Looks like I have found the solution. Here is the code for those who might come
across the same problem in the future.
We need to use gtk_bin_get_childe as the GtkEntry is actually nested in the
GtkCellRendererCombo itself.
Here is the code for completeness:
void testfunc(GtkCellRenderer *cell, GtkCellEditable *editable, const gchar
*path, gpointer data){
if (GTK_IS_ENTRY (gtk_bin_get_child(editable)))
{
GtkEntryCompletion *testComplete;
GtkEntry *entry = gtk_bin_get_child(editable);
testComplete = gtk_entry_completion_new();
gtk_entry_completion_set_model(testComplete, GTK_TREE_MODEL(myModel) );
gtk_entry_completion_set_text_column( testComplete, 0 );
gtk_entry_set_completion(GTK_ENTRY(entry),
GTK_ENTRY_COMPLETION(testComplete));
}
}
