设置JavaFX TreeView线条样式 [英] Setting JavaFX TreeView Line Style

问题描述

在Java Swing中，有JTree.linestyle属性，该属性启用/禁用将树中的父节点连接到其子节点的线. JavaFX 2中有类似的东西吗?在我查看过的JavaFX的所有TreeView示例中，我都没有看到.我也没有看到要设置的CSS属性.

In Java Swing, there is JTree.linestyle property that enables/disables lines connecting the parent nodes in a tree to their children. Is there something similar in JavaFX 2? In all of the TreeView examples I've looked at for JavaFX, I haven't seen this. I also didn't see a CSS property to set.

推荐答案

JavaFX 2.2没有开箱即用的设置. 可以在 JavaFX问题跟踪器中提出功能请求.

JavaFX 2.2 does not have such a setting out of the box. A feature request could be filed in the JavaFX issue tracker.

通过创建自定义的TreeCell和TreeItem节点，然后在这些节点上设置

You may be able to achieve the line connection effect by creating custom TreeCell and TreeItem nodes and, on those, setting the treeCell.disclosureNodeProperty and the TreeItem graphicProperty as appropriate based upon the various settable event handlers for the TreeItem.
