python - PyQt4: Sorting a QTableWidget by a column containing an icon -

i have database list of items, , each item has associated "rating" field, float ranging 0-5. now, when i'm populating qtablewidget these items, want display image rating instead of float. this:

iconpath = "images/icons/ratings/"+backend.utilities.pickratingicon(col) icon = qtgui.qicon(qtgui.qpixmap(iconpath)) item = qtgui.qtablewidgetitem(icon, "") self.decktable.setitem(i, j, item) 

everything works, naturally lose ability sort column. can change third line this:

item = qtgui.qtablewidgetitem(icon, col) 

which allows me sort again, float next icon kind of defeats purpose. there way display icon sort value?

first of must store ratings.

item = qtgui.qtablewidgetitem(icon, "") self.decktable.itemsrating[item]=rating self.decktable.setitem(i, j, item) 

and override sortitems subclassed qtablewidget , manually rearrange items:

class decktablewidget(qtgui.qtablewidget): itemsrating=dict() def sortitems(self, column, order=qtcore.qt.ascendingorder):   _list=[]   row in self.rowcount():       item = self.takeitem(row, column)       _list.append((item, self.itemsrating[item]))   _list.sort(lambda x,y: cmp(x.[1], y.[1])   if order != qtcore.qt.ascendingorder:       _list.reverse()   row in self.rowcount():       self.setitem(row, column, _list.pop()[0])
