    <p>I apologize if this is a noob question, but I can't seem to figure this one out.</p> <p>I have defined an object that defines a music track (NOTE: originally had the just ATTRIBUTE vs self.ATTRIBUTE. I edited those values in to help remove confusion. They had no affect on the problem)</p> <pre><code>class Track(object): def __init__(self, title, artist, album, source, dest): """ Model of the Track Object Contains the followign attributes: 'Title', 'Artist', 'Album', 'Source', 'Dest' """ self.atrTitle = title self.atrArtist = artist self.atrAlbum = album self.atrSource = source self.atrDest = dest </code></pre> <p>I use ObjectListView to create a list of tracks in a specific directory</p> <pre><code>....other code.... self.aTrack = [Track(sTitle,sArtist,sAlbum,sSource, sDestDir)] self.TrackOlv.AddObjects(self.aTrack) ....other code.... </code></pre> <p>Now I want to iterate the list and print out a single value of each item</p> <pre><code>list = self.TrackOlv.GetObjects() for item in list: print item.atrTitle </code></pre> <p>This fails with the error</p> <pre><code>AttributeError: type object 'Track' has no attribute 'atrTitle' </code></pre> <p>What really confuses me is if I highlight a single item in the Object List View display and use the following code, it will correctly print out the single value for the highlighted item</p> <pre><code>list = self.TrackOlv.GetSelectedObject() print list.atrTitle </code></pre> <p>EDIT: Full source per request. To see error, browse to source dir w/ .mp3 files then click the print button.</p> <pre><code>#Boa:Frame:Frame1 import wx import os import glob import shutil import datetime from mutagen.mp3 import MP3 from mutagen.easyid3 import EasyID3 import mutagen.id3 import unicodedata from ObjectListView import ObjectListView, ColumnDefn ######################################################################## class Track(object): def __init__(self, title, artist, album, source, dest): """ Model of the Track Object Contains the followign attributes: 'Title', 'Artist', 'Album', 'Source', 'Dest' """ self.atrTitle = title self.atrArtist = artist self.atrAlbum = album self.atrSource = source self.atrDest = dest class Action(object): def __init__(self, timestamp, action, result): self.timestamp = timestamp self.action = action self.result = result ######################################################################## # Non GUI ######################################################################## def selectFolder(sMessage): print "Select Folder" dlg = wx.DirDialog(None, message = sMessage) if dlg.ShowModal() == wx.ID_OK: # User has selected something, get the path, set the window's title to the path filename = dlg.GetPath() else: filename = "None Selected" dlg.Destroy() return filename def getList(SourceDir): print "getList" listOfFiles = None print "-list set to none" listOfFiles = glob.glob(SourceDir + '/*.mp3') return listOfFiles def getListRecursive(SourceDir): print "getListRecursive" listOfFiles = None listOfFiles = [] print "-list set to none" for root, dirs, files in os.walk(SourceDir): for file in files: if file.endswith(".mp3"): listOfFiles.append(os.path.join(root,file)) #print listOfFiles return listOfFiles def strip_accents(s): print "strip_accents" return ''.join((c for c in unicodedata.normalize('NFD', s) if unicodedata.category(c) != 'Mn')) def replace_all(text): print "replace_all " + text dictionary = {'\\':"", '?':"", '/':"", '...':"", ':':"", '&amp;':"and"} print text print text.decode('utf-8') text = strip_accents(text.decode('utf-8')) for i, j in dictionary.iteritems(): text = text.replace(i,j) return text def getTitle(fileName): print "getTitle" audio = MP3(fileName) try: sTitle = str(audio["TIT2"]) except KeyError: sTitle = os.path.basename(fileName) frame.lvActions.Append([datetime.datetime.now(),fileName,"Title tag does not exist, set to filename"]) # TODO: Offer to set title to filename ## If fileName != filename then ## prompt user for action ## Offer Y/n/a sTitle = replace_all(sTitle) return sTitle def getArtist(fileName): print "get artist" audio = MP3(fileName) try: sArtist = str(audio["TPE1"]) except KeyError: sArtist = "unkown" frame.lvActions.Append([datetime.datetime.now(),fileName,"Artist tag does not exist, set to unkown"]) #Replace all special chars that cause dir path errors sArtist = replace_all(sArtist) #if name = 'The Beatles' change to 'Beatles, The' if sArtist.lower().find('the') == 0: sArtist = sArtist.replace('the ',"") sArtist = sArtist.replace('The ',"") sArtist = sArtist + ", The" return sArtist def getAblum(fileName): print "get album" audio = MP3(fileName) try: sAlbum = str(audio["TALB"]) except KeyError: sAlbum = "unkown" frame.lvActions.Append([datetime.datetime.now(),fileName,"Album tag does not exist, set to unkown"]) #Replace all special chars that cause dir path error sAlbum = replace_all(sAlbum) return sAlbum ######################################################################## # GUI ######################################################################## class MainPanel(wx.Panel): #---------------------------------------------------------------------- def __init__(self, parent): wx.Panel.__init__(self, parent=parent, id=wx.ID_ANY) self.TrackOlv = ObjectListView(self, wx.ID_ANY, style=wx.LC_REPORT|wx.SUNKEN_BORDER) self.setTracks() # Allow the cell values to be edited when double-clicked self.TrackOlv.cellEditMode = ObjectListView.CELLEDIT_SINGLECLICK self.ActionsOlv = ObjectListView(self, wx.ID_ANY, style=wx.LC_REPORT|wx.SUNKEN_BORDER) self.setActions() # create browse to source button sourceBtn = wx.Button(self, wx.ID_ANY, "Browse Source") sourceBtn.Bind(wx.EVT_BUTTON, self.onBrowseSource) # create source txt box self.txSource = wx.TextCtrl(self, wx.ID_ANY, name=u'txSource', value=u'') # create browse dest button destBtn = wx.Button(self, wx.ID_ANY, "Browse Destination") destBtn.Bind(wx.EVT_BUTTON, self.onBrowseDest) # create dest txt box self.txDest = wx.TextCtrl(self, wx.ID_ANY, name=u'txDest', value=u'') # create Move Files button moveBtn = wx.Button(self, wx.ID_ANY, "Move Files") moveBtn.Bind(wx.EVT_BUTTON, self.onMoveFiles) # print list button -

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
