[wxPython-users] Confusing ListCtrl behavior.

[Rudolf Gärtner]

Try the following solution:


    def evt_selected(self, event):
        wx.CallAfter(self.selectIt, event.m_itemIndex)

    def selectIt(self, new_select):
        if self.cur_select is not None and new_select != self.cur_select:
            dlg = wx.MessageDialog(self,
                                   'Allow selection to change?',
                                   'Some Dialog',
                                   wx.YES|wx.NO|wx.CENTRE|wx.ICON_WARNING)

            answer = dlg.ShowModal()

            if answer == wx.ID_NO:
               self.list_ctrl_1.SetItemState(new_select,
                                             0,
                                             
wx.LIST_STATE_FOCUSED|wx.LIST_STATE_SELECTED,
                                             )

               self.list_ctrl_1.SetItemState(self.cur_select,
                                             
wx.LIST_STATE_FOCUSED|wx.LIST_STATE_SELECTED,
                                             
wx.LIST_STATE_FOCUSED|wx.LIST_STATE_SELECTED,
                                             )
               return

        self.cur_select = new_select
        self.list_ctrl_1.Focus(new_select)
