This signal gets emitted when a cell starts to be edited.
The intended use of this signal is to do special setup
on @editable, e.g. adding a #GtkEntryCompletion or setting
up additional columns in a #GtkComboBox.
Note that GTK+ doesn't guarantee that cell renderers will
continue to use the same kind of widget for editing in future
releases, therefore you should check the type of @editable
before doing any specific setup, as in the following example:
|[<!-- language="C" -->
static void
text_editing_started (GtkCellRenderer *cell,
GtkCellEditable *editable,
const gchar *path,
gpointer data)
{
if (GTK_IS_ENTRY (editable))
{
GtkEntry *entry = GTK_ENTRY (editable);
