start_editing

Description:

public abstract void start_editing (Event? event)

Begins editing on a this.

The CellRenderer for the cell creates and returns a CellEditable from start_editing, configured for the CellRenderer type.

start_editing can then set up this suitably for editing a cell, e.g. making the Esc key emit editing_done.

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

this	A CellEditable
event	The Event that began the editing process, or null if editing was initiated programmatically
