Hello,
I am using a wx.lib.agw.HyperTreeListCtrl, and i would like to sort the list by clicking on the header of one of its columns.
I know of wx.lib.mixins.listctrl.ColumnSorterMixin, which is made to work with wx.ListCtrl.
My question is : is it worth for me to look into it, or is it just impossible to make them work together ?
Thank you !
PS: I discovered the ObjectListView**,** which seems nice (includes sorting for ex.) but doesn’t have a tree display.
I don't have a solution Tom, but I am interested in doing the exact same thing.
If find a solution, I sure would appreciate you posting back here.

Hello list,
I have gone another way in order to sort the items in my HyperTreeList.
I try to override the method OnCompareItems of my subclass of HyperTreeList, so that the method SortChildren will sort the items the way i want.
However i was not successful until now, so built a small example of what i have that is not working (see below).
My problem must be that i don’t understand overriding well enough, so can someone point me in the right direction ?
The method OnCompareItems() is not even called.
Cheers.
Thomas.

root = self.tree.AddRoot("")
itemA = self.tree.AppendItem(root, 'A')
self.tree.SetItemText(itemA, '1000', 1)
itemB = self.tree.AppendItem(root, 'B')
self.tree.SetItemText(itemB, '10', 1)
itemC = self.tree.AppendItem(root, 'C')
self.tree.SetItemText(itemC, '100', 1)
self.tree.SetMainColumn(0)
self.tree.ExpandAll()
self.tree.SortChildren(root)

self.AddColumn("Name")
self.AddColumn("Rank")

app.MainLoop()

I have gone another way in order to sort the items in my HyperTreeList.
I try to override the method OnCompareItems of my subclass of HyperTreeList,
so that the method SortChildren will sort the items the way i want.

...

...
def OnCompareItems(self, item1, item2):
print "Comparing now!"
return cmp(self.GetItemText(item1, 1), self.GetItemText(item2, 1))
This is somewhat counterintuitive -- or rather to be taken
literally. SortChildren sorts *children*, not Grandchildren
or the like...
So, in effect, you need to traverse the tree and
SortChildren() manually on each node having children 
At least that works for me with a standard tree control.

Thanks for your reply Karsten, but sorting all the children of root
was actually what i was trying to do. Then the children of those
(grand-children of the root) would follow their parent, which are being
sorted.
Ok i found out what was the problem, and i will explain it with my limited vocabulary!
Overriding was done without a problem on the wx.gizmos.TreeListCtrl (for example), so it is just that the HyperTreeList does not allow overriding.
Actually there was another post about this by Frank Niessink who proposed a way to override the functions of HyperTreeList (i think).
So sorting the children of root in a HyperTreeList is not possible through overriding OnCompareItems(), and calling SortChildren() (Yet!).
Can anybody give me an other option for sorting a HyperTreeList ?
Thanks in advance,
Thomas.
