This signal is meant to indicate that the cell is finished
editing, and the widget may now be destroyed.
Implementations of GtkCellEditable are responsible for
emitting this signal when they are done editing. It must
be emitted after the "editing-done" signal,
to give the cell renderer a chance to update the cell's value
before the widget is removed.
gtk_cell_editable_remove_widget() is a convenience method
for emitting GtkCellEditable::remove-widget.
