Gtk.CellEditable::editing-done

function callback(cell_editable, ):void;

This signal is a sign for the cell renderer to update its value from the @cell_editable.

Implementations of Gtk.CellEditable are responsible for emitting this signal when they are done editing, e.g. Gtk.Entry is emitting it when the user presses Enter.

Gtk.CellEditable.prototype.editing_done is a convenience method for emitting Gtk.CellEditable::editing-done.
