これは、私が想定していたよりもはるかに困難であることが判明しています。私がしたいのは、この JPanel をフレームの左側に「貼り付ける」ことだけです。これが私がこれまでに持っているものです。(可能であれば GridBagLayout を使用したくありません (私は Java 初心者です))。

labels = new JPanel();
JLabel currentWordLA = new JLabel("Current word:");
JLabel triedLettersLA = new JLabel("Tried letters:");
JLabel triesLeftLA = new JLabel("Tries remaining:");
JButton restart = new JButton("Reset");

labels.setLayout(new BoxLayout(labels, BoxLayout.Y_AXIS));
labels.add(currentWordLA);
labels.add(triedLettersLA);
labels.add(triesLeftLA);
scorePanel.add(labels, BorderLayout.WEST);

編集：申し訳ありませんが、これが完全なコードです。フレーム内のパネル内のパネルのようなものです。フレームを左に揃えようとしています。ありがとう！

次のように、BorderLayout.CENTER に何かを追加してみてください。

    scorepanel.add(new JPanel(), BorderLayout.CENTER); //I guess scorepanel is your frame
    //your code here

私はあなたのレイアウトが好きです。あなたの例にいくつかの変更を加えました：

  • 絵を描くだけのようMyDrawPanelです。をオーバーライドすると、たくさん呼び出す代わりにgetPreferredSize使用できます。内で、パネルのとを基準にして描画を行うと、どのサイズでも正しく表示されます。pack()setSize()paintComponentgetWidthgetHeight

  • ラベルに使用JLabel.LEFTし、レイアウトがどこにあるかがわかるように背景色を灰色にしました。ここにもっとあります。

  • のような標準的な命名を使用するとMyDrawPanel、他の人がコードを読みやすくなります。
