I tested this code: private ObservableList<Data> pieChartdData = FXCollections.observableArrayList(); private PieChart chart = new PieChart(pieChartdData); public void pieChart(List<FSPartitions> obj) { for (FSPartitions obj1 : obj) { String fsName = obj1.getFSName(); double usedSize = obj1.getUsedSize(); for (Data d : pieChartdData) { if (d.getName().equals(fsName)) { d.setPieValue(usedSize); return; } } } for (FSPartitions

问题 For some reason, JavaFX's ToolBar only proposes two options for items alignment: LEFT_TO_RIGHT and RIGHT_TO_LEFT . And funnily enough, if this is RIGHT_TO_LEFT you have to specify your items in reverse order so that they show up naturally... However I don't see any option for aligning elements in the center . How do you achieve that? Or must I use something else than a toolbar? edit: here is the current code... Unfortunately this doesn't work :( FXML: <BorderPane xmlns="http://javafx.com

UPDATE: I'm currently working on this code public class

问题 I have a problem with Context menu. Following this topic I found that there is a limitation when I try to load Context menu insight JavaFX Task.
