It doesn't work terribly well on wxMSW, wx 3.2.4 as well. `wxEVT_LEAVE_WINDOW` is only generated when crossing the thin border, or the search/cancel buttons. `wxEVT_MOTION` doesn't get generated inside the...

In 3.2.5, the provided `minimal.cpp.txt` still behaves the same for me. With this in `MyCustomRenderer` in `dataview`, row heights are inconsistent: ```cpp virtual wxSize GetSize() const wxOVERRIDE { return GetView()->FromDIP(wxSize(60,...

`master` branch behaves the same for me.

On MSW, the renderer's size doesn't matter, unless `wxDV_VARIABLE_LINE_HEIGHT` flag is set. Then it looks like this:
