问题 I'm trying to do something pretty simple. I want to place an icon in a column for a particular row in a table. If it's a folder, display a folder icon. If it's a file, display a file icon.

问题 I can listen for scroll events: tableView.addEventFilter(javafx.scene.input.ScrollEvent.SCROLL, new EventHandler<javafx.scene.input.ScrollEvent>() { @Override public void handle(final javafx.scene.input.ScrollEvent scrollEvent) { System.out.println("Scrolled."); } }); But How can I be notified if the bottom/ top of the table is reached? 回答1: A simple way of doing this is to retrieve the ScrollBar using a lookup : ScrollBar tvScrollBar = (ScrollBar) tableView.lookup(".scroll-bar:vertical");
