Thanks for the hint

but i have QGraphicsview widget not graphicscene, how can i implement
QgraphicsPixmapItem?

so far i came with this, is it correct?
files = QFileDialog.getOpenFileNames(self, self.trUtf8("Add documentation"),
> QString("/home"), self.trUtf8("Images (*.png *.tiff *.jpg)")) 
> 		for file_ in files:
> 			data = ""

> 			#data = file.read()
> 			self.listWidget.addItem(file_)
		self.listWidget.setItemSelected(file_)
		self.my_list_item.text(file_)
		self.photosdisplay.addPixmap(file_)

but nothing happened when i clicked?
