本文整理了Java中org.openide.nodes.Node.getPreferredAction()方法的一些代码示例，展示了Node.getPreferredAction()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Node.getPreferredAction()方法的具体详情如下：
包路径：org.openide.nodes.Node
类名称：Node
方法名：getPreferredAction

Node.getPreferredAction介绍

[英]Gets the preferred action for this node. This action can but need not to be one from the action array returned from #getActions(boolean). In case it is, the popup menu created from those actions is encouraged to highlight the preferred action. Override in subclasses accordingly.
[中]获取此节点的首选操作。此操作可以但不必是#getActions（布尔值）返回的操作数组中的操作。在这种情况下，鼓励从这些操作创建的弹出菜单突出显示首选操作。相应地在子类中重写。
