java内容不局限于JPanel

2 周，3 日 Questions & Answers 101

我在JavaFX项目的锚定窗格中有一个JPanel。我遇到的问题是，面板中加载的内容并不局限于面板，一旦文本到达面板边缘，就会将其切掉，而不是移动到下一行

不过，如果我在Jframe中测试面板，这是可以的

锚面板是使用Scene Builder for JavaFX创建并放置在用户界面中的。下面是我制作各种字体大小的标签（这是为了创建一个单词云）并将它们放在一个JPanel中，然后返回这个面板的代码

public JPanel nnsePairWordCloud() throws SQLException, InstantiationException, IllegalAccessException {
Database databaseConnection = new Database();
databaseConnection.getConnection();
ResultSet nnsePairs = databaseConnection.getNNSEPairInfoFromDatabase();
ResultSet nnseScores = databaseConnection.getNNSESimilarityResultsFromDatabase();

//adding words from the database to the array that will make up the word cloud
while(nnsePairs.next()) {
    String wordPair = nnsePairs.getString(1);
    WORDS.add(wordPair);
}

//adding each pairs weighting from the database - this will determine the size of the word
while(nnseScores.next()) {
    Double wordResult = nnseScores.getDouble(1);
    WEIGHTINGS.add(wordResult);
}
System.out.println("cloud data got");

  JPanel panel = new JPanel();
    panel.setSize(380, 275);
    Cloud cloud = new Cloud();
   // cloud.setMinWeight(-1);
    //cloud.setMaxWeight(1);
    cloud.setMaxTagsToDisplay(300);
    //Random random = new Random();
    for (int i =0; i<WORDS.size(); i++) {
            cloud.addTag(new Tag(WORDS.get(i), WEIGHTINGS.get(i)));
    }
    for (Tag tag : cloud.tags()) {
        final JLabel label = new JLabel(tag.getName());
        label.setOpaque(false);
        label.setFont(label.getFont().deriveFont((float) tag.getWeight() * 10));
        panel.add(label);
    }
    //frame.add(panel);
    //frame.setSize(800, 600);
    //frame.setVisible(true);
    return panel;

}

下面是返回并设置面板的代码——首先创建SwingNode，然后加载内容。我必须这样做，这样才能在JavaFXUI中加载内容

final SwingNode nodeForWordCloud = new SwingNode();
    createAndSetSwingContentForWordCloud(nodeForWordCloud);
    wordCloudBox.getChildren().add(nodeForWordCloud);

 private void createAndSetSwingContentForWordCloud(final SwingNode swingNode) {
         SwingUtilities.invokeLater(new Runnable() {
             @Override
             public void run() {
                 try {
                     swingNode.setContent(new WordCloud().initUI());
                 } catch (SQLException ex) {
                     Logger.getLogger(WordNetPairPageController.class.getName()).log(Level.SEVERE, null, ex);
                 } catch (InstantiationException ex) {
                     Logger.getLogger(WordNetPairPageController.class.getName()).log(Level.SEVERE, null, ex);
                 } catch (IllegalAccessException ex) {
                     Logger.getLogger(WordNetPairPageController.class.getName()).log(Level.SEVERE, null, ex);
                 }
             }
         });
     }
