將ChartPanel添加到CardLayout中

Question

我有一個非常基本的GUI，組織了一個GridBagLayout。最複雜的部分是West用ScrollPane填充的底部，右邊是帶有CardLayout的面板，該面板有多個ChartPanel，因此我可以在幾張圖之間切換。

當我啓動程序時出現了我的問題。

的大小調整問題消失後，我調整在任何方向的框架。我已經確認該chartpanel是問題，因爲沒有將此添加到CardLayout面板修復它。我創建一個空白ChartPanel後來填充它採取一些行動後，但是這是我做了什麼：

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); 
    } 

}

使用該example，很明顯，一個ChartPanel工作正常在CardLayout。下面的示例覆蓋getPreferredSize()，如圖所示here，以建立ChartPanel的初始大小。在每個卡上使用GridLayout允許圖表在封閉框架調整大小時填充面板。
