pub trait CellEditableExtManual {
    fn start_editing(&self, event: Option<&impl AsRef<Event>>);

Required methods

Begins editing on a @self.

The CellRenderer for the cell creates and returns a CellEditable from gtk_cell_renderer_start_editing(), configured for the CellRenderer type.

gtk_cell_editable_start_editing() can then set up @self suitably for editing a cell, e.g. making the Esc key emit GtkCellEditable::editing-done.

Note that the @self is created on-demand for the current edit; its lifetime is temporary and does not persist across other edits and/or cells.


The gdk::Event that began the editing process, or None if editing was initiated programmatically
