将ChartPanel添加到CardLayout [英] Adding ChartPanel to CardLayout
本文介绍了将ChartPanel添加到CardLayout的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个非常基本的GUI，用 GridBagLayout 组织。最复杂的部分是West用ScrollPane填充的底部，右边是一个带有 CardLayout 的面板，它有多个ChartPanel，所以我可以在几张图之间切换。
当我启动程序时出现问题。
在我向任何方向调整框架大小后，调整大小的问题就消失了。我已确认图表面板是问题，因为没有将其添加到 CardLayout 面板修复它。我创建了一个空白 ChartPanel 并在稍后采取一些操作后填充它但这就是我所做的：
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）;
}
}

I have a pretty basic GUI organized with a GridBagLayout. The most complex portion is the bottom where West is populated with ScrollPane and the right is a panel with a CardLayout that has multiple ChartPanels so I can switch between a few graphs.
My issue comes when I start the program.
The resizing issue goes away after I resize the frame in any direction. I have confirmed the chartpanel is the issue because not adding this to the CardLayout panel fixes it. I create a blank ChartPanel and populate it later after some action is taken but this is what I've done:
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);
}

解决方案
Using this example, it's clear that a ChartPanel works correctly in a CardLayout. The example below overrides getPreferredSize(), as shown here, to establish an initial size for the ChartPanel. The use of GridLayout on each card allows the chart to fill the panel as the enclosing frame is resized.
