Gtk.CellRendererMode

Identifies how the user can interact with a particular cell.

CellRendererMode.INERT

The cell is just for display and cannot be interacted with. Note that this doesn't mean that eg. the row being drawn can't be selected -- just that a particular element of it cannot be individually modified.

CellRendererMode.ACTIVATABLE

The cell can be clicked.

CellRendererMode.EDITABLE

The cell can be edited or otherwise modified.
