No, you don't call gtk_tree_model_row_changed() from you cell data function, but from you time out function, which updates the list store. And you call it on the list store. Anyway, you _can_ find which row the cell belongs to from the cell data function, that's what the `iter' argument is for. > Is there a way to force the redraw of the cell renderer? I think you misunderstand things. You cannot redraw a cell renderer, because cell renderer is merely an algorithm that draws cells. It is not bound to any specific cell or tree row or whatever.
