIndex()):
		return len(self.filename)
	
	def data(self, index, role):
		if index.isValid() and role == Qt.DisplayRole:
		    return QVariant(self.filename[index.row()])
		else:
			return QVariant()

Then it runs with no errors but when i browse through my directory and
select a file, nothing happens (no file is listed on QListView) and no
errors occurred either. 

Any ideas will be so helpful
Thank you
