JTree问题，当我修改JTree节点上的字符串时，当修改后的长度比原来的长，就会在节点上显示...我该怎么样才能显示完整？

Question

研究下javax.swing.tree.TreeCellEditor

Answer 1

public Component getTreeCellRendererComponent(JTree tree,
                                              Object value,
                                              boolean selected,
                                              boolean expanded,
                                              boolean leaf,
                                              int row,
                                              boolean hasFocus)
这个方法很有用。
