Sort items in UltimateListCtrl

wxPython Users
1

I want to create an ultimate list ctrl based table where the user can
sort the columns by clicking on the column header. Here's the code I
attempted:

import wx
import wx.lib.mixins.listctrl as listmix
from wx.lib.agw import ultimatelistctrl as ULC

APPNAME='Sortable Ultimate List Ctrl'
APPVERSION='1.0'
MAIN_WIDTH=300
MAIN_HEIGHT=300

musicdata = {
0 : ("Bad English", "The Price Of Love"),
1 : ("DNA featuring Suzanne Vega", "Tom's Diner"),
2 : ("George Michael", "Praying For Time"),
3 : ("Gloria Estefan", "Here We Are"),
4 : ("Linda Ronstadt", "Don't Know Much"),
5 : ("Michael Bolton", "How Am I Supposed To Live Without You"),
6 : ("Paul Young", "Oh Girl"),
}

#----------------------------------------------------------------------
# Run the program

    frame = MyForm()
    frame.Show()

Clicking on the column does not sort the 'Artist' or 'Title' fields. I
want to be able to sort them when the user clicks on the column
headers. Please help.

I tried it. No change. It still doesn't sort. Not sure what else can I
do.

Works for me, i.e. column 1 and 2 sort, but column 3 throws an exception as your musicdata/itemDataMap doesn't have any data for your button.

I am on Windows 7 with Python 2.7 and wx.Python 2.9.2.4 with wx.lib.agw from SVN.

It works for me to after adding self.Refresh() to OnColClick like this:
