java - Java Swing NimbusでJButtonのサイズを設定するには?

Question

GUI でボタンを同じサイズにしようとしています。ただし、PreferredSize() を設定するたびに、Nimbus はいくつかのボタンの高さを自動的に設定するようです。Nimbus にすべてのボタンを同じサイズ (つまり、幅と高さ) にさせる最良の方法は何ですか? 以下のサンプルコードでは、最初の行のボタンの高さは正しくなっていますが、幅は正しくありません。2 行目では、幅は正しいのですが、高さが正しくありません。Nimbus ですべてのボタンを同じサイズで表示するにはどうすればよいですか?

サイズを標準化する 1 つの方法は、コンポーネントをGridLayout. 詳細については、コンテナ内のコンポーネントのレイアウトを参照してください。

..PreferredSize() を設定するたびに、

ところで - 優先サイズを設定する必要があることはめったにありません。レイアウトマネージャー (適切なパディングと境界線を使用) に、さまざまな画面解像度、サイズ、PLAF、およびバージョンにわたってコンポーネントの正しいサイズを計算するという面倒な作業を任せます。

あなたは正しいNimbusかなりバグがあり (開発は第 1 四半期のどこかで終了しました)、場合によってはの設定が無視されます。これが、コンポーネントのサイズ変更PreferredSizeがある理由です。

これが私が例を表示したかった方法です。GroupLayoutを使用するとうまくいきました。ニンバスLAFに正しく表示されます。助けてくれてありがとう。GridBagLayoutの好みを再考する必要があると思います。
