<p>
This signal gets emitted when the user cancels the process of editing a
cell.  For example, an editable cell renderer could be written to cancel
editing when the user presses Escape.

<p>
This signal gets emitted when a cell starts to be edited.
The indended use of this signal is to do special setup
on <em class="parameter"><code>editable</code></em>, e.g. adding a <a class="link" href="GtkEntryCompletion.html" title="GtkEntryCompletion"><span class="type">GtkEntryCompletion</span></a> or setting
up additional columns in a <a class="link" href="GtkComboBox.html" title="GtkComboBox"><span class="type">GtkComboBox</span></a>.
</p>
<p>
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 <em class="parameter"><code>editable</code></em>
before doing any specific setup, as in the following example:
</p>
<p>
</p>
<div class="informalexample"><pre class="programlisting">
static void
text_editing_started (GtkCellRenderer *cell,
                      GtkCellEditable *editable,
                      const gchar     *path,
                      gpointer         data)
{
  if (GTK_IS_ENTRY (editable)) 
    {
      GtkEntry *entry = GTK_ENTRY (editable);
      
      /* ... create a GtkEntryCompletion */
      
      gtk_entry_set_completion (entry, completion);
    }
}
</pre></div>
