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 I hava 3 tabs in a TabPane that each one has a text area with different texts and different length. I want to autosize text area according to it's length in each tab. I don't understand what should I do ? using scene builder ? css ?javaFX methods ? Thank's in Advance ... 回答1: I think you are asking that the text areas grow or shrink according to the text that is displayed in them?

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

问题 Just wondering how to insert an image into cells of a TableView in JavaFX. I have read other peoples solutions on this site but struggle a tad understanding them as I think their set up is a bit different to mine. Pretty much I am making a game library, and in the tableview I want an icon of the game. The data is being read from a .dat file (in which this case a String of the icon's URL), and all the strings in the rows work. The column is made @FXML private TableColumn<Game, Image> iconCol;

问题 The Translate Transition does not output. It uses a method in the main class. I believe it is not working because it is used as an object. There has to be a different code to implement. It uses a method in a main and then puts it into a tester. However, I do not know how to use it because it uses a constructor/object as well. Then, the object turns and changes into a node which I changed it. I do not know how the Translate Transition method is attached to the object and displays it into the

问题 can someone please tell me the simplest way to achieve the layout in the image below in Java? The JFXPanel should take all the screen space except for the button that should remain of the same size when the window is resized. More generally, is there any LayoutManager in Java that lets me stack components one over the other in a simple way? Everything I've tried makes the button way too large. Maybe the JFXPanel messes with the sizing, I don't know. Thank you, this is driving me mad. 回答1: Use
