[wxpython-users] Fwd: Trouble with CheckListCtrl

[Raffaello Barella]

If you want to call a function when an item is checked, you have to
intercept an event (usually, I think, wx.EVT_LIST_ITEM_SELECTED or
wx.EVT_LIST_ITEM_DESELECTED). So put in the __init__ of your frame the
following:

          self.Bind(wx.EVT_LIST_ITEM_SELECTED, self.OnSelectedItem,
self.chkList)

and then build your function:

   def OnSelectedItem(self, event):
          event.Skip() # look the documentation for this command
          do stuff...
