CellEditableIF.addOnRemoveWidget

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 #GtkCellEditable::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.
