I don't think a better way is possible really.  Cell renderers basically
just render the content in your model on the screen in some way and when
they are clicked they emit a signal.  These renderers usually never
directly modify the model or have any logic that they need additional
model data for.  It also does not keep track of the currently "active"
toggle item, for this a cell renderer would have to monitor the model
which is something cell renderers are not supposed to be doing.


So yes, you will have to implement the logic for toggling yourself.
