Hi,
A year ago i found a bug in FastObjectListView and no-one from the ObjectListView discussion replayed,
i wonder if ObjectListView is dead.if so are there any good alternatives?
Many thanks!

Where did you post it?
I had pretty quick replies when I had a question. Last post I can see from Philip is in Dec 2009 on the following.

For alternatives, you should probably look at the listctrl's in the AGW "series" - haven't used them myself yet.

What exactly are the bugs? I am fairly familiar, I will write a patch
if I can...
I use it quite a bit..Haven't found anything that compares yet...
We will see what we can do with the new DataViewCtrl though once 2.9
hits the shelf.

Well the bug is that the sorting is not working when after using SetFilter on a FastObjectListView table.

looking forward for it!
here is an example of the problem:
mport wx
from ObjectListView import FastObjectListView,ColumnDefn
def evenFilter(numbers):
return [num for num in numbers if num % 2 != 0]
a = wx.App(None)
f = wx.Frame(None,-1)
folv = FastObjectListView(f,-1)
folv.AddColumnDefn(ColumnDefn(title=‘pop’,valueGetter=lambda o:o))
folv.SetObjects(range(500))
folv.SetFilter(evenFilter)
folv.RepopulateList()
f.Show()
a.MainLoop()
try sorting the list…

Yoav,
The Problem:
FastOVL keeps two lists of the items, the underlying list from
SetObjects(), and then an 'innerlist' that it actually displays.
This is how it does filtering/groups/etc without disturbing the
underlying data.
However, for sorting it actually sorts the underlying list without
updating the 'innerlist' (not sure why)
a simple fix is to add in ObjectListView.py:
self._BuildInnerList()
after line 2522 (right after self._SortObjects() in
FastObjectListView's _SortItemsNow)
[This will be line 2543 in the latest SVN checkout.]
However I believe it might be of benefit to change the way the sorting
happens so only the view/innerlist is sorted as in this case we are
sorting a list twice as large.
I will look into making these changes and submitting this to the
author (this will be a good prod to polish up some of the other
changes I have made and submit those as well)
If you have any problems making these changes just let me know what
OLV version you're using and i'll send you an acutal patch or a
modified ObjectListView.py
Also in your example, don't call RepopulateList right after you call
SetObjects, you should call SetFilter and then SetObjects (you are
building the list twice):
import wx
from ObjectListView import FastObjectListView,ColumnDefn
def evenFilter(numbers):
return [num for num in numbers if num % 2 != 0]
a = wx.App(None)
f = wx.Frame(None,-1)
folv = FastObjectListView(f,-1)
folv.AddColumnDefn(ColumnDefn(title='pop',valueGetter=lambda o:o))
folv.SetSortColumn(0)
folv.SetFilter(evenFilter)
folv.SetObjects(range(500))
f.Show()
a.MainLoop()

self._BuildInnerList()
after line 2522 (right after self._SortObjects() in
FastObjectListView’s _SortItemsNow)
[This will be line 2543 in the latest SVN checkout.]
I rather not change the source since we are working in a team. (ObjectListView is 3rd party for us)
I will look into making these changes and submitting this to the

Sounds Great!
Also in your example, don’t call RepopulateList right after you call

building the list twice):
thats just an example… =) not real code.

Just modify the code and include the source inside your program's source, and import that, rather than the installed OLV. Then, everyone has the same version

Hi there,
ObjectListView is not dead -- it's just resting 
To be honest, apart from a few small patches (thanks Werner), I
haven't found much more that I need to do with this control. It does
just about everything that is possible with the current wx.ListView.
When we get a control that supports owner drawing, then I can do some
really neat stuff! Until then, I'd almost be tempted to say that it's
finished.
If I missed your post on the discussion, I'm sorry.
Regards,
Phillip
