[Pythoncard-users] Grid component

Hi.  I need some help with the Grid component.  
   
  Here is the code that I'm working with:
   
      self.components.grdDataGrid.EnableEditing(False)
   
      def on_grdDataGrid_mouseDoubleClick(self, event):
        self.components.grdDataGrid.EnableEditing(True)
        event.skip()
   
      def on_grdDataGrid_selectCell(self, event):
        self.components.grdDataGrid.EnableEditing(False)
        event.skip()
        
    def on_grdDataGrid_keyDown(self, event):
        self.components.grdDataGrid.EnableEditing(False)
        event.skip()
   
      def on_grdDataGrid_editorShown(self, event):
        result = dialog.messageDialog(self, "Are you sure you wish to edit this cell?","Edit", wx.YES_NO)
        if not result.accepted:
            event.Veto() 
            self.components.grdDataGrid.EnableEditing(False)
            return
        event.skip()
   
      def on_grdDataGrid_editorHidden(self, event):
        result = dialog.messageDialog(self, "Are you sure you wish to save the changes?","Save", wx.YES_NO)
        if not result.accepted:
            event.Veto()
            return
        event.skip()

   
  I would like to allow editing only if the user double clicks in the cell.  After editing a cell and using enter or tab to exit the cell, the dialog associated with the editorHidden event pops up twice.  I only want it to pop up once.  Any help would be appreciated.  Thanks.
