<div class="moz-text-flowed" style="font-family: -moz-fixed"> Editing a column value in a report mode list control seems to be properly
working, but I cannot get the changed value to display. I suspect it has
something to do with the use of SetStringItem().

  Here is the method (with debugging print stubs):

      def OnRuleEdit(self, event):
            # copy contents of row for each column to var names
        idx = self.rulesList.GetFirstSelected()
        print 'Initial row number: ', idx
        self.co = self.rulesList.GetItem(idx,0).GetText()
        self.su = self.rulesList.GetItem(idx,1).GetText()
        self.va = self.rulesList.GetItem(idx,2).GetText()
        self.rn = self.rulesList.GetItem(idx,3).GetText()
        print 'Loading values: ', self.rn
        self.ru = self.rulesList.GetItem(idx,4).GetText()

        modRule = ruleDlg()
        modRule.pName.SetValue(self.co)
        modRule.sName.SetValue(self.su)
        modRule.vName.SetValue(self.va)
        modRule.rNum.SetValue(self.rn)
        modRule.rule.SetValue(self.ru)
        result = modRule.ShowModal()
        if result == wx.ID_OK:
          self.co = modRule.pName.GetValue()
          self.su = modRule.sName.GetValue()
          self.va = modRule.vName.GetValue()
          self.rn = modRule.rNum.GetValue()
          self.ru = modRule.rule.GetValue()
          # Replace changed values
          self.rulesList.InsertStringItem(idx, self.co)
          print 'Row number: ', idx
          self.rulesList.SetStringItem(idx, 1, self.su)
          self.rulesList.SetStringItem(idx, 2, self.va)
          self.rulesList.SetStringItem(idx, 3, self.rn)
          print 'Writing values: ', self.rn
          self.rulesList.SetStringItem(idx, 4, self.ru)
        modRule.Destroy()

  No python errors generated when I run the application. The outputs of the
print statements are:

Initial row number: 4
Loading values: WTH
Row number: 4
Writing values: WTH2

  However, 'WTH2' does not display; it remains 'WTH'. The code in the 'if'
loop is the same as that in the add method, so I do not understand why the
new value does not replace the original value in the displayed list control.

TIA,

Rich

I suspect the issue is because of your "self.rulesList.InsertStringItem(idx, self.co)" line. I just use SetStringItem() myself. For some reason, I set the state to selected before I use the SetStringItem method...I don't recall why.

self.list_ctrl.SetItemState(cnt, wx.LIST_STATE_SELECTED, wx.LIST_STATE_SELECTED)

You can try that with or without the above.

Mike,

  As my second message indicated, the changed row _was_ inserted, but as a
new row rather than as a replacement. Might I need to set the state to
'selected' to have the modified row replaced?

Thanks,

Rich

Yeah, I saw that, which is why I pointed out that line. I that's what that method does. It inserts new rows at the end. And I think you're likely right. It probably does require it to be set to "selected" before changing it. You can give it a go and find out.

Maybe Robin or one of the Chris's will have insight into the matter.
