CardLayoutにChartPanelを追加する

Question

私はかなり基本的なGUIをGridBagLayoutで編成しました。最も複雑な部分は、WestにScrollPaneが埋め込まれた下部で、右はCardLayoutのPanelで、複数のChartPanelsを持つため、いくつかのグラフを切り替えることができます。

プログラムを起動するときに問題が発生します。

サイズ変更の問題は、私は任意の方向にフレームのサイズを変更した後に消えます。 CardLayoutパネルにこれを追加してもパネルが修正されないので、チャートパネルが問題であることを確認しました。私は空白のChartPanelを作成して、いくつかのアクションが取られた後に、後でそれを取り込むが、これは私がやったことです：

public class Tester { 
    public static void main(String[] args) { 
     JFrame frame = new JFrame("Chipmunk: Variant Data Collection Tool"); 
     JPanel hotspotPanel = new JPanel(new CardLayout()); 
     ChartPanel subHotspotPanel = new ChartPanel(null); 
     JPanel indelHotspotPanel = new JPanel(new BorderLayout()); 
     JTextPane resultPane = new JTextPane(); 
     JPanel main = new JPanel(new GridBagLayout()); 
     JPanel header = new JPanel(new BorderLayout()); 

     header.setBackground(Color.WHITE); 
     frame.setLayout(new BorderLayout()); 
     frame.setMinimumSize(new Dimension(875, 600)); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

     Dimension dim = Toolkit.getDefaultToolkit().getScreenSize(); 
     frame.setLocation(dim.width/2-frame.getSize().width/2, dim.height/2-frame.getSize().height/2); 
     resultPane.setOpaque(false); 
     resultPane.setEditable(false); 
     GridBagConstraints c = new GridBagConstraints(); 
     DocumentFilter filter = new UppercaseDocumentFilter(); 
     JTextField geneField = new JTextField(10); 
     ((AbstractDocument) geneField.getDocument()).setDocumentFilter(filter); 
     geneField.setMinimumSize(geneField.getPreferredSize()); 
     JTextField proEffField = new JTextField(10); 
     proEffField.setMinimumSize(proEffField.getPreferredSize()); 
     String[] mutTypes = { "missense", "nonsense", "frameshift", "nonframeshift"}; 
     JComboBox<String> mutTypeComboBox = new JComboBox<String>(mutTypes); 
     JButton saveResultsButton = new JButton("Save to TSV"); 
     JPanel glass = (JPanel) frame.getGlassPane(); 
     JButton clearButton = new JButton("Clear"); 
     JButton cosmicButton = new JButton("To COSMIC"); 
     JButton dataButton = new JButton("Show Data"); 
     dataButton.setEnabled(false); 
     JButton goButton = new JButton("GO"); 

     c.weightx = 1.0;c.gridx = 0;c.gridy = 0;c.anchor = GridBagConstraints.EAST;c.ipadx=5;c.ipady=5; 
     main.add(new JLabel("Gene: "), c); 
     c.gridx = 1;c.gridy = 0;c.anchor = GridBagConstraints.WEST; 
     main.add(geneField, c); 
     c.gridx = 0;c.gridy = 1;c.anchor = GridBagConstraints.EAST; 
     main.add(new JLabel("Protein Effect: "), c); 
     c.gridx = 1;c.gridy = 1;c.anchor = GridBagConstraints.WEST; 
     main.add(proEffField, c); 
     c.gridx =0;c.gridy = 2;c.anchor = GridBagConstraints.EAST; 
     main.add(new JLabel("Mutation Type: "), c); 
     c.gridx =1;c.gridy = 2;c.anchor = GridBagConstraints.WEST; 
     main.add(mutTypeComboBox, c); 
     c.gridx =0;c.gridy = 3;c.anchor = GridBagConstraints.WEST; 
     main.add(saveResultsButton, c); 
     c.gridx = 0;c.gridy = 3;c.anchor = GridBagConstraints.EAST; 
     main.add(goButton, c); 
     c.gridx = 1;c.gridy = 3;c.anchor = GridBagConstraints.WEST; 
     main.add(clearButton,c); 
     c.gridx = 0;c.gridy = 3;c.anchor = GridBagConstraints.CENTER; 
     main.add(dataButton,c); 
     c.gridx = 1;c.gridy = 3;c.anchor = GridBagConstraints.EAST; 
     main.add(cosmicButton,c); 
     c.gridx = 0; c.gridy =4;c.gridwidth =1; c.weightx = 1.0;c.weighty = 1.0; c.fill = GridBagConstraints.BOTH; 
     JScrollPane scrollPane = new JScrollPane(resultPane); 
     main.add(scrollPane, c); 
     c.gridx = 1; c.gridy =4;c.gridwidth = 1; c.weightx = 1.0;c.weighty = 1.0; c.fill = GridBagConstraints.BOTH; 

     hotspotPanel.add(subHotspotPanel, "SUBPANEL"); 
     hotspotPanel.add(indelHotspotPanel, "INDELPANEL"); 
     hotspotPanel.add(new JPanel(), "BLANK"); 
     main.add(hotspotPanel, c); 
     frame.add(header, BorderLayout.NORTH); 
     frame.add(main, BorderLayout.CENTER); 

     frame.pack(); 
     frame.setVisible(true); 
    } 

}

このexampleを使用して、それがChartPanelがCardLayoutで正常に動作することは明らかです。以下の例では、の初期サイズを設定するために、hereと表示されているようにgetPreferredSize()を上書きしています。各カードでGridLayoutを使用すると、囲み枠のサイズが変更されたときにグラフがパネルに表示されます。
