As soon as you click anywhere outside the area with suggestions
(matching entries), the overview of suggestions disappears. This means
that users can never hover over a suggestion to highlight it and then
press a delete button. Unless I'm misunderstanding what you have in
mind.

Anyway, why not add a button to open a completely new window that allows
users to remove suggestions from a tree view. This should also allow
them to remove multiple entries at once. Another, lazier solution,
could be to add a delete button that will delete the suggestion
matching what's currently in the entry.

Something else that may or may not be possible, is add a
g_signal_connect (entry, "key_press_event", G_CALLBACK (Delete), NULL);
and then check in Delete()
if (strcmp (gdk_keyval_name (event->key.keyval), "Delete") == 0)
and if that's the case, somehow obtain the active suggestion.
The problem here is that a GtkEntryCompletion only contains only
private data. At least, I think.
I tried using
selection = gtk_tree_view_get_selection (GTK_TREE_VIEW
(completion->priv->tree_view_proposals));
to get a selection, but this doesn't seem to work.

Best regards,
