Pythonでtkinterを使ってログインページを作る

-1

入力した内容が正しい限り、ユーザーがログインボタンを押したときに新しいフレームを読み込もうとしています。コードが正しく実行されているかどうかを確認するために、LogInCheck関数内にprintコマンドを含めました。私の唯一の問題は、フレームを変更しないことです。あなたはそれの残りの部分を見てする必要がある場合、私は私の完全なコードが含まれますPythonでtkinterを使ってログインページを作る

私はそれはかなり厄介だ知っていて、他のエラーがあるかもしれませんが、今の私はちょうどそれが正常にログインした後のフレームを変更する文句を言わない理由を把握する必要があります。

こんにちはJamesオーバーフローを歓迎します。あなたの状況については、[最小限の完全で検証可能な例]（https://stackoverflow.com/help/mcve）を提供する必要があります。私たちが必要とするのは、フレームを前面に動かすボタンを備えた単一のウィンドウです。私たちはすべてのコードを必要としません。ちょうどその質問に関連するもの。 –

表示されている問題は、LoginクラスがPhoneCompanyメソッドshow_framesを呼び出そうとしていることが原因です。 Loginクラスにはそのようなメソッドはありません。 –

それで、PhoneCompanyクラスからshow_frames関数をログインクラスにコピーするのは簡単ですか？編集：私は思ったように単純ではない、それを試みた –

self.controller.show_frame(StartPage)である必要があります。
