次のコードでは、NotesPanel を保持する JFrame のサイズが変更されたときに、NotesPanel 内にあるパネルのサイズを変更しようとしています。

実行可能な CSSE:

package com.protocase.notes.views;

        JFrame f= new JFrame();     
        f.setSize(500,500);
        Note note = new Note();
        User u = new User();
        note.setCreator(u);
        note.setLastEdited(u);
        note.setDateCreated(new Date());
        JPanel panel = new JPanel();
        panel.add(new NotesPanel(note, null));
        panel.add(new NotesPanel(note, null));
        panel.setBackground(Color.red);

        f.setVisible(true);

        this.setLayout(new BoxLayout(this,BoxLayout.Y_AXIS));
        this.setBorder(new BevelBorder(BevelBorder.RAISED));



        // -- Setup the creator section.
        JLabel creatorLabel = new JLabel("Note by "+note.getCreator()+ " @ "+note.getDateCreated());
        creatorLabel.setAlignmentX(JLabel.LEFT_ALIGNMENT);


        // -- Setup the notes area.
        JTextArea notesContentsArea = new JTextArea(note.getContents());
        notesContentsArea.setEditable(false);
        notesContentsArea.setLineWrap(true);
        notesContentsArea.setWrapStyleWord(true);

        JScrollPane scrollPane = new JScrollPane(notesContentsArea);
        scrollPane.setAlignmentX(JScrollPane.LEFT_ALIGNMENT);

        // -- Setup the edited by label.
        JLabel editorLabel = new JLabel(" -- Last edited by "+note.getLastEdited() +" at "+note.getDateModified());
        editorLabel.setAlignmentX(Component.LEFT_ALIGNMENT);

        // -- Add everything to the view.
        Dimension wD = new Dimension(Short.MAX_VALUE, Short.MAX_VALUE);
        scrollPane.setMaximumSize(wD);
        this.setBackground(Color.yellow);
        this.setMaximumSize(wD);
        this.add(creatorLabel);
        this.add(scrollPane);
        this.add(editorLabel);
    }
    //</editor-fold>

}

編集:これは BoxLayout の問題です。最大サイズを設定しても何のメリットもないようです。

すべてが適切にサイズ変更されているため、問題がどこにあるのかわかりません。

これは、さまざまなウィンドウサイズで私がどのように見えるかのスクリーンショットです。 1 2 3

どのような違いを達成したいですか？
