Virtualvfunc_Emits the Gtk.CellEditable::editing-done signal.
Virtualvfunc_Emits the Gtk.CellEditable::remove-widget signal.
Virtualvfunc_Begins editing on a cell_editable.
The Gtk.CellRenderer for the cell creates and returns a Gtk.CellEditable from
gtk_cell_renderer_start_editing(), configured for the Gtk.CellRenderer type.
gtk_cell_editable_start_editing() can then set up cell_editable suitably for
editing a cell, e.g. making the Esc key emit Gtk.CellEditable::editing-done.
Note that the cell_editable is created on-demand for the current edit; its
lifetime is temporary and does not persist across other edits and/or cells.
Interface for implementing CellEditable. Contains only the virtual methods that need to be implemented.
