存储状态/jtree的扩展节点以恢复状态 [英] store state/expanded nodes of a jtree for restoring state

问题描述

我正在使用JTree.

I am working with JTree.

我想知道什么是最好的方法，即知道在JTree中扩展哪些节点以保存其状态(即保存所有扩展路径).这样，如果我调用model.reload()，Jtree不会保持折叠状态，但是我将能够将其原始状态恢复给用户，即所有展开的节点都将被展开.

I would like to know what is best the way to know which nodes are expanded in a JTree so as to save its state (i.e. save all expanded paths). So that if I call model.reload() the Jtree would not stay collapsed, but I will be able to restore its original state to the user, i.e., all expanded nodes will be expanded.
