DataViewCtrl How to scroll programmatically

1

I want to scroll a DataViewCtrl programmatically to the top. Is it possible to do this? I am aware of the discussion at:
DataViewCtrl: how to scroll programmatically? (wxGTK) but my model is not a PyDataViewIndexListModel so the work around mentioned there would not work for me.

What I really need is to get the first item in the control according to the current sorting. I can get what I want by calling GetTopItem() which returns the top-most visible item. This gives me the answer I want when the control is scrolled to the top, but not otherwise. Hence my idea of first scrolling to top and then invoking GetTopItem() but I haven’t been able to figure out how to scroll a DataViewCtrl programmatically.

While ScrollToTop would still a well defined operation in an arbitrary DataViewCtrl, I have concluded that it is more logical in my case, and probably in a majority of cases, to choose an Item (e.g. using the model’s Compare method) and then ensure the item is visible using the control’s EnsureVisible method.
