Additionally, the user can write own renderers by deriving from

- The @e wxDataViewCellMode flag controls, what actions
- the cell data allows. @e wxDATAVIEW_CELL_ACTIVATABLE
- indicates that the user can double click the cell and
- something will happen (e.g. a window for editing a date
- will pop up). @e wxDATAVIEW_CELL_EDITABLE indicates
- that the user can edit the data in-place, i.e. an control
- will show up after a slow click on the cell. This behaviour
- is best known from changing the filename in most file
- managers etc.
