java - JXTreeTable 可编辑示例？

Question

可编辑的 JxTreeTable 是否有任何工作示例。我确实尝试了一些方法。但没有运气......只有第一列是可编辑的。

如何使所有列都可编辑？

对不起各位，

这是我的源代码:

    BorderHighlighter border = new BorderHighlighter(new ColumnHighlightPredicate(1, 2), BorderFactory.createEmptyBorder(0, 6, 0, 6), false, false);
    addHighlighter(border);

}class RandomTextTreeTableModel extends DefaultTreeTableModel {

DefaultMutableTreeTableNode Root = null;

RandomTextTreeTableModel(int i) {
    Root = new DefaultMutableTreeTableNode();
    this.setRoot(Root);
    for (int x = 0; x < 5; x++) {
        DefaultMutableTreeTableNode node = new DefaultMutableTreeTableNode("HI");
        Root.add(node);
        for (int j = 0; j < i; j++) {
            node.add(new DefaultMutableTreeTableNode(j));
        }
    }
}

@Override
public String getColumnName(int column){
    return "dsdsddds";
}

@Override
public int getColumnCount() {
    return 2;
}


@Override
public Object getValueAt(Object arg0, int arg1) {
    if (arg1 == 1) {
        return new String("hi " + arg0.toString());
    }
    return arg0;
}
}

谢谢....我想编辑所有栏目。但是此代码仅适用于第一列。

这是一个简单的例子，简单的步骤

• 实现自定义可编辑的 TreeTableNode，扩展 AbstractMutableTreeTableNode
• 在 DefaultTreeTableModel 中使用它
• 用模型实例化一个 JXTreeTable

在代码中:

/**
 * A custom node implementation.
 */
public static class ArrayNode extends AbstractMutableTreeTableNode {

    public ArrayNode(Object[] data) {
        super(data);
    }

    @Override
    public Object getValueAt(int column) {
        return getUserObject()[column];
    }

    @Override
    public void setValueAt(Object aValue, int column) {
        getUserObject()[column] = aValue;
    }

    @Override
    public int getColumnCount() {
        return 2;
    }

    @Override
    public Object[] getUserObject() {
        return (Object[]) super.getUserObject();
    }

    @Override
    public boolean isEditable(int column) {
        return true;
    }

}

// usage
ArrayNode root = new ArrayNode(new Object[] {"root", ""});
for (int i = 0; i < 5; i++) {
    root.add(new ArrayNode(new Object[]{"child", "" + i}));
}
JXTreeTable table = new JXTreeTable(new DefaultTreeTableModel(root));
