Sort items in UltimateListCtrl

Question

I want to create a table with a limit list of ctrl, where the user can sort the columns by clicking on the column heading. Here is the code I tried:

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 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"), } ######################################################################## class TestUltimateListCtrlPanel(wx.Panel, listmix.ColumnSorterMixin): #---------------------------------------------------------------------- def __init__(self, parent): wx.Panel.__init__(self, parent, -1, style=wx.WANTS_CHARS, size=(MAIN_WIDTH,MAIN_HEIGHT)) self.index = 0 self.list_ctrl = ULC.UltimateListCtrl(self, -1, agwStyle=ULC.ULC_REPORT|ULC.ULC_HAS_VARIABLE_ROW_HEIGHT) self.list_ctrl.InsertColumn(0, "Artist") self.list_ctrl.InsertColumn(1, "Title", wx.LIST_FORMAT_RIGHT) self.list_ctrl.InsertColumn(2, "Download") items = musicdata.items() index = 0 for key, data in items: pos=self.list_ctrl.InsertStringItem(index, data[0]) self.list_ctrl.SetStringItem(index, 1, data[1]) #self.list_ctrl.SetStringItem(index, 2, data[2]) button = wx.Button(self.list_ctrl, id=wx.ID_ANY, label="Download") self.list_ctrl.SetItemWindow(pos, col=2, wnd=button, expand=True) self.list_ctrl.SetItemData(index, key) index += 1 # Now that the list exists we can init the other base class, # see wx/lib/mixins/listctrl.py self.itemDataMap = musicdata listmix.ColumnSorterMixin.__init__(self, 3) self.Bind(wx.EVT_LIST_COL_CLICK, self.OnColClick, self.list_ctrl) sizer = wx.BoxSizer(wx.VERTICAL) sizer.Add(self.list_ctrl, 1, wx.ALL|wx.EXPAND, 5) self.SetSizer(sizer) def GetListCtrl(self): return self.list_ctrl #---------------------------------------------------------------------- def OnColClick(self, event): pass ######################################################################## class MyForm(wx.Frame): #---------------------------------------------------------------------- def __init__(self): wx.Frame.__init__(self,None,wx.ID_ANY,'%sv%s' % (APPNAME,APPVERSION),size=(MAIN_WIDTH,MAIN_HEIGHT),style=wx.MINIMIZE_BOX | wx.SYSTEM_MENU | wx.CAPTION | wx.CLOSE_BOX | wx.CLIP_CHILDREN) # Add a panel so it looks the correct on all platforms panel = TestUltimateListCtrlPanel(self) #---------------------------------------------------------------------- # Run the program if __name__ == "__main__": app = wx.App(False) frame = MyForm() frame.Show() app.MainLoop()[/CODE] 

Clicking on a column doesn’t sort the "Artist" or "Title" fields. I want to be able to sort them when the user clicks on the column headers. Please, help.

Here is what it looks like

This seems to be a bug in the implementation of UltimateListControl. It does not update after clicking a column. This works for me:

 DATA = { 0 : ("3", "3", "1"), 1 : ("2", "1", "2"), 2 : ("1", "2", "3") } import wx import wx.lib.mixins.listctrl as listmix from wx.lib.agw import ultimatelistctrl as ULC class MyList(ULC.UltimateListCtrl, listmix.ColumnSorterMixin): def __init__(self, parent, columns): ULC.UltimateListCtrl.__init__(self, parent, agwStyle=ULC.ULC_REPORT | ULC.ULC_HAS_VARIABLE_ROW_HEIGHT) self.itemDataMap = DATA listmix.ColumnSorterMixin.__init__(self, columns) self.Bind(wx.EVT_LIST_COL_CLICK, self.OnColumn) def OnColumn(self, e): self.Refresh() e.Skip() def GetListCtrl(self): return self class MainWindow(wx.Frame): def __init__(self, *args, **kwargs): wx.Frame.__init__(self, *args, **kwargs) self.list = MyList(self, 3) self.list.InsertColumn(0, "A") self.list.InsertColumn(1, "B") self.list.InsertColumn(2, "C") items = DATA.items() for key, data in items: index = self.list.Append(data) self.list.SetItemData(index, key) self.Show() app = wx.App(False) win = MainWindow(None) app.MainLoop() 

Just for reference, it works as usual with a regular ListCtrl:

 DATA = { 0 : ("3", "3", "1"), 1 : ("2", "1", "2"), 2 : ("1", "2", "3") } import wx import wx.lib.mixins.listctrl as listmix class MyList(wx.ListCtrl, listmix.ColumnSorterMixin): def __init__(self, parent, columns): wx.ListCtrl.__init__(self, parent, style=wx.LC_REPORT) self.itemDataMap = DATA listmix.ColumnSorterMixin.__init__(self, columns) def GetListCtrl(self): return self class MainWindow(wx.Frame): def __init__(self, *args, **kwargs): wx.Frame.__init__(self, *args, **kwargs) self.list = MyList(self, 3) self.list.InsertColumn(0, "A") self.list.InsertColumn(1, "B") self.list.InsertColumn(2, "C") items = DATA.items() for key, data in items: index = self.list.Append(data) self.list.SetItemData(index, key) self.Show() app = wx.App(False) win = MainWindow(None) app.MainLoop() 

It can be fixed in newer versions of wxPython: http://trac.wxwidgets.org/changeset/68347
