Forwarding DataViewCustomRenderer calls to existing renderers

I am using a custom renderer for the ability to return different types of controls based on the data.

I am not entirely aware of GTK’s API, but this answer mentions how a custom cell renderer can forward calls to existing implementations. Looking at the answer it seems the wx implementation is very similar to GTK.

I tried using DataViewTextRenderer.CreateEditorCtrl in my implementation and passed it the correct arguments. But it returns None instead
