私はかなりpythonとtkinterの新機能です。私は私のスキルを構築するために努力していますので、私はラズベリーパイをプログラムすることができます。私の現在の問題は私に悩まされました：私は、エントリフィールドをクリックすると、ダイアログボックス（画面キーボード）を表示したい。呼び出し可能なTkinterのToplevelポップアップダイアログ
私はこれを実現するためにいくつかの方法を試しました。キーボードを最初に表示するか、まったく表示しないようにすることができます。しかし、クリックイベントではありません。私は、キーボードクラスがそれ自身で作業していることを知っているので、私はそれをどのように呼び出すのか（popout.pyの29行目）でなければなりません。

を私は本当にこれらの例外を取得するために何が起こっているのか理解していない：私は、私が実装しようとする方法に基づいて2つのエラーメッセージのいずれかを取得します。以下は私のコードです：
