私は wxPython アプリケーション (以下のドキュメント) を作成しました。チェックボックスやテキストラインなど、私が望むすべての方法があります。唯一の問題は、これをアプリケーションのメイン フレームとして作成したことです。

私が本当に望んでいるのは、これをウィジェットに変換して、最終的なアプリケーション フレームでそれらのいくつかをインスタンス化できるようにすることです。しかし、wx.Frame ではなく wx.Panel からウィジェットを継承させてから、ウィジェットを Frame クラスにインスタンス化しようとすると、中性子星のように崩壊しました。

私の 2 つのコード例を見て、何が問題なのかを確認してください。

これは、私のウィジェットが wx.Frame から継承するクラスに直接組み込まれているバージョンです。

繰り返しますが、最初のコード サンプルは基本的に希望どおりに動作しますが、最終的なプログラムでは 1 つのウィジェットにする必要があります。wx.Frame から継承するクラスでそれをインスタンス化しようとすると、書式設定が消えてすべてが重なり合うのはなぜですか?

よろしくお願いします。他に提供する必要がある情報があれば教えてください。

コードをフレームからカスタムパネルに変換したときに、余分なパネルを削除するのを忘れていました。ISC_status（wx.Panel）は、追加のサイザーが不足しているため、内部に別のパネルを作成しました。レイアウトは無視されました（メインフレームがレイア​​ウトを再計算したときに、内部パネルに到達できませんでした）。

その内側のパネル（およびそれを小さく保つためのいくつかの機能、申し訳ありません）を削除しました。これで、希望どおりに機能するはずです。
