サンプル GUIこんにちは、私は問題があります。誰かがそれを助けることができれば、それは素晴らしいことです。私はボーダーとグリッドレイアウトを使用しており、GUI を分割しようとしていますが、ボタンを全体のごく一部にしたいので、それは起こっていません。私もボタンを配置しようとしていますが、それが良い習慣であるかどうかはわかりません.2つのクラスがあります。1つはフレームのメインメソッドであるRunFurnitureで、もう1つはGUIのPanelFurnitureです。プログラムがコンパイルされ、実行されています。私は良い説明をしたことを願っています。これがコードです。

いくつかの追加の提案：

  • レイアウトにスペースを使用しないでください。配置を使用します。

  • コンポーネントの推奨サイズを使用して、レイアウトに作業を任せます。

  • 可能な場合は構成を使用してくださいfor-each。

  • EDTで開始します。

最新の編集:

JPanel上のLINE_STARTまたはWESTは と一緒に使用する必要がGridLayoutあり、CENTERJPanel はこれらの画像に対応するために使用できますGridLayout:-) . あなたがこの回答を受け入れたとき、そして@AndrewThompsonが物に関するコメントを追加したとき、私はそれに取り組んでいましたがGridLayout、JPanelをGridLayoutに配置すると、同じサイズのJButtonが許可されるようです。GridLayoutコード内での私の解釈は次のとおりです。
