My button renderer listens for the click event and then dispatches a custom event containing the row data and the renderer's configured action string. I guess there could be a cleaner way of doing this (overrinding the button's clickHandler method?) but I must admit that I haven't changed it as it works and I have plenty of other stuff to be getting on with! > As for the updateDisplayList, I suggest you read up on what it's for and > just how important it is... I understand what updateDisplayList does. I am simply confused as to why all the button renderers are being continually redrawn when their size, position and visual appearance haven't changed! Nick.
