Question

我一直在寻找一种使用复选框开发JTree的方法，然后我找到了这个答案：https://stackoverflow.com/a/21851201/5988526 它以某种方式有用，对我来说很好用，它会生成默认数据（颜色，食物等），但是当我尝试输入数据时，节点仅显示前2个字母，例如，节点文本为“ Cimetiere”，并且仅显示“ Ci ..”

package View;
import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTree;
import javax.swing.SwingConstants;
import javax.swing.tree.DefaultMutableTreeNode;
import javax.swing.tree.DefaultTreeModel;
import javax.swing.tree.TreePath;

public class TransfertUI extends JFrame{

    JPanel panel = new JPanel();
    private JLabel lTitre = new JLabel("Opération de ransfert");
    JPanel pSouth = new JPanel(new FlowLayout());
    private JLabel label = new JLabel(">>", SwingConstants.CENTER);
    private JButton bValider = new JButton("Valider");
    private JButton bAnuuler = new JButton("Anuuler");

    public TransfertUI() {
        JCheckBoxTree tree1 = new JCheckBoxTree();
        JCheckBoxTree tree2 = new JCheckBoxTree();


        DefaultMutableTreeNode cimetiere=new DefaultMutableTreeNode("Cimetiere");  
        DefaultMutableTreeNode carre1=new DefaultMutableTreeNode("carré 1 ");  
        DefaultMutableTreeNode carre2=new DefaultMutableTreeNode("carré 2");  
        cimetiere.add(carre1);  
        cimetiere.add(carre2);  
        DefaultMutableTreeNode t1=new DefaultMutableTreeNode("tombe 1");  
        DefaultMutableTreeNode t2=new DefaultMutableTreeNode("tombe 2");  
        DefaultMutableTreeNode d1=new DefaultMutableTreeNode("defunt 1");  
        DefaultMutableTreeNode d2=new DefaultMutableTreeNode("defunt 2");  
        carre1.add(t1); carre1.add(t2); t1.add(d1); t2.add(d2);  



        DefaultTreeModel model = new DefaultTreeModel(cimetiere); 
        tree1.setModel(model);
       // tree2.setModel(model);

        JScrollPane scrollPane1 = new JScrollPane(tree1);
        JScrollPane scrollPane2 = new JScrollPane(tree2);





        panel.setLayout(new GridLayout(1,3));
        panel.add(scrollPane1);
        panel.add(label);
        panel.add(scrollPane2);

        this.setLayout(new BorderLayout());

        pSouth.add(bValider);
        pSouth.add(bAnuuler);
        this.add(pSouth,BorderLayout.SOUTH);
        this.add(lTitre,BorderLayout.NORTH);


        this.add(panel,BorderLayout.CENTER);
        this.setSize(650, 400);
        this.setDefaultCloseOperation(EXIT_ON_CLOSE);
        this.setVisible(true);
        this.setTitle("Opération de transfert - Finalys");
    }


    public static void main(String[] args) {
       new TransfertUI();
    }


}

在这里您可以看到结果。对于默认数据，它显示的很好，当我输入数据时，它出错了
