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])

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
