Only when they differ. An example: I have a ListView<Element> binded with an ObservableList<Element> containing some "elements". I can add more elements in

问题 I'm new to Java FX and am creating an application for fun. I'm trying to add a TitledPane dynamically and am getting Null Pointer Exceptions when attempting to lookup the title of the TitledPane about 70% of the time. I tried to create a simple demo of my issue, but was unable to reproduce the issue outside of my application, but I could solve my issue.

问题 I would like to make the 'folder' nodes in my JavaFX TreeView expandable and collapsible but not selectable . I found this discussion and looked into EventFilter , but there does not appear to be any EventType that corresponds with TreeView selection changes.

So, am I stuck allowing the selection events to trigger my listener and then sort through the trash there? 回答1: It's a bit hacky, but I ended up doing it
